DIY : Honda Civic/Integra 92-00 Condenser Fan Motor Carbon Brushes Replacement

Posted in My Automotive Life | No Comments »

This is could be another good preventive maintenance that we overlooked, after your car run over 150 000km, the condenser fan is very important part for the heat exchange system to help the condenser dissipation heat efficiently from hot compressed gasses supplied by the compressor, if it failed, it may cause idle problem when you turn on the air conditioning system.

First thing is to remove the fan by remove the bolt that hold the fan (blue circle).

Unplug the fan motor socket and remove the few relay (for the space) and remove the bottom right bolt…

and the bottom left side.

I also remove the exhaust manifold heat shield for the space…

and the radiator fan too! (this is a good change to replace radiator fan motor carbon brushes). By removing 4 bolts that attached the fan to the radiator.

To remove the motor from the casing and the fan blade is a piece of cake.

Here we go.

Remove the 3 locking tabs by using chisel or flat screwdriver (not proper, but it’s work!) with hammer.

Cleaning time!

The carbon brushes seem at the dead end. Unfortunately, I did not found the perfect shape for the replacement, so, I modified from the alternator carbon brushes using file (I mean…a tools file) and small grits sand paper.

Need a patient booster…

Cut the middle of the old carbon brushes wire, and cut the new one exactly same length with the old one, soldering together, put back everything, fortunately, there is spring holder pin (red circle), important : Don’t forget to release it back after you Insert the rotor.

Polishing the commutator using small grits sand paper.

Check for the worn bearing, replace if need, mine like the new one!

Reinstall everthing, important : don’t forget to stake back the motor casing locking tab using chisel or other method, I believe it will go for another 150 000km and save your precious money from buying the new motor.

DIY : 92-95 Honda Civic Nippondenso Alternator Whining & Carbon Brush & Bearing Replacement

Posted in My Automotive Life | 6 Comments »

When I turn on all heavy load, I mean amp load (air-conditioner, headlights (HI), fog lights, audio system, etc.) the alternator will start make whining noise like my blander machine. Inspection & suspecting;

1. I measure the battery voltage (engine at the normal operating temperature), seem normal, between 13.9 – 15.1 Voltage, depend on the load as long as it doesn’t exceed and below the range (to improve fuel economy, the alternator control system within the PGM-FI ECU changes the voltage generated at the alternator in accordance with the driving conditions). That mean my battery is under charge and voltage regulator is functioning.

2. I didn’t suspect the bearing, worn bearing will whining all the time.

3. Check the belt condition and belt deflection (5-7mm), seem OK.

4. Luckily, I have the spare alternator, take from the car graveyard, make the replacement, no more whining anymore! So, that’s mean, my alternator almost at the dead end, the whining come from electrical noise, the replacement is essential.

This is the step for alternator replacement, disconnect the cable from the battery negative (-) terminal and disconnect the alternator connector from the alternator. Remove the terminal nut and the white wire from the B terminal.

Also, don’t forget to dis-clip the white cable that attach to the alternator body.

Alternative – Make more work space by dis-clip the wire connectors. You will see clearly the adjusting nut.

Remove the adjusting nut and then remove adjusting bolt.

Jack stand the car, remove the left tire and under the alternator, there is alternator through bolt, remove it.

Loosen the belt by moving the alternator and then, remove it. Then carefully take out the alternator.

If you just want to make the new alternator replacement, just install everything back in the reverse order of removal, make sure everything in their place, and make the belting adjustment by adjusting the alternator adjusting bolt. But in my case, I need to refreshing my used alternator by cleaning, replace the bearing and the carbon brush.

At the alternator end cover, remove everything in the blue circle (This is how I use to short my text)

And again. Then remove the voltage regulator, diode and brush holder.


Inspect the slip rings, not in the bad condition…

Remove the pulley locknut (it is easy if you have an impact wrench/gun) and remove the pulley.

Loosen the rear housing (I used flat screw driver) from drive end housing.

Knock a little bit to loosen the housing.

Tap down the rotor shaft at the solid surface to split the housing, be careful, not too much. I don’t know what to call this method, but it’s work!

Remove the rotor by using the bearing puller.

Polishing the slip rings using small grits sand paper.

Check the continuity between the slip rings and no continuity between slip rings and the rotor or rotor shaft.

New set of carbon brush, make by TRIS Inc. , carbon brushes specialist company from Japan.

The old one still could be use, as long as you could see the company logo , but it is a good practice to replace alternator carbon brush that run over than 200 000 km.

Alternator brushes length : Standard : 10.5mm, service limit : 5.5mm.

Soldering set.


Alternator brushes length : Standard : 10.5mm


Remove the bearing retainer.

This is how I remove the front bearing, using suitable socket, and hammer it out.

Comparison with the old and the new bearing (KOYO 437 vs NSK 817-101DG8B).

The better procedure to install the bearing is using the press machine.

Install back the bearing retainer.

Comparison with the old and the new bearing (NSK 399 vs NSK 6202DW).

Use the same method from the previous one to remove the old bearing, be careful with the spacer ring.

In my case I am using 27 deep length socket size.

The better procedure to install the bearing is using the press machine.

Insert back the rotor into the big and small bearing housing using hand force.

Using back 27 deep length socket size to cover the slip rings.

Hammer down the rotor shaft until the two halves close together and tighten the four nuts to fasten the casing together.

Install everything back in the reverse order of removal, make sure everything in their place, easy right?

DIY : Honda Civic/Integra Distributor Oil Seal and O-Ring Replacement

Posted in My Automotive Life | 4 Comments »

I think, I frequently write about leaking oil, yeah, this is another story…

Once upon a time, the old O-Ring become very old until he didn’t care about what goes around anymore…

DISCLAIMER: I can not say this is the best or safest way to do. I am not
responsible for any thing you damage, or what ever harm you cause to
yourself or others. This is how I did it and it worked for me.

Some oily below the distributor? Sometime, this old O-Ring playing tricks on you, until you thought, your head is leaking! (I mean, your engine head). There will be oil around the corner, where the block mate with the head, this is good replacement after you replacing the camshaft plug and VTEC solenoid gasket.

This procedure is specifically for Honda Tec distributor, other brand may have same or different procedure. So, the first step is to remove the 2-P connector from the distributor.

I didn’t remove the spark plug cables for easy installation. Remove three distributor cap bolts.

Marking the related position between distributor and cylinder head, to make sure the ignition timing didn’t out of spec during installation.

Then, remove the distributor mounting bolts, then remove the distributor from the cylinder head. As you could see the picture below, where is the leaking point and O-Ring that responsible for this problem location (external leak). If you just want to change this O-Ring only, ignore the entire procedure below, just make sure everything is clean and install the new O-Ring.

The consequence.

To prevent 180° out of time when install back the distributor end, mark the center shaft and distributor end. Note : The lugs on the end of the distributor and its mating grooves in the camshaft are both offset to eliminate the possibility of installing the distributor 180° out of time.

Turn circlip remove point to the pin hole, flat screw driver is good enough to remove this circlip.

Turn the distributor ignition rotor until you see the screw that hold the rotor, remove the ignition rotor and leak cover.

Remove three screws (cream color circle) that hold the ignition control module (ICM), TDC/CKP/CYP sensors and two screws (black color circle) that hold the ignition coil.

Remove the wires grommet.

Optional : Remove the two last TDC/CKP/CYP sensors for more work space. TheTDC/CKP/CYP sensors have a small bump on the bottom that fits into corresponding holes in the distributor case so that the sensors will only fit in one place and can’t be adjusted.

My oil seal seem ok, there’s no major leak, but, it’s a good practice to change it since it run over 100k.

This is what the entire system look like.

Pull out the oil seal using the flat screw driver, it should be easy.

Cleaning time! I clean using silicone spray. Before:


There are 2 type OEM Honda distributor O-Ring common type. The dealer tell me that OEM Honda distributor O-Ring make from viton material, that why the price is high that normal rubber type (about 4 times!).


Install the new oil seal, make sure the seal seat properly, I using 14mm socket to slowly push it down.

Install back all together reverse of removal, install the new O-Ring, and don’t forget the marking points that I mentioned before or your engine won’t start.

Install the distributor on the cylinder head,  don’t forget the ignition timing marking point! That all, wait for the next chapter of the leaking oil story (I hope not!).

How to Repair Snap/broken Bolt/Stud Using Hand Tapping

Posted in Others | 2 Comments »

This is nightmare for some people, including me, do you recognize this special stud? The 10mm bolt/stud is easily over-torque.

DISCLAIMER: I can not say this is the best or safest way to do. I am not
responsible for any thing you damage, or what ever harm you cause to
yourself or others. This is how I did it and it worked for me.

Grinding the surface.

For 10mm bolt, using the M6x1.0 (M6 mean the major (nominal) diameter of the thread and 1.0 is the pitch of the thread) tap and 5mm (the major (nominal) diameter of the thread – is the pitch of the thread = 5). From left, drill, taper tap, plug tap and bottom tap.

You also need the tap wrench. There are two main types of tap wrenches: double-end adjustable wrenches and T-handle wrenches. Double-end adjustable wrenches, also known as bar wrenches, have one threaded handle which is attached to one of the clamps. The clamp is opened to insert the tool and then tightened down against the tool to secure it. This type of tap wrench is used with larger taps and where there is room for a larger wrench, because a T-handle is more compact.

Before drilling, punch the stud center to keeps the drill bit from wandering around when you start drilling.

Make sure the hole is 90° and deep enough.

Tips before and during tapping :

1. Make sure the cutting teeth is always stand straight 90° around (left, right, front, back).

2. Use lubricant, example : Tapping fluid, WD-40, engine or machine oil or even your blood (just kidding) to reduce friction binding and aid in chip removal.

3. Take the time, taps are brittle (make from HSS – High Speed Steel) go slow, or you will need another tool, broken tap removal!

4. After 1 – 3 thread(s) (you will feel a little bit tight), move the tap counterclockwise and anticlockwise to remove the chips of loose material.

5. Be patient.

For starting, use the tapper tap, make several threads (usually the first 3-5 threads), then use the plug tap for further threads, and bottom tap for finishing.


Bolt in tightly and cut the bold head.

Look like an original right?

And after several day, my friend found this at the junkyard. My super friend!

DIY : Honda Civic B-Series Engine Head/Valve Cover Gasket/Seal & Camshaft Cap/Seal/Plug Replacement

Posted in My Automotive Life | No Comments »

Leaking around the passenger side front of the engine block? Lucky, I’m not the one , probability is, come from valve cover gasket, cam cap or VTEC solenoid gasket, this is common problem for B-Series engine that just exceed 100,000kms old just like mine (me 200,000kms!)

 I just done for my VTEC solenoid gasket problem, replace the valve cover gasket, spark plug seal and VTEC solenoid gasket is just straight forward job, but to replace camshaft cap is dangerous! Especially for VTEC  B-Series engine. The risk is, you could probably to stretching and breaking the camshaft holder bolt or make your cam unbalance and breaking the camshaft itself! Wow! High risk for a  small job, I bear all this in my mind, so, I better not to do any single mistake.

DISCLAIMER: I can not say this is the best or safest way to do. I am not
responsible for any thing you damage, or what ever harm you cause to
yourself or others. This is how I did it and it worked for me.

Locate your valve cover, remove the spark plug cover.

Remove all spark plug wires (do not disconnect from the distributor cap)and the nuts circled in yellow (yellow?) follow the sequence from 1-8, and remove the other thing that attached to the valve cover (green circle). Now the valve cover is ready to come off, just wiggle it a little bit and it should pop right off.

This is the perfect time to check the timing belt condition.

Here we go! This is among the critical part, below is the loosening sequence, I recommend you to loosen the green circle bolts first. It is are good practice to put the crank at TDC, put the cams in with the key-way facing upward to prevent having the camshaft being placed at a full valve open situation causing undue tension. Wait! Before you loosen the bolts, please read the next sentences first…

The most critical part is, when you want to torque it back, I saw many people will break the bolt with their torque wrench, especially the 10mm bolt, even with 3/8″ Snap-On torque wrench which has never been out of spec and torque it properly! I think this is because they overtightened the bolt without realizing it, the torque wrench didn’t reach the target even after the specified torque because the tensile strength, come from the hardened bolt and soft aluminum thread that hold the bolt tight and the bolt itself have a high weakness point because of half thread bolt design, Specified torque : For 12mm bolt : 27 Nm (20 lb-ft) and for 10mm bolt : 9.8 Nm (7.2 lb-ft), so, that’s just a small torque, almost hand tighten,  to prevent I come out with my drilling technique, I used this method, I named it “as know as good configuration technique'” I marking every single bolt, red for bolt, blue for base (camshaft holder plate), I just stretched it a little with flat screwdriver, depend on you, as long as there are markings that permanent or temporary permanent.

Then loosen the bolt with very gently that you can, start from green circle bolts to the sequence, remember, very gently, Leave all the bolts in the holes, and take off the camshaft holder plate and MAKE SURE with all bolts stick with the the original camshaft holder holes, if not, all that you done above is useless.

Next is to remove the passenger side camshaft holder, again, gently loosen this two 10mm bolts, I think, if we frequently practice this, we will become more gentlemen I said!

Don’t pry the camshaft holder using screw driver or something to take it out! Warning, or you will regret, a light tap with a rubber mallet (don’t use a regular hammer!) or wood stick should free these up.


And this is the right time if you want to replace VTEC solenoid gasket. Clean and dry the matting surfaces.

Shopping time!

All the job above is to make sure this thing sit properly. This is metal cap wrapped with rubber. You also can use aftermarket seal make from aluminum and have a double or triple oil ring for more durability, for example from skunk2, blox, etc.

After the cleaning process, apply the liquid gasket, only the area shown below, just lightly…

Put the new cam cap. Properly install, I’m pretty sure you don’t want to repeat every step above.

But, in the end, I end up using Skunk2 Cam Seal

If you want to follow my technique, then, tighten all bolts using three step, first, finger tighten from bolt 1 to 14,

Second, tighten the bolts at the green point (invisible point, just estimated) from bolt 1 to 14,

Third, fully tighten the bolts to the blue point from bolt 1 to 14, if you want to use a torque wrench, there are also three step, for example for 10mm bolts, first : finger tighten, second : 6 Nm and lastly : 9.8 Nm. Good luck!

Install the valve cover gasket, make sure the valve cover gasket is seated securely in the corners of the recesses with no gap. Apply liquid gasket to the valve cover gasket at the eight corners of the recesses, just lightly. Actually, as long as the seal is soft we could reuse them.

Install everything back, just the opposite of removal. Make sure you tighten the valve cover bolts to about 8ft lbs, and follow the sequences, for me, hand tighten is just OK, check the engine oil, refill if needed, check that all tubes, hoses, cables and connectors are installed correctly, wait at least 30 minutes before filling the engine with oil or to turn on the engine, to make sure the liquid gasket is completely dry.

Inspect the valve cover for any oil leaks, and inspect around the cam seal as well. Clean off the area around the cam seal, and inspect later on to see if your oil leakage has stopped. Observe the camshaft cap end over the next few days of normal engine running. If there is a slight leak , you can run a bit of sealant around the end to seal it up. Otherwise do this DIY again and get it right .

Another leaking point is terminated!
