DIY : Honda Civic 1987-2000 Crack Steering Boot/Dust Seal Replacement

Posted in My Automotive Life | No Comments »

 I replace this dust seal before, using the OEM Honda, but, I think it is not durable as original, I mean the old one, this is a little ‘bit disappointed’…

Check for the leaking, if your power steering reservoir runs low, no matter how frequently you top up the fluid, you should check entire power steering system, there must be leakage somewhere. Check the steering gearbox (steering rack system), pump, reservoir, pump outlet line (high pressure), low pressure hoses and pipe. Click here if you want to rebuild the entire steering rack.

Remove the cotton pin.

I highly recommend you to using ball joint remover instead of using hammer or etc.

Marking the alignment point with the tape to make sure the wheel alignment didn’t goes so far, I also note the threads, remove the boot band and the tube clamp.

Remove the tie-rod end, it’s tough and stubborn sometime…

Remove the crack dust seal. It’s a good time to re-grease  rack end ball joint and steering rack gear, my old grease is melting, should put the high temp grease…

Insert the new dust seal, reassembly all back together using reverse step.

This is the boring maintenance that I ever do….

Car ECU Electrolytic Capacitors Leak/Burn/Dies

Posted in My Automotive Life | No Comments »

This is also a very important preventive maintenance, especially ECU (Electronic Computer Unit) over than 15 years, when the capacitor face a lifespan issue cause by temperatures and ripple currents, electrolyte leaked and will damage your beloved ECU, the most terrible disaster is, your car will stop automatically and your mood change dramatically.

I attached the bad capacitor on the Honda’s ECU that I collected from Mr. WWW, this will happen to your ECU too, it is only a matter of time, so, beware!

Scary enough? The solution is simple, replace all the electrolytic capacitor that available on your ECU board. But, make sure you buy the right and quality replacement, especially the capacitance value (µF), the voltage is not critical, as long is higher than spec, for example, if your spec is 10µF 10v, you also could use 10µF 35v or 50v, this also will give you advantage, cause usually, the higher voltage rate, the higher durability but also come with the big size dimension.

Today I will replace electrolytic capacitor on my Honda 37820-P30-901  ECU (not all P30 series Honda ECU have same capacitor number/location) , I did do original parts (Nichicon PR Series) and replacement parts comparison that I could get from Element14, I sort all the best to find the very best, this is the final list, which is stock available;

Good Capacitor Series

Listed from left to right, good to best:

  • Rubycon: YXG, YXH, ZL, ZA (disc.), ZLH, ZLG, MBZ (disc.), MCZ
  • Panasonic: FM, FK, HFQ (disc.), FC, FA
  • Nichicon: HZ, HE, HD, HV, PW, PM, PL
  • Chemicon: KY, KZE, KLH, KZG, KZH, KZJ
  • Unicon: KGM, KXM, KEM

OK, stop with the technical data, if you have skill to soldering, you will save some paper on your wallet, otherwise, you could borrow somebody skill, just  DON’T FORGET ABOUT THE POLARITY.

The targets

The parts

The tools


This is the first time I wrote other than oil leakage, current leakage also could be dangerous, didn’t see, silent, until  it appear, like a ghost! Will scare you until your wallet is leakage too…
