Do you need a crush washer for the fill plug, drain plug, or both? I'm not 100% certain, I'd have to check when I get home, but I thought the diff drain plug washer was the same as the engine oil. Can anyone verify?

 

My recommendation: If you find yourself at a Honda dealer that does not stock the correct filters, washers and fluids for routine maintenance for a S2000, leave immediately! This is nonsense, so what other short cuts are they taking during the service?

 

Umm, I think one of the Trans washers is the same as the oil. The diff bolts are bigger if I remember correctly.

 

Diff washer p/n: 90402-PCZ-003 and 90401-PCZ-003
They were about $0.50 each at the dealer.

 

When I got my car, I had the parts dept at the dealer order 10 of each for the trans and diff, got them a week later, and never had to worry about washers since. That was the cheapest option then, and I'd imagine its the same now.

 

I only use my dealer for parts, I do all service myself.

And yeah, I only need the washers for the diff, which at least one (the drain bolt) is a different size than the transmission/oil bolts. Quite frankly, given that Honda doesn't make an OEM diff fluid, I don't know how the Honda dealer does diff fluid changes anyways.

I'll just order a couple extra parts from HandA to make the shipping cost more reasonable; I'll stock up on some stuff, and I was thinking of buying this to keep in the car anyways.

 

Yeah, I actually ordered a few of each when I was at the dealer a few weeks ago, but they never called me.


Actually...just called them. They got them in. Nice of them to call

 

The "HELP!" section of autozone usually has a pack of different size crush washers.
