The dealer says that the radiator cap is recommended to be changed every 30K.

I'm thinking about replacing all of my fluid caps with something better looking.
What to get and where to buy?

 

i would definitely get the ARC radiator cap...not sure about the oil cap, i know arc makes them too, but they don't look too good

 

I was lokoing at the Nismo caps on G35Parts. Their listed under the coupe section but I think they're the same... I just want more options.

 

that would be cool too, i think stillen has their own oil cap...ARC looks the coolest though, it changes colors when its hot

 

Ok so i feel like a noob asking this question, esp since ive been dealing with cars for awhile now. But exactly why would a dealer recommend changing the radiator cap? Whats the purpose behind that? I mean my only guess would be due to the heat..

 

Don't feel like a noob.. this is the first car I've owner with that recommendation as well.
Must be a heat thing, and the way the cap seals.

At around 60K, I lost the radiator cap in my 89 Z24. Maybe if I had replaced it every 30K, that wouldn't have happened?
Who knows

 

I think "dont qoute me here" that the heat cycling to the rubber seals on the bottom of the cap causes them to wear out

 

Wow ARC cap is 125 bucks!!

 

wow, IMO that's a bit too much for a radiator cap that you hardly are going to see...

 

Yeah, it has to be the seal thats really the only thing that can be worn out from the heat.. unless the cap itself starts to stretch and not fit as tight as it should due to heat warping it. This would explain the fact ARC has a 125 dollar cap, the seal and cap must be good material, still i wouldnt pay $125 for a cap though.

 

I found ARC caps for $40...

I'm also looking to replace the other caps... Dress up the engine bay a little.
I just don't know what to get.

 

WOw where did you find that?

 

check ebay. Just bought one for 29.99.

 

you guys either need to give the link or tell me what to search all the ARC oil caps i found the cheapest was 90 bucks.

 

Ditto, I'm ready to buy now! Where are the ARC radiator caps? I only see it for $39 free shipping at Direct Tuning.
