My radiator cap is doomed its rubber is cracking and allows the coolant to flow into the reservoir. Car is 98 accord with 1.8 F18b engine younger brother of f22b1.

Its radiator cap was changed by previous owner and it has 0.9 bar rating on it. However when i googled i always get 1.1 bar rating caps for it.

On few forums i have heard that if you use 1.1 bar cap your system would leak as its old.

Question is what is OEM Cap Specs? and should i use it on my old system?

 

go to the dealership and save your self a headache they'll have the correct one for your specific application
