94 civic dx 1.5 engine. mt.

How do i know which radiator cap i need? When I talked to honda earlier this week about getting a new one, they said 2 radiator manufacturers were used for that generation civic. cap costs $21. I refuse to pay that much for a cap unless absolutely necessary.

if i go to napa how would i know which cap i would need or what is compatible with the radiator that i have? Would a generic cap work?

It doesn't matter if there's 2 manufacturerers, either one will fit. Do you mean two different types were used? In that case, check majestic honda under radiator.

under majestic with vin number typed in, it lists both Toyo and Denso radiator caps under the radiator section. I assume it wont make a difference and i have nothing stamped on my radiator that i could find to identify manufacturer.

Correct me if I'm wrong. I'm just going to get the denso and hope that it doesnt matter.

Well, I can't be certain since certain items like the A/C pump have 2 manufacturers because there are 2 different designs. (now that I think about it) Can someone confirm? What you should check up on is if your vehicle had 2 different radiators. If it didn't, then there's only one cap. Check different years for your generation vehcle and see if there's a different radiator number.

Seriously though, you can get a radiator cap anywhere. I buy oem all the time but in this case it's not worth it. Napa probably has a cap made in japan or something.
