I got a 94 EX, auto. When we got the car, the cap was bad.

I cant get ANY cap to fit. It had an OEM cap when we got it.

Do autos have different caps?

 

Is the radiator stock?

 

it looks stock. I have no reason to believe its not. The car is 100% virgin, so worst case, it might be a stock replacement

 

My radiator cap is kinda tight, but it wedges in there.

 

Get a stock oem cap, make sure you are putting it on right, if the car has an aftermarket radiator sometimes you have to wiggle it get past the ears, look closely at the radiator and the cap there are tabs on the cap that have to be inserted on the rad, then you push down and turn.

 

OEM, some aftermarket ones can make the coolant boil
