Radiator cap leak

[joecool]

Ok....so why would the radiator neck leak after replacing the cap. With very little pressure and not even hot yet. It dribbles out under the cap. I pressure tested the radiator and it's fine and the new cap too and it's fine. Is there a special cap depth or something that I'm overlooking? Thanks

As hard as mine is to on get on I'd bet yours isn't quite on tight. It might be caught only on one side of the filler neck.

is it an aftermarket cap or a honda cap

You should feel 2 notches like on a car.
Mine is hard to get on also.
