my rad cap seems to release pressure after stopping, causing a puddle. Its a new (to me) radiator manufactured by coolex.

Does anyone know if they take the universal size caps that come with most aftermarket rads, or are the coolex ones unique?



thanks!

It looks like the one that came with my Nissan micra rad there was a expansion tank that the water went into then it sucked the water out and back into the rad when the engine cooled
I don’t think the tops have very high pressure settings

caps fail all the time, but often just cleaning / exercising them can help. also you can turn the rubber seal over

Thanks. I'll try that.
I wasn't sure if the dimensions if the universal cap I have are slightly different to the Coolex one.
