Hi List,

Is there a method for testing the coolant expansion tank pressure cap?

we just drove Byron (85 GL) back up from his front hose breakdown (250
mi), and the shop that replaced the hoses filled her up with some kind
of stop leak and the cap is all gunked up.

I'm wondering if a cap failure may have contributed to the hose blow
but can't find any way to test the cap in the archives.
