I replaced the the radiator cap and had the system pressure tested. Thought it was all good, but it did it again. Any ideas, or anyone with the same issue?

You can get a test kit to check for exhaust gasses in the coolant. It wasn't running hot was it when you was driving it was it? Reactions: Ghstrydr and mrjp
