I ordered new radiator hoses. I'll have time to mess with the overflow on wednesday to figure out if thats the problem or the cap is shot.

Thanks everyone for the help!

Cool.

Buy a delco cap. ACDELCO Part # RC94 {#10316828}

It sounds like this issue has been worked out, but I will toss my 2 cents in anyway....

The flat hoses are common of a defective/blocked radiator cap. So I throw in the defective cap crowd. I would change that first, and see what the change is over a couple of days. Then change the hoses as needed.

I filled up the coolant overflow and got a new radiator cap. I drove the car around for 2 days and the hoses are still collapsing after the engine cools. I guess the hoses are the problem...new hoses on the way.

10 year old hoses ftl!!!!!! let us know if it helps

Um, working on 15 years on mine... 8-)

Kirk, what kind did you get? OEM or flashy aftermarket ones?

how do you know yours are factory original?

I got gates, they are blue if thats flashy?
