Rad Cap is Cold?

[ssheen]

The upper rad hose is warm, however the rad cap is cold, even after driving the car for a while.

Any ideas why that would be? Just a failed cap?

you could test it by replacing it

that usually means there's no coolant in the neck of the rad. Now you gotta find out where it's going.

your probably low on coolant. I dont like crossflow radiators for this reason, once you are low on coolant you use less of your radiator.
