I was looking at a catalog and thought this would be pretty cool part to put on the car...$20.00

"Measure coolant temperature at the neck of your radiator—it's easy and eliminates guesswork!
Built-in calibrated gauge maximizes accuracy, simplifies measurements
Features a reclamation valve for systems with coolant overflow bottles
Lasts for years…won't rust. Please examine your existing original cap and order the valve pressure that most closely matches. "

Pretty cool. Looks a little big...but might just be the close up.

Thats how the old cars were.

I'm thinking the VII and the 1/2ton really, really, really need one, each. :cool:

I'd get one for my CobraII, but I don't think the hood would close.

haahaa, thats a big hat for a rad~cap.
