blow it up and buy a new one

 

Went in to rent the pressure tester, but it's $160ish and I can't afford that right now.

 

Very sorry for the delay guys. Got the pressure tester on the way and will post results shortly.

 

The stock gauge in my 96 said mine was/is overheating. I temporarily hooked up a second gauge from a friends race car and found that it was not overheating but a bum gauge. Just a thought, Shaun

 

Pressure test went well. Held 16ish psi with no drop. Tried to test cap. As soon as it pumped past the 13psi area it would drop below 10. Should be able to hold 16. Trying a new cap today that actually holds what it should. I'll post back after I drive a bit.

 

Still overheating the same.

 

Did you bleed all the air that's in there? Is it overheating by the same amount?

 

Yes, all the air has been bled and the truck still overheats the same.

 

Make sure there is a good air path for the radiator, fins aren't folder over, no crap stuck between the condensor, and rad. You already think you have all the air out... after a nice long drive, I would check again, just for giggles. VW suggests IAT sensor... it's cheap, can't hurt..... Possible blockage IN the radiator, you may still get good flow thru it, but, there may not be enough working surface area to keep the truck cool.

 

No blockages at all. Just tried bleeding any air out and got nothing. Ran good at idle during the process but once I put a load on it (test drive) the temp shot up.
