I'm in need of a little help here. I finally got my car running but now have cooling issues. I am using a 2 core alum radiator with 1" tubes. There are shrouds both in front of radiator and in back. I uses a 16' puller fan and duct air out the bottom. The front of the car is cut open so the air intake is approx 8"x24", there are also openings in the roll pan under the bumper. Hoses are routed through the firewall, under the car to the engine. I use a high volume alum waterpump. The hoses/pipes from the radiator enter the firewall just above the gas tank. On the pipe coming from the bottom of the radiator I have installed a bleeder valve as it passes through the firewall. I'm not sure I have all the air out of the system. Here is what happens... When I fire the car up in the garage it heats up to about 195 then the thermostat open and it goes back to abt 165-70. When I shut off the key at 170 the system heats up and the radiator blows fluid out the overflow. I have a 15# relief cap on the radiator. I'm not sure the front end is high enough for the bleeder to release the air. The engine is a TPI so I can't put a bleeder in the thermostat housing. A question..... Does the bleeder need to be higher than the thermostat? Any thoughts as to why radiator overheats when key is turned off at abot 170-190. Any suggestions as to how to properly bleed this thing. Any help will be greatly appreciated
Thanks, Carl
