Here's what came on our car. The radiator says "Northern" on it and looks like a 2 core. The single fan is a pusher and is around a 10" diameter. The fan turns on with the key and stays on. The water pump appears to be stock. The 454 overheats while cruising around town or if I just let it sit and idle.
The old thermostat had some seaweed looking crud in it so I replaced it. Still overheats so I'm going to try some additional air movement with a big fan to see what happens.
Any other suggestions?
