Ok. how about we try to make it heat up. disconnect the fans and blockk the air flow of the radiator with some card board and then see if it heats up, drive around the block or some thing.. keep an eye on the temp gauge..

Alright, well been a while since my last update... haven't really drove the car.

I am sure my gauge works, because last week I lost half of my coolant and the temp rose up as it would if you lose water....

Well today I purged everything again and went ahead and put some cardboard in front of the radiator (I didn't disconnect the fan because it is the mechanical fan) and I got the temp to stay steady at 185*.

forgot about this thread... and yes it has TONS more capacity, especially if its from a big block truck.

glad to see you have something figured out, but no matter how big the rad is, how can it pull heat off the engine if the thermostat is closed?
