Cool. Thanks for getting back to me. I had an extra fan from the old radiator . The old fan works. I tried the a/c test to get the fan to turn on. It took about a minute, but it did turn on, and stayed on for a short time. Weird thing now, though, but I could smell coolant and see smoke coming from the the bottom of the radiator from the bottom. There was a small puddle of water and coolant at the base of the radiator underneath the reservoir. What could that be? Hole in the radiator? I didn't see it leaking on the ground. I'll try again in the morning, but any suggestions would be cool. Thanks for getting back to me.
