This problem appears to be solved, but I won't know for certain until we get a hot day.
I followed Pete's instructions on how to fill the cooling system. Now, on the highway, the temp stays steady around 185F. As it should.
The fan still has me confused though. When it comes on, the temperature drops very, very slowly. If I jumper the temp sensor so the fan is on all the time, the temp stays down.
So it seems to me that the fan is effective at maintaining a temperature, but not very effective at lowering the temperature. I assume that's because my rad is old.
I'm thinking about wiring up the fan so it's just on all the time. I know that's just a band aid until I eventually get a new rad. Any dire warnings against doing that?
