Running Hot, Running Hot, Running Hot
As mentioned in my other posts, I recently bought a 95 RRC SWB with a blown engine. I put in a new engine supplied by Tidewater Rover.
When I got the vehicle back from my mechanic after the engine install, the weather was still cool. Once the summer warmed up, I discovered two things:
1. The AC compressor was blown and would need to be replaced.
2. Even without operating AC, the vehicle would run hot when stuck in traffic on a warm day.
I prioritized the overheating issue and had my mechanics replace the fan clutch. The difference was immediate and seemed to solve the problem entirely. I could tell the fan clutch was working better because of the distinctly louder fan sound at a cold start.
The mechanics had also planned to replace the switch for the electric fans in front of the radiator when they replaced the clutch, but the part was delayed, so we decided to forgo the switch since the clutch seemed to fix the issue well.
A few weeks later, we installed a rebuilt AC compressor. Everything was running perfectly for a while, but two weeks ago the car started running hot again when the AC was running. Since that time, it has also run hot a few times even with the AC off. After discovering this new overheating problem, I noticed that I was no longer hearing the louder fan sound from the fan clutch at cold start. I should point out that the electric fans DO kick in correctly when the AC is running.
So:
1. Could my new fan clutch have frozen up this quickly? Is there something about putting in a new AC compressor that would cause it to freeze up?
2. If it's not the fan clutch again, what else could be going on?
3. Other words of wisdom?
I very much enjoy this vehicle, but I've got to get this problem fixed!
Thanks in advance.
