Reply to "Overheating"

I just had the same problem, and was thinking about replacing the radiator. However, before spending the $$, you probably should verify that your problem really is the radiator.

I'd see if you can borrow one of those IR heat guns that measure temperature and see what is happening. If you see that the radiator temperature is only 120 degrees on the intake, for example, then replacing the radiator will have no effect - you have a blockage before the coolant gets there. For example, your thermostat.

In my case, I was all set to buy a new radiator when I discovered that despite an overheating engine, the radiator was sort of cool. Turns out that debris (seals, gaskets, rubber parts) had come loose and was blocking coolant flow to the radiator.

Before spending money to replace a part, I'd want to be sure that I was replacing the defective part. Put another way, addressing the cause, and not just the symptom!
