2000 Jeep Wrangler Question: overheating
Answer #1Andy Y March 12, 2009, 17:21Master
If the engine truly overheating? This might be the temperature sender failing. Here's a guide for the coolant temp sensor but I would test that with your multimeter before replacing so you don't waste any money
If the engine is truly getting hot, I would be looking at the water pump next. That's really the next in line if the new thermostat is opening normally. You're sure you've got the cooling system completely filled?
hope this helps
