So I bought a 2004 Jetta with a 2.0 automatic transmission with 23000 miles. Took it on a trip and it broken down because it was over heating. I initially replaced the ECT sensor, and it kept over heating, replacing the coolant temp switch on the radiator and thermostat didn’t change anything. I finally built the courage to replace the water pump. Come to find out the original water pumps come lo with plastic fins. They were broken in three large chunks. I put everything back together and I would let it idle and it would start to heat up after 45 minutes to an hour at idle. So I thought something was still wrong. Because the fans were not kicking on. They would only come on when I turned on the AC. So I let the car continue to heat up at idle and they kicked on at 215 degrees and quickly returned the car to operating temp of 190. Just seeing if any one can verify if the 215 degrees is the appropriate temp for the fans to kick on. They also kicked on high and not the low speed.
