2001 Beetle GLS 2.0 Overheating- Two weeks ago the car was overheating quickly, red temperature light flashing and beeping. I changed the thermostat, flushed the radiator and filled it with new fluid. As soon as I did that, the interior heat quit working, not even warm. So I took on the task of a new water pump behind the timing belt. Sure enough the fan on the water pump was melted and mangled. Put in a new water pump, new timing belt and tensioner from napa. A week later the car was overheating again and leaking a good amount of radiator fluid from the new water pump itself. Took it off and back to Napa and put on a new one yesterday. Today, it is overheating again. What's going on?!?! I don't think there is blockage because both the inlet and outlet hoses have heat and movement. A fixya expert said to check thermo switch, I replaced it and no change. The temperature gauge is still red and beeping! Checked all fuses too. HELP PLEASE

It is possible that the pump failed because of an overheating problem. Make sure the fans run by turning on the air conditioning. They should operate as soon as it is turned on. Bad fans are a common problem. The pump should not have been leaking after replacement though. Make sure you have no leaks first and foremost. Then make sure the fans work. There is also a fan control module located in the area under the battery, but it is difficult to properly diagnose. If the fans do not turn on with the a/c, you can jump the wires at the thermo switch. One should be power, and when you jump to one wire they should go to low speed, the other high.
If you like you can ask more questions directly, I was a VW master tech from 2000 to 2008.

The fan or fans that cool the engine are not turned on until the engine coolant reaches about 225-230F, so they may not run for a long time, if it is not overheating why are you concerned.

Usually the problem with no heat and overheating is low coolant, thermostat, or a faulty water pump impeller.
The radiator may not be full of liquid coolant, or the pump may not be moving the coolant thru the block.

Temp gauge will rise quickly then instantly pin in red and oil light comes on. Continue driving, after couple of minutes it will go down. The rise quickly and do it again, sometimes causes overheat sensor...
If this truck is not overheating, then I would suspect the temperature sensor, if it is overheating then this must be repaired first. The sensor should be mounted in the intake manifold. Hope this helps, let me know
