Question about 1996 Ford Escort 4 Door
I have a 2001 VW Jetta VR6, I have had the water pump & thermostat replaced, radiator, block and heater core flushed and I am still getting the humming noise and over heating. Only happens when sitting in traffic. I turn the heater on full blast to try to cool down the engine. The fans have been checked and are working fine. Mechanic can't seem to figure out the problem and I can't afford to keep paying him for maybe's. Once I start moving, it cools down, but starts to heat up again when I am sitting. My commute is a little over an hour, this happens about 40 minutes into my commute, but only when I am sitting in traffic, never when I am cruising along. Any ideas?
You might want to check the tention on the belt that drives the water pump, also give the pully for the water pump a good shake to see if the bearings are starting to go, the impeller blade may not be able to keep up at idle RPM

The humming is the noise the coolant makes when the car overheats and forces open the relief valve in the radiator cap and flows through the small hose to the recovery bottle., it you had all this work this done only 2 things can cause the issue, one is a problem with the cooling fan, the other is a blown head gasket, which I suspect is the problem, before you flushed the system was the coolant rusted?
