I just bought a second hand 1996 Taurus GL with a 3 litre V6 Vulcan engine. The water pump innards were non existent. I had the water pump changed, but the in cabin temp gauge keeps reading between 1/4 on the gauge then up to 3/4 on the gauge and I can hear the fans kick in and the temp goes down again, but it's a constant thing. It never finds a happy median unless the car is sitting idling, then it will keep itself at halfway on the gauge.
Also, when I drive at speeds of 45-50 it seems to hold a halfway mark on the temp gauge, going up and down very little, but still does. When driving at normal highway speeds of 60-70 MPH the gauge does a seesaw, but what gets me is that the gauge will go all the way down to 1/4 again and then back up.
So my question is, WHAT THE HECK IS GOING ON? LOL. Please, I don't want to have to keep driving this car with one eye on the gauge and one on the road. Should I pull the thermostat out and run it with no thermostat for one day to see if that helps?
