Engine Cooling problem
1994 Ford Taurus 6 cyl Front Wheel Drive Automatic 198757 miles
----------------------------------------------------------------
Hello,
I have a 1994 ford taurus sho. I changed the thrmostat but its still running hot.Iam running i on straight water with no coolant.I thinks Its the water pump. Can yall help me out.

I need some more to go on. does the car overheat when driving? how does the temperature guage act. Vehicles need antifreeze to help distribute the heat the engine puts out. and a mix of 50 50 is recommended most times. The most popular reasons for overheating are the thermastat, blocked lines or blocked radiator. Before putting anti freeze in back flush the system. to get out any build up and cleaning out the lines. check in front of the radiator to see if there is any build up of leaves that would cut down the air passing through the radiator to cool the engine.
