You need to have a pressure check don on the radiator. this will pinpoint the leak if you dont see any leaks externally it could be a head gasket or a manifold gasket but the simplest thing to check is the thermostat. it may stuck in the close position and not letting you antifreeze circulate

I think my water pump is out. How would I know


could be the water pump but I would be looking for a larger leak, like a radiator hose, radiator tank split
most water pumps leak a slow dribble and then mostly when running
have a pressure test done on the cooling system to find the exact location of the leak

What is wrong with a saturn sl1 indicator says it is hot after running for 5 minutes


John sounds like your sensor may be bad. Next it could be your thermostat sticking use a temp gun and measure the temp of your radiator at the cap. Do not remove cap. Just take temp. If it is getting hot it should spit water out. Check to see if the electric fan is coming on the sensor to cut the fan on maybe bad or the fan. Hope this helps.

Heater blows hot air while car is moving but cold air while idling. The intake manifold was changed last spring, the thermostat has been changed 3 times and the temperature sending unit has been changed....


That sounds like the coolant level is low. If it is not the use of "stop leak" has probably caused a partial clog which restricts the flow of water unless the vehicle is turning higher RPMS. While sitting still raise the RPMS to about 2000 and see if the heater blows hot air to see if the above mentioned problems are fact.

My 2001 mazda millenia ran hot, we put water in it and it still ran hot does it sound like the thermostat?


If your car ran hot, you may need to check the radiator for a leak. You always need to add antifreeze/coolant when you add water to your car. Check you owner's manual for the type they suggest and the proper mix of water to antifreeze/coolant. I had to get a head on my motor shaved when my car ran hot and later I had to get the hoses replaced. My radiator cap died following my replacing the radiator as it was plastic and when the car overheated it damaged the cap. How long was the car running hot? You don't want to be a penny wize or a pound foolish when it comes to engine overheating problems. You can repair on the cheap now and pay a lot more in the long run. Also, in the future when your car runs hot, you can turn on the heater --yes even when it is hot outside--I recommend opening up the windows. The heater fan will help to dissipate the heat from the car engine. It does work. I hope these help. Also go to a reputable repair shop. It could be your thermostat they can have check valves which get messed up but you need to check to see if it is your radiator or if there is a leak there or in a hose.

Teperature gauge running hot and heater not working


If the car is hot and the heater blows cold air your thermostat is stuck shut or your radiator is really low on water/antifreeze check when engine is cold hasn't been ran like overnight take off the radiator cap and if it is low add so antifreeze/water if heater still blows cold air or water level is ok your thermostat is stuck shut and needs to be replaced.

2001 Ford Windstar is leaking antifreeze


Could be water pump, radiator, freeze plugs, hoses, ect. try and isolate the area by putting a piece of card board down on the ground and line up what is above it. Garages use a pressure tester on the cooling system to see where the leak is. I would guess water pump,or small bypass hose
