I have a Nissan/Sentra 89 and is heating hot, my husband removed thermostat to keep it cool (2 years ago) is getting hot again, I guess is the water pump no working good because if i drive the needle can be in right level but if i am in a red a light the needle start going up. Is there a way to know if the water pump not working good? I don't think it is the engine. The car doesn't leak water

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd Raquel, There are a number of different reasons a car will overheat. The most common ones are worn out radiator hoses or fan belts breaking. It could also be the radiator, the thermostat, radiator cap, water pump, recovery tank, malfunction of the cooling fan or something as simple as a clamp coming loose on one of the hoses. I highly recommend that you take it to a repair shop ASAP. Tell them you only want to know what is causing the car to over heat, and to give you an estimate to fix it. Then you will decide if you want to have the work done or not. Engines hate being overheated. If you continue driving your car and it continues to overheat, you could kill then engine and then your car would be worthless. Best of Luck, Amy Mattinat

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Raquel, First I would replace the thermostat, then I would have the cooling system checked. It's possible that your overheating problem was never the thermostat and now the problem has gotten worse. You can check to make sure the coolant level is full, that the coolant that's in the vehicle is good, meaning it was changed after approx. 30,000 miles, and then you'll need to make sure that the fans are operating and there's no blockage in the system.
