Water pump is usualy good till it starts leaking out the bottom of the bearing.
A bad thermostat would cause coolant to boil within ther engine within minutes of driving , but the radiator hoses would not be hot.

Make sure the cooling system has been bled of all air and is full. Air in the system can cause overheating.Make sure the radiator cap is functioning properly. Worse case scenario is a bad headgasket.

Sounds like you had a sticking thermostat when you replaced the waterpump causing an air pocket. Replace the thermostat, and jack the front of the car so that the radiator cap is highest part of the cooling system. Then run the car and burp the air out of the coolant system.

Start up and start to overheating


Check your antifreeze level and your thermostat. Low antifreeze will cause overheating, sticky thermostat will also cause overheating.
Check your water pump. The internal pump fans may have come off

I have a 2003 Hyundai Tiburon that is overheating. How can I tell if I have a bad water pump or if it could be the thermostat. Does not appear to be a radiator leak or hose leak, but I am constantly...


If it's overheating it will lose antifreeze.I would change the thermostat first and see it it solves the overheating problem if not then worry about the water pump. Thermostats are only $7-10.

Overheating Express


is it acually getting hot or is it just the gauge on the dash saying so? a quality scan tool can show you what the coolant temp sensor is telling the pcm it may differ from the gauge.

94 cutlass supreme is overheating,all fluids are fine. I did have someone tell me i need 3 motor mounts replaced. could this be an issue of the car overheating?


Over heating can be caused by a faulty thermostat and or weak water pump and dirty radiator and old antifreeze or the radiator fan now working when at idle but should not over heat when driving. Service the cooling system if it has never been serviced before. Replace the thermostat, buy some radiator flush to clean out the radiator and heater core. Just follow the instruction and replace the antifreeze and make sure it's a 50/50 mix water/antifreeze. If you not sure how to mix it 50/50 you can buy them 50/50 premixed. Water boils at 100'C so you need antifreeze mixed with it but antifreeze does not have the same heat transfer as water so you cannot run 100% antifreeze cause it does not transfer heat fast enough and you over heat. Good luck and hope this helps. Keep me posted, Be glad to help, once you service the cooling system and your still over heating, then we look at the water pump.

Might be a weak or failing water pump... Does it leak antifreeze or do you have to add antifreeze very often? When the engine gets to operating temperature squeeze the top radiator hose and see if you can feel pressure from the water pump forcing water through it.
