Question about 1997 Chevrolet Lumina

1 Answer

Engine overheating, no heat to interior.

Replaced Water Pump and Thermostat, seemed okay for about 50km. After 7 hours standing, Engine stayed overheated. and no heat to the interior. No water in oil, on the dipstick there are no milky signs. Could that be just an air lock or possible head gasket leak. Would a Coolant flush resolve the problem?

First off you have no heat most likely because you have no water. Did you bleed all air out of the line once you refilled it. the 3.1 has a bleeder screw to allow all air out. If that was not done you will be driving down the road and you will hit a air bubble that will cause your car to overheat!

What could cause my car to over heat when I replaced my water pump and thermostat

Hello Martin, I have seen someone install a thermostat upside down . This causes the thermostat to not open . Was the engine overheating before you replaced the water pump and thermostat ? If the engine has been excessively overheated, this could cause a blown head gasket .

Sounds like you have air in the coolant system.. did you bleed the system after you replaced all this?.. did you replace the thermostat? You might add a comment about why you replaced these things .. and how you know they were failing>

1996 nissan altima no cabin heat, new radiator, flushed and filled, top hose hot, lower hose cold, newer thermostat checked good

HI Anon.
Remove your radiator cap (WHEN ENGINE IS COLD), run the motor and let it warm up a minute or two, have someone rev the engine a little while looking into the radiator. If the water goes down and/or you see the water moving, your water pump is good. If not this means that your water pump is bad and is not moving enough water through the system. Try Removing your thermostat and run the engine without it. Keep checking the radiator hoses to see if they are the same temperature. If they are not the same temperature the water pump is bad. If they are the same temperature your thermostat is more than likely the culprit. Hope this helps.

I am not aying that this is what I think it is but I found this on your year BMW

Some BMW, Volkswagen and Audi cars have a common problem that the water pump impeller becomes dislodged from the input shaft of the water pump leaving the water pump looking ok from the outside, but failed on the inside. If your car experiences this problem it will over heat rapidly much like a thermostat failure. For exact specific repair procedures for this repair visit our online repair manual page.

Failed BMW, VW, Audi Water Pump Troubleshooting Procedure
  • Check Water Pump Operation - To troubleshoot this problem first drain about a half a gallon out of the cooling system, next remove the thermostat from the engine. With the thermostat out start the engine (stand back) coolant should be forced out of the thermostat port, if not the impeller has dislodged itself from the water pump input shaft and needs to be replaced. To replace the water pump finish draining the remainder of engine coolant, remove the serpentine belt and coolant hoses. Next remove the water pump mounting bolts and remove the water pump. Clean gasket surfaces and reinstall new water pump and reassemble. Refill with coolant and recheck system, top off engine coolant after it has re-cooled.

My cars interior is not being heated. I was tod that it was the waterpump, could it be the theremostat. The car is a 02 Intrepid 3.5L engine.

Okay, The water pump is more than likely okay but at this point I would not rule it out completely. One simple check to see if the water pump is moving water and that the thermostat is opening and closing is to take off the radiator cap when the car is cold. Start the car and stand at a point where you can see down in the neck of the radiator without looking straight down into it. When the thermostat opens you will see the coolant level change dramatically when the thermostat opens, you should be able to see the coolant being pumped through the coolant tubes in the radiator. IF you see the coolant level change and then see the coolant being pushed through the coolant tubes, then the water pump and thermostat are probably okay. If they appear to be working okay then the next thing is to check the heater hoses to see if they get warm. Do not grab either one while the car is at normal temp as they can be very hot. Let the car cool down for about a half an hour then see if they are both warm. If they are, then I would move to the inside of the car and check the heater controls. There may be a malfunction in them. The reason for this logic is that if the water pump is not operating properly or the thermostat is not functioning properly, Chrysler will usually turn on the check engine light indicating a problem. They have sensors in the engine that tell if the coolant is to cold or to hot (these are not 100% accurate but in most cases are). The heater controls on the other hand are not tied into the check engine light so if there is a problem there, you will have to do some digging to find the problem. If the heater one of the heater hoses is cold and the other is warm after running the engine then the heater core is probably plugged up not allowing the hot water to move through the core to produce heat.
