Question about 1996 Buick Century

1 Answer

My engine won't cool itself down sometimes. I'm thinking its the thermostat or the sensors. When the engine gets too hot I turn on the heat full blast and it cools off. Just today I did just that but the heat didn't turn on. Sometimes it takes untill the engine is almost at hot for the heat to kick in.

    I just replaced the radiator about one month ago. The radiator was brand new and the water pump was used but in pretty good condition. Also I forgot to add that sometimes when I park my car and it cools off completely there is some kind of fluid on the ground under the engine. Could the water pump be going bad or could it be from the engine cooling down after getting too hot?

Replace the thermostat,and coolant sensor,and add coolant,and bleed all the air out of the cooling system,if this does not help,replace the radiator.

    It can be from either one,feel under the pump pulley in behind it to see if it is wet,if coolant is leaking,it will have air and cause this problem,but the coolant sensor turns the fans on,if they are coming on,the sensor is most likely fine,but they most likely will not turn off on there own,try finding the leak,and bleeding the system out

It's running cooler because the thermostat is opening too soon. As far as the heat goes, let it warm up to operating temperature, turn on the heat full blast and feel the temperature of the hoses going to the core.
1- both cool- engine not reaching operating temperature or the system needs to be bled of air
2- one noticeably cooler than the other- clogged core; you could try backflushing, or replace it.
3- both equally hot to the touch, where you can barely touch them- everything is good on the liquid end- look at your blend door in the heater box.

Audi a4 2.8l no heat


take the top off the filler cap run engine to boil. keep it full off water to the top. you will see air bubbles coming out as the engine gets hotter. squeeze the pipes on the rads to help the air come out. when fan kicks in turn engine off and leave to cool down.while you are doing this make sure the fan for heater is off but is on full heat. can have fan on number one on speed that is fine.

Most engines don't fair well under extreme heat. It's apparent you might have some electrical issue's. Your rpm's or mph arm going up and down could be faulty speed sensor would cause arm problem. I think you may have more than one problem, the car shutting off is due to engine over-heating. Check cooling system-thermostat, water pump, radiator, engine fans and coolant temp sensor and fan relay's. It could be as simple as blown radiator hose.

Low heat on buick rendezvious


Ask to see a water pump for your car at an autoparts store like Autozone or Advance. This may be a model with a relief valve inside the waterpump. If your car is one of the rare ones with this part, it may be stuck open on your car.

Also have someone check the Electric Radiator cooling fan Relay. Sometimes it can stick to run full on when it should be off. This would be a simple fix. There are also sensors which activate the Electric Radiator cooling fan Relay. If the sensor is telling the engine to cool itself too early, then the fan would activate too soon.

You can get FREE diagrams at Autozone.com and see which Relay is in the powerbox and which is by the electric Radiator fan. Then you could simply replace the relay. But the sensor, if bad, would still tell the Relay the wrong information. It would need to be replaced, perhaps instead of the Relay.

If the car seems to be have some drivibility issues in cold weather, then the temperature sensor may be failing to tell the engine that it is cold and not hot. The sensor can be stuck on the hot settings, making the electric Radiator fan work and failing to control the engine for cold conditions.

Won't blow hot air, engine heats up at high speed


If your radiator is full of water, then its probably the thermostat sticking. The thermostat is located on top of the engine, under the housing that the radiator hose goes to

Over heats new thermostat hest almosts pegs then comes down


If you replaced the thermostat I would look next at the electric cooling fan thermostat.. Its likely located in the radiator itself and is in charge of turning on the electric fans.

To check. start the car and listen for the fan next to the radiator to kick on. It should start running before the car gets over heated.

Also when the temp gets really high is the radiator hot? if not then you still have a coolant flow problem. If the radiator IS hot then you have a problem with the coolant not getting cooled. Either an electric fan/thermostat of if you have an engine driven fan maybe its clutch is bad.

Car runs hot


If it was the thermostat, it would run hot all the time. Sounds more like the electric cooling fans are not working. Either the fans themselves are not working, or the coolant temperature sensor is bad and not sending a signal to the computor to turn them on. Have the fans checked first, then go for the sensor if it isn't the fans.
