Sounds like a bad thermostat. Its either stuck open or stuck closed. Get it replaced ASAP before you do damage to the engine.

    As for the faulty air bags, first check fuses under car to make sure that the fuse for the airbags are not blown. If no fuses are under the hood for the airbags, check the ones on the drivers side panel. If the fuse is blown, replace it and thats your problem. If not, then the air bag needs to be checked out at a dealership or local shop.

Heater runs hot then goes cold


Do you have a temperature gage in your instrument cluster? When the temp goes cold, does the temp gage rise? Check your coolant level both in the radiator and the coolant recovery tank under the hood, and fill as necessary. If that is OK, then check your serpentine belt for wear and/or slippage around the water pump. Lastly, if you have a temp gage and are noticing fluctuations in the reading, you may need to replace your cooling system thermostat. Good luck.

Why is my add coolant light on


your coolant light is on because there is not enough coolant in the radiator. When the coolant is hot it expands and the excess water is pushed out into the reservoir and as it cools down the water is sucked back in and so keeps the top tank of the radiator full. However if you have a leak or a faulty radiator cap the water comes out ok but instead of sucking back in water it allows air in instead. Therefore you have a one way circuit of water out but no water back in. Your coolant light is telling you to check out the fault before you over heat the engine

Mini Cooper temperature gauge goes to red zone when idle


check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling leak.so replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

Temperature gage fluctuates when driving my 1996 mazda protege


Well sounds like first start your car record where the temp needle reads, then let the engine warm up (with out driving) then rev the engine to about 3500-4000rpm a couple times does your needle move at all record then hold your rpm at 3500 for about 5-10 sec does this get the gauge to drop? sounds like you may "if not over heating at all and coolant level and circulation is good" have a circuit problem, you can test this by going to auto zone and ask for a scan to be done on your car when the plug into your OBD 2 ask them to go into DATA STREAM and then check to see what temp your ECM thinks the engine coolant is at does it match your gauge at idle and at 3500rpm if not its a faulty circuit

My heater isnt working, the temperature gage flucuates, and it keeps telling me it has low coolant even though I just added coolant


low coolant sensor is probably just dirty. cold air could also indicate n air bubble in the line. could also be thermostat. try that first.

I have a 2004 Pontiac Sunfire. When the car is in idle the air blows out hot and the Temperature gage rises and the car over heats. When the car is moving the air blows out ice cold and the temperature...


Sounds like your cooling fans on the radiator are not working. The fans are activated by a thermol switch on the engine or radiator reading the coolant temperature and an A/C switch. When the coolant is too hot the fans should activate cooling the system down. And, when the A/C is on the fans should also activate in order to cool the condensate so the A/C would work.

When you are driving, the movement of the vehicle throught he air is providing enough air flow to keep things cool and functional.

I would check the radiator fan fuse or fuses first. If those are OK I would try to run the fans with 12 volts and a ground that I supply just to see if the fan motor(s) actually run when powered. If the fan don't run when powered then the fans are bad and will need to be replaced. If the fans do run when you power them manually, then something is not allowing the power to activate, like a relay, control unit, or wiring.

It will take a little diagnostics, but it is not too difficult to chase it down.

On our 2005 Town and Country, the heater does not heat up for a long time, then it gets hot and then cold. Occasionally the temperature gage goes to warning light hot but this is about once every 3 to 4...


I assume you have checked the cooling system to ensure that first, that it is completely full of coolant (not just the overflow tank) and second that there are no leaks anywhere. Your description indicates either low coolant level and/or air locks in the cooling system. Only check coolant level when engine is cold. If it needs topping up, add coolant and then run engine at idle with heat control on full, until it reaches operating temperature, topping up as necessary. Allow cooling fans to cycle on and off a few times to ensure all air is purged from system. If coolant was low, then check regularly when engine is warm to see if you can find where the coolant is leaking. The places where the hoses connect to the metal pipes around the engine are the most likely points of leakage or a hose could have weakened and split.

If coolant level is OK and there are no leaks then it could mean a faulty water pump.

When I turn the key, the temp gage goes to full hot. even when the engines off with the key in the run position


Either the sensor is faulty (not uncommon) or the wire to the sensor has been damaged and is earthing to the bodywork.

To check, disconnect the wire connector at the sensor. If the temp gauge stays high then there's a wiring fault. If not just change the sensor. You'll have to partially drain the coolant to do so so make sure you release the pressure cap first and catch the drained coolant in a clean container for re-use. If the coolant is any colour other than a definite blue or pink then discard the drained coolant and top up with fresh coolant mix. Turn the heater in the car to cold before draining dow: this keeps the coolant in the heater core and prevents air locks when you refill the system. Also, the new sensor should come with a new seal. If not then order a new seal when you order the sensor.

I hope that I've been of assistance and that you soon resolve your problem. Don't put it off, as a simple £5 sensor protects you from a potential four figure repair bill.

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...


first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure
