Check your heater core. You may have the heater core leaking and if it continues it will not be long before it will begin to leak inside of the vehicle itself.

What if coolant leaks when car is parked and radiator still has fluid where and why would it be leaking also what if you can smell it through the car while driving with out heat or AC on?

I would check the radiator coolant bottle for cracks and inspect any hoses to bottle.


Why is your radiator fan light on in your mercury cougar?

The radiator fluid is low or you parked the car at am angle.


Why does a 1999 Saturn heats up to half way on temperature gauge then cools off to quarter when parked idling?

The 1999 Saturn S-Series engine heats up the coolant, the thermostat valve opens and the coolant circulates between the radiator and the engine. Then the radiator fans turn on to cool it back down. The fans are also turned on when the air conditioner is turned on to aid in cooling the radiator and the air conditioner condensor.


Will a bad thermostat effect the operation of the radiator fan on an SL1?

some of the saturns have a thermostat that also controls the fan, so if the thermostat is bad the fan will be inoperable...others have a separate sensor..if the thermostate is the fan controler it will have a wire coming off of it, otherwise look for a sensor that goes into the water jacket or block of the engine, it will also effect your water temp gauge.Answersome of the saturns have a thermostat that also controls the fan, so if the thermostat is bad the fan will be inoperable...others have a separate sensor..if the thermostate is the fan controler it will have a wire coming off of it, otherwise look for a sensor that goes into the water jacket or block of the engine, it will also effect your water temp gauge. AnswerYes. The Thermostat controls the flow of coolant through the radiator. The fan controlls the flow of air across the radiator. They both work together to assure the engine is allowed to reach normal temperature and not get too hot. A working thermostat restricts flow through the radiator until the coolant in the engine reaches 195 F. It then opens just enough to let the proportion of coolant being cooled in the radiator control the engine temp to 195. The radiator fan is temperature controlled, it comes on when when hot and cycles off when it cools down. Normally it is off at highway speed because plenty of air is flowing anyway. When parked or in city traffic it cycles on and off, coming on more when the vehicle is standing still or moving very slow. The most common failure mode for a thermostat is to fail open. In that condition the engine will take a long time to warm up. (The first thing most drivers notice is it takes a long time to get heat in the passenger compartment.) With the thermostat stuck full open the fan will seldom run. It just won't get warm enough to turn on, unless you are towing or climbing mountains on a hot day, or come to a sudden stop after driving on the highway. When parked or operating in city traffic it will not come on as often as it would if the thermostat was working.


No oil leak on your 98 gmc 5.7 motor where is the oil going?

Did you mean the lubricant or the fuel ? May be it is leaking while you are travelling and when parked, you can't discover the location of the leaking which may be a little hole or a defective oil retainer.

No there is currently no laws regulating a vehicle with an oil leak on a public roadway.


Your 2002 Mazda 626 4cyl keeps over heating when driving down the street not even 1 mile But when left to idle in park it will not over heat what could this be?

I'd start by checking the coolant and look for leaks. I'd go further by seeing if the thermostat was good. You can grab hold of the upper hose on many cars and feel if water is flowing or getting hot. Is the fan working when your parked? Is there anything in front of your radiator. Is the water pu mp working or leaking. yes this model has a big problem. i have worked on many and found that the radiator blocked as they were built with the cylinder head restricting the flow, so at speed it WILL OVERHEAT SO just do a good radiator clean,then reverse flush the motor with head every 12months or so.bazza


What causes a 1992 Crown Victoria to drop at the back when parked?

Do you have air suspension? If so, then something is leaking. Check out Strutmasters, in the net. They have solutions 4 u.


Why would a 1999 intrigue run hot only with car in park and holding the motor at 2500 rpm if it has new thermostat?

The thermostats function is to hold water in the engine or the radiator to maintain proper running temperatures, most thermostats open around 180 to 190 and are fully open at 205 to 215. when the coolant in the engine reaches thermostat opening temperature, the coolant flows from the engine to the radiator sending hot coolant to the radiator and cooler liquid to the engine. this is the cycle that maintains the proper temperature. 4 things will cause the system to not work as you described. 1: The radiator has dirty fins not allowing good enough air flow from just the fans alone. 2: Your water pump is not operating efficiently enough to flow the coolant through the system 3: Your fan is not working. with the car parked the only thing cooling the coolant in the radiator is you fan if your fan is not working or not working properly it will not pull enough air through the radiator to cool effectively, and this can be adversely effected by solution 1 or 2 above as well. 4: The thermostat you purchaed is defective.


Why can I smell antifreeze in my car?

antifreeze smell inside car means that there is antifreeze leak somewhere. first check for wet spots under car when parked after running.if anti freeze is leaking from engine it will pool on the ground next check to see if heater core is leaking. that is usually the problem. if heater core is leaking, replace it


Why does your 2003 Dodge Stratus keep overheating while parked?

Check to see if your electric fan turns on. Else check coolant level and replace thermostat.


Cause of coolant leak in 1970 440 roadrunner?

First, where is it leaking. If you smell coolant inside the car, the windows mist up with a "slimy" film, or the front carpet/floorboards are wet, you likely have a bad heater core-the "mini-radiator" under the dash that provides heat and defrost. Does the car leave green puddles where it is parked? It could be leaking from the radiator, hoses, or water pump-you have to look for green (or orange, depending on the type of coolant used) drops or dried residue-a healthy car should have none. If there are no drips or puddles, the car could be leaking coolant into the cylinders via a leaking head gasket. Usually this is accompanied by poor performance and white "puffing" from the tailpipe when the engine idles. Another common cause is a bad radiator cap, if the coolant bottle shows signs of cooland coming out of the overflow drain, a cap with a weak spring could be allowing coolant out of the engine when it shouldn''t. Finally, ensure the engine isn't overheating, as this can cause the overflow condition just mentioned.
