This isn't an SL2, this is an L200. The cooling/ ac condenser fan module is located at the driver's side front under the hood near the radiator. The module has a series of relays in it soldered to a circuit board. These relays can become stuck closed and cause the fan to stay engaged even when the car is off. You can try smacking the top of the black box cover of the module which is mounted vertically to possibly make the relay(s) release, but you need a new cooling fan module. On the side of your thermostat, we had a bit of trouble bleeding the air from these models when servicing the cooling system, so you may want to elevate the front of the vehicle and add a coolant funnel adapter with extra coolant in the funnel adapter to aid in burping the air or purging the system. BTW that particular year had a poorly positioned thermostat at the rear of the engine near the firewall. I pity anyone trying to do this job for the first time not knowing the procedure. I am referring to the ECOTECH 2.2 L 4 cyl. Perhaps air pockets are the problem. Then fan is definitely a problem. If you are unfamiliar with either the Coolant Funnel kit , burping air from a cooling system, or the cooling fan module, seek out a trained techinician to make the repairs.

Did you remove the thermostat, fill it up with coolant, then put the thermostat back on, spring side TOWARDS the engine ? Then fill up the radiator , close up the system, start the car, put the heater on full hot, then add coolant through the reservoir. Good luck.

    yes, remove both the coolant cap and thermostat, fill up both, then repkace the thermostat. The engine will get an air pocket if you dont fill it first.ou

I have a 2006 dodge grand caravan, when the car is in driveway idling the car wont heat up but as soon as you start driving the car, the car heats up normally. Should i replace the thermostat or is it...


The reason for replacing the thermostat is improper cooling - not heating. The purpose of the thermostat is to shut off the flow of coolant through the engine allowing the temperature to build. When it reaches the temperature it wants the thermostat opens and allows coolant to flow to maintain the proper temp. Dodge Caravans have a track record for maintaining a low temperature until the engine is at higher rpm. While it is inconvenient in cold weather it it not bad. However, you want to check that your radiator fan is shutting off when it is cold. A fan that is staying on when it shouldn't could cause the temp to stay cooler.

Fan stays on after turning off car relay switch location 


when you shut the motor off and it is hot the fan will come on until a certain temperature is reached and then shuts off. this is to keep the engine from being damaged by excessive heat. it is controlled by a temperature sensor which is normally on the engine block near the thermostat housing.

No heat in car and temp gauge rises while driving but stays half


With engine cold, remove rad cap & check level in rad. Top it up if needed to 1 or 2 inches from top. Start engine, turn heater on (not defrost) and observe coolant level as engine warms up, add if necessary. Radiator fan should be off, and only come on when engine reaches normal operating temperature, for a short time, then shut off again. Let it run until that happens about 3 times, then put rad cap back on. If temperature gauge climbs up over normal toward hot, too much, shut it off. Do you now have heat? Is rad fan acting as I described? Let me know.
