Either the temp sensor is bad, or the relay is bad. or the fan motor is bad. Or you have a blown fuse.
Look for fuse first.... To test if fan motor is bad disconnect the connector to the fan and jumper it to the battery.if it spins it's good. the other two. use a component locator to find their location and replace. they are inexpensive. Temp sensor is in the cooling circuit (radiator...maybe next to thermostat) the relay will be in a fuse box under the hood.

SOURCE: my car overheat when im using the car aircon,it

The cooling fan should run continuously when the A/C is on. If it does then I suggest you drain and flush the cooling system, and replace the thermostat. Fill it with a fresh supply of a 50/50 mix of antifreeze and distilled water.

If you have a test light then you can check to see if you have power to the fan. You can buy them at any auto parts place. Just take the ground and clip it to metal somewhere close to the fan. Then you can take the test light and probe the wire. See if you have power on either wire. But the engine has to be running, so you have to be careful. If you don't have any power to the fan, then it is the fan relay or the ecm. I would suggest replacing the relay first. It is quite a bit cheaper.

Water Pump leaks from the front end of the Wagon.

follow this steps and fix it. God bless you
  1. Determine the Reason for Water Pump Failure
    • 1 Repair a water pump by checking your car for a failure in the bearings. You can test for bearing failure by seeing if there is any play in the shaft that is connected to the electrical fan blades, as well as the drive pulley to the pump itself.
    • 2 If you notice any free play in the shaft or the pulley, you will need to take the pump apart and replace the bearings.

    • 3 Determine if the water pump failure is due to a leak in the casing. Examine the water pump housing for leaking or water stains in the drainage hole next to the pulley.
    • 4 If water is dripping from this hole, then the seals inside the pump need to replaced in order to repair the pump.
    Remove the Water Pump for Repair
    • 5 Allow the engine to cool completely before removing any part of the cooling system. Never open a radiator cap or plug while the engine is still warm.
    • 6 Disconnect the car battery. This will prevent the electrical fan from turning on while you are under the hood.
    • 7 Drain the radiator of all fluid and disconnect the radiator hoses. Collect the fluid with a plastic container and keep it in a safe place until you are ready to put it back into the radiator.
    • 8 Remove the fan assembly. This will include the shroud, the fan and the fan belt. Disconnect the electrical leads for the fan.
    • 9 Remove the pulley for the fan belt as well in order to have access to the water pump.
    • 10 Use a socket set to remove the water pump from its engine mount.
    • 11 Open the housing for the water pump and replace the seals or bearing as necessary. Some auto parts stores carry repair kits that have both the seals and bearings for specific types of water pumps.
    • 12 Reassemble the cooling system by replacing the water pump, pulley, fan belt, fan assembly and radiator hoses. Refill the radiator with the fluid.
    • 13 Start the engine to see if the water pump repair was successful. Check for leaks before you take the car out on the road.

Coolant for solara wagon 6 cylinder

coolant is for the cooling system,the cars engine must be cooled, there is a radiator , hoses and fans. the coolant is also used to supply heat to the inside of the car in winter conditions or cold days.The radiator which is bolted on the front of the car stores coolant (antifreeze) the coolant is then pumped through the engine by the waterpump, there is a thermostat that regulates the coolant flow. when the coolant in the engine reaches a certain temp. 190 degrees the thermostat opens and allows cooler coolant to enter the engine to keep it from overheating, the coolant that comes out of the engine then flows through the radiator and the fans are turned on by the computer to cool the coolant as it flows through the radiator. this goes on and on to keep engine operating around 170- 190 degrees,If the coolant does not cool the engine then engine damage will occur.
coolant is also used to keep for freezing in cold temps, the coolant is mixed 50/50. half coolant and half water. if water was used it would freeze and in the summer it would boil and is not a good cooling source.hope this is helpful.

I have a 1990 Jeep Grand Wagoneer that run hot when the truck is park are not moving so please

first check thermostat. when jeep is cold take out thermostat and see if you can move any parts . It might be frozen , if its good, then your fan is not providing enough cooling through the radiator to cool engine. if the fan is working properly, then your radiator fins are clogged and u need a through flushing.
