possible head gasket problem this engine was famous for it.
If it is a V6, the cam belt, water pump, spark plugs, coolant, and thermostat, should have been replaced at 110,000 miles. If you have not done so, know that this is an interference engine. If the belt breaks you will have engine damage. If it is a 4 cylinder the spark plugs, coolant, & thermostat need to be replaced. Have brakes and suspension inspected.
Defective radiator cap?Fan temperature sensor defective?
If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing. As the water pump should be replaced at the same time as the cam belt every 90,000 miles, you should also replace the thermostat and coolant.If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing.

Low coolant or stuck open thermostat.Low coolant or stuck open thermostat.
The original coolant would have been "DexCool". The cooling system should be flushed and coolant replaced every 5 years or 100K miles if you use DexCool.
Try replacing the thermostat.
Have you checked the thermostat? How many miles on motor? Ever changed coolant? Possible water pump issue?
Possibly a clogged or restricted radiator Low coolant Cooling fan not working Thermostat not opening fully
You mean belt- every 65-75K miles, along with the tensioner, thermostat, coolant, rollers, and serpentine belt.
Change it every 100,000 miles on the 4 cylinder and change it at 105,000 miles on the V6 at the same time you have the cam belt and water pump replaced.
First, where is it losing all the coolant ? Is it losing the coolant in the engine, or on the outside of the engine ? You must establish this first. What was the problem before ? Is the coolant leaking from the out side, like near the water pump, or from the large tube that goes into the water pump from the rad. hose ? Is there a problem with the thermostat ? When you replaced the pump, and put in the O- ring, did you put some silicone on the O-ring to help it seal ? Is it leaking from there. Check all the hoses and clamps and the rad. Good luck.
Possibly change engine oil/filter and any other maintenance that is due. At 105,000 miles you MUST replace the cam belt, water pump, thermostat, and coolant. Also replace the spark plugs if they have not been replaced. Replace the brake fluid if that has not been done.
