What should I check if I have a 1999 V6 galant that overheats while idling it is not the thermostat or fluid levels?

Engine overheats
When a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system ( air trapped in the system can cause overheating also). Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps will solve the problem.
Check your electric fan.

Truck overheats 2 minutes after start then runs FINE any ideas?
You must check the coolant level in your radiator and reservoir. Low coolant levels can lead to overheating. If it's low, you may have a coolant leak that needs to be repaired. Good luck!
Is the engine thermostat part of the emission system?
No, but the temperature senders are part of the emission system. If the thermostat malfunctions, the emission system will not operate at optimum levels.
Why is your engine overheating?
There are few reasons why a car overheats. Coolant levels are to be assumed as in the correct levels. If that is the case, you have a flow issue or a heat removal issue. If the pump is running (rarely the issue) then the flow issue could be from your thermostat sticking (a normal failure mode). The second possible issue could be that the radiator itself is plugged and unable to remove the heat. This shows up as a slow steady heating of the system and could take many miles to overheat.
How do you replace the thermostat on a Chrysler Pacifica?
To replace the thermostat on a Chrysler Pacifica, first locate the thermostat housing just behind the alternator. Remove the two bolts holding this on, then remove the old thermostat. Replace with a new thermostat and thermostat gasket. The put the bolts back in and tighten down. Make sure to check the antifreeze levels after this project.
Why would your heat stop working in your 1992 Pontiac grand prix?
coolant levels or the thermostat
Why does a car blow cool air while idling?
Blowing cool air while idling & the water pump is not moving very fast is a key indicator of low engine coolant levels. Add some anti-freeze/water and likely you'll have warm air all the time.
What would cause 2000 Chevy s-10 fo overheat and fluid levels are full?
check your thermostat
Can bad driving cause oil and coolant levels to go down drastically?
Hard driving can cause an engine to use oil, but not drastically. Coolant level should not be effected unless the engine overheats.
Heater starts to turn cold when at stop light - what causes that?
The #1 cause of cold air from the heater when the car is stopped, or the engine is idling, low engine coolant levels.
How do you fix an overheating 89 Honda prelude that had its radiator thermostat replaced already but still overheats?
Cooling fan not working? Water pump not working Radiator plugged Hoses collapsing Airbound Cooling fans do work. Like when she is on the hwy, she's fine. Stop & go stuff really gets to her. Also, she may run fine one insance, then if I shut her off and restart her the overheating begins, thenEngine overheats When a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage.

Why No heat in a 1989 Ford Mustang?
low coolant If your coolant levels are fine the next thing would be is to install a new thermostat.
What make your car run hot?
All sorts of thing can.. Low oil, low coolant, blocked radiator, stuck thermostat, running too lean on fuel... If it just suddenly started to do it and the levels are ok then check the thermostat.
