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.
What else can I help you with?
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!
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.
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.
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 does your Ford truck ac not cool when engine idling?
If your Ford truck's AC isn't cooling while the engine is idling, it could be due to a few reasons. The most common issues include low refrigerant levels, a malfunctioning AC compressor, or a clogged condenser. Additionally, if the engine is idling too low, it may not provide enough power for the AC system to function effectively. Checking the refrigerant levels and ensuring the compressor is operating properly are good first steps for troubleshooting.

coolant levels or the thermostat
What causes your fry-master deep fryer to overheats and shut down?
A fry-master deep fryer can overheat and shut down due to several reasons, including a malfunctioning thermostat that fails to regulate the temperature properly. Additionally, inadequate oil levels can cause the heating element to work harder, leading to overheating. Clogged filters or sediment buildup can also restrict heat dissipation, causing the fryer to overheat. Regular maintenance and monitoring of oil levels can help prevent these issues.
What are the key differences between an RH and an RC thermostat?
The key difference between an RH (relative humidity) and an RC (cooling power) thermostat is that an RH thermostat measures and controls the humidity levels in a space, while an RC thermostat controls the cooling system to maintain a desired temperature.
What is the difference between a thermostat and humidistat?
A thermostat is a device that regulates temperature by turning heating or cooling systems on and off. A humidistat, on the other hand, measures and controls humidity levels in the air. While a thermostat focuses on temperature control, a humidistat focuses on humidity control.
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.
Why does my window AC keep freezing up?
Your window AC may be freezing up due to a dirty air filter, low refrigerant levels, or a malfunctioning thermostat. It is important to regularly clean or replace the air filter and have a professional check the refrigerant levels and thermostat to prevent freezing.
Why there is no fluid coming from the radiator to the thermostat hosing?
If there is no fluid coming from the radiator to the thermostat housing, it could be due to a blockage in the coolant system, a faulty water pump, a stuck thermostat, or low coolant levels. It is important to investigate and address the issue promptly to prevent overheating and potential damage to the engine.
