How can I tell if my Dodge Ram 1500 is overheating?
Dodge Mechanic: sprinkles08, Chrysler/Dodge/Jeep master tech replied 10 years ago Sometimes it will. This will be much easier to see on a cold engine. If you start the engine cold with the radiator cap off watch closely for any bubbles and see if you can smell exhaust coming from the radiator.
Can a thermostat be installed in the wrong direction?
Answer: A thermostat installed backward will cause the engine to overheat quickly, similar to a thermostat being “stuck closed.” Therefore, always double check that the thermostat is installed in the correct direction, and if equipped with a jiggle valve you install it according to the Factory Service Manual.
What should coolant temp be on Dodge Ram?
As most of the country we got really cold & once again my heater was not blowing hot air. Coolant temp was bouncing between 185-210. Truck is a 2016 2500 with just over 50k on the 6.4.
What kind of thermostat does a Dodge Ram have?
I bought a Stant 46792. It says it is a 203 degree thermostat ( I believe that is factory spec) but my truck seems to sit around 195 mostly but sometimes dips to 192 and up to 199. This is all from the digital menu screen.
What should the temp be on a Dodge Ram?
The truck used to average 13l/100 and for the past year it seems to be around 15l/100. I doubt this new thermostat issue will fix it but any possibilities I can cross off the list. Wild one likes this. The actual opening temp of the thermostat could vary 3-5 degrees from the actual listed temp.

What happens if your car thermostat is too hot?
If a car’s engine is too hot, it can actually warp and become damaged. But, when it’s cold, it doesn’t run efficiently. So, it is important to keep the engine at the right temperature, which is where the thermostat comes in.
Why is the engine thermostat in the closed position?
The flow of coolant does not cycle through the radiator unless it is hot and needs to be cooled. When an engine is cold, the radiator fluid is cold, so the thermostat is in the closed position. When the engine starts up, and the coolant warms.
Where does the thermostat housing meet the radiator?
The thermostat housing is right where the radiator hose meets the engine housing. It looks like half of a metal baseball. When the thermostat becomes stuck, it is reasonable to simply replace it. Also, when the thermostat housing is removed, the housing gasket should be replaced even if you’re just checking it.

Why does my LS1 over heat and run?
Thermostats usually locks up in one position (closed or open) So it just over heats or runs to cool. Check the air dam down low under the fascia too. If that is damaged, the air will not be funneled into the radiator. Edit: Just read your whole post. The air dam doesn’t come into play until the car is moving.
What should I do if my car thermostat is stuck?
Watch the thermometer. When the temperature rises to the number you recorded in step #6, the thermostat will start to open. If it does not, or if it doesn’t open until reaching a different temperature (hotter usually), then the thermostat is bad and should be replaced.
What happens when the thermostat does not open?
When the temperature rises to the number you recorded in step #6, the thermostat will start to open. If it does not, or if it doesn’t open until reaching a different temperature (hotter usually), then the thermostat is bad and should be replaced. If it opens at the designated temperature, then the thermostat is just fine.
