Q: Its running hot even when I changed my water pump and thermastat

asked by on

My 07 dodge nitro was running hot so I had my water pump changed and thermostat fixed and its still running hot

My car has 137 miles.
My car has an automatic transmission.

There are several possible causes when it comes to an overheating issue. A water pump or thermostat are definite possibilities, but there are still quite a few other possibilities. An air pocket in the cooling system, a clogged radiator, or the one I see the most, a cooling fan that isn’t functioning properly. A vehicle with 137,000 miles (I’m assuming you meant 137,000 and not 137 as stated above) is at a point where sludge and scale can build up in the cooling system and begin to hamper the cooling systems’ performance. Checking the cooling fan performance would be where I would start, in order to rule that out before starting the diagnosis process, then I would suggest pressure testing the cooling system to verify that are no leaks to begin with, and then flush the system. If you feel you could use a hand with diagnosing what’s going on, or need some help with the repairs, I recommend consulting a certified mechanic, like those available at YourMechanic.com.
