Question about 2002 Dodge Stratus

Engine runs hot on 2001 Stratus R/T 3.0L V6

I have recently replaced the radiator, flushed the coolant system and replaced it with new coolant, and intalled a new thermostat. I have a 2001 Dodge Stratus R/T with the 3.0L V6, manual transmission and 100,000 mi. The Temperature gauge fluctuates between normal operating temp (in the middle) to almost overheating (near the H, but not at H) once the engine heats up. It will sometimes stay near H and sometimes not. The cooling fans cycle on and off like they are supposed to, sometimes they turn on very high though. When i open the hood with the engine running, the radiator cap feels cold to the touch, also both upper and lower hoses are cold. Could this be a water pump issue? Also, would a different temperature thermostat could have caused this? I think i replaced the 170 degree one with a 180 degree. Also, could i check if the temperaturee gauge is bad?
Any answers or comments would be helpful, thanks!

Hello, as previously suggested by my collegue it appears you have an air lock. Have you tried parking the vehicle on level ground, from cold with radiator cap off start the car and leave it idling. Make sure the fluid/coolant levels are o.k. and let the engine reach operating temp. Keep some warm water handy and watch/listen the water/coolant system (Keep a safe/sensible distance from radiator) hopefully after a while the system will bubble and boil up let it settle for a few seconds and then top up with very warm water do this until it hopefully stops belching out of radiator. Replace cap and hopefully top and bottom hoses will be warm. Oh! nearly forgot keep all heater controls on hot with blower on full..(Inside the vehicle)
Finally I'm not joshing but is the thermostat in the right way round and functioning correctly? to test drop it in some boiling water it should open almost immeadiatly.
sorry for the epic but I'm here to help and hopefully save you time and money.
Good luck and a Happy New Year to you and your family!

Will not have a thermastat make suv overheat its 2001 ford escape


No.
Leaving the thermostat out will not make the engine run hot.
Some possible causes are low coolant, faulty water pump, or leaking head gasket.

flush and drain your radiator and put new coolant and see what happens then if oil shows up again replace radiator because the transmission coolant line runs to the bottom of the radiator so it might be a problem there

1994 Chevy Silverado temperature guage shows hot


Flushing the radiator, replacing the radiator cap, adding new coolant, replacing the sensors and a new thermostat solved the problem. Probably didn't need to do all of these things - but since we just purchased the truck, and given the fact that is probably hadn't been done in a while, we chose to do all of these things (which really didn't cost a whole lot), it's running like a charm now.

Heater not blowing hot but engine not overheating


The coolant thermostat needs replaced or you need a coolant flush. Heater cores (in the dashboard) often clog and stop warm coolant from circulating into the heater. A coolant flush would cure this. Flushes usually run from 70 to 90 dollars to have done at a service shop.
