Hello! Thank you for your inquiry. My name is XXXXX XXXXX I will be assisting you...When you stated it has no heat, were you meaning interior heater?
With the thermostat, you install it in the same direction as the one that was removed and insure the hole on thermostat flange is mounted upwards.
yes it has no interior heat and yes i believe i replaced the thermostat correctly it has overheated to the point of not starting and when it attempts to start there is a nocking noise from the lower half of the engine
also i left it runnig
Alright, first thing is this engine does not need to be run or could lead to catastrophic failure. You either have a restriction or bad water pump.
also i left it running for an hour and touched the radiator hose and it was cold to the touch
Due to the vehicle having no interior heat I believe the water pump itself has failed.
Not cycling the coolant through the engine and rest of cooling system.
The water pump is inside the timing cover driving by the timing belt.
where is it located on the dodge journey
It is inside the timing cover and is driven by the timing belt.
if i replace that and still continues do u have a second theroy
The only thing other than the water pump it could be is there is a bad restriction in the cooling system. The most likely places for a restriction are the radiator or the heater core due to small passages within them. The heater core being restricted wouldn't cause an overheat condition but would however cause no heat to the interior of vehicle. So your most likely cause of restriction is the radiator.
i will try to replace those things and go from there thank you for your time and knowledge
No problem at all! If you need any further help or information please don't be hesitant to reply. I will be glad to help!
I found a plastic t that was cracked letting all the coolant out it was not the thermostat nor the water pump thankfully
