2003 Stratus R/T just had the thermostat, thermostat housing, and the water pump replaced. Now it runs cold and is sluggish in 1st and 2nd, and the heat is underwhelming. Plugging the suction hose on top of the engine until it nearly kills seems to temporarily solve the problem.

Why do you need to replace thermostat.? Is it not getting hot enough via the heater,or is the engine water boiling? Its usually at the end of the bottom hose nowadays,youll see a round housing,two or three bolts.Drain the water first,or undo the bolts,engine cold,and catch the water.Replace with an original thermostat,and double check the sealing ring is in place on the new one.Refill radiator.Run engine,check water level later,with heater on hot
I could not give you the going rate for your local shops, but if it is like most vehicles it should not cost more than an hour labor and the thermostat should only be a couple of dollars. You can do the job yourself. The thermostat is usually located at the end of the radiator hose that goes into the top of the water pump/engine. Thats the thermostat housing. It is usually held on by two bolts. You just take the radiator hose off the housing, undo the top bolts and the housing should come off. Scrap the old gasket off of the housing and the water pump/block with a razor , pop in the new thermostat and gasket then reattach everything and you should be good to go.
Follow the top radiator hose to where it connects to the engine it will be connected to your thermostat housing. Disconnect the radiator hose and unbolt the housing your thermostat will be behind the housing.
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!
