How do I reset my car thermostat?
Start your engine and let it idle for 10-20 minutes. From a cold start, your vehicle’s thermostat will stay closed and you won’t notice any coolant flowing into your radiator. Leave the vehicle running for about 10-20 minutes so it can reach its optimal running temperature.
What causes a new thermostat to fail?
Once the coolant engine reaches proper operating temperature, typically 180 to 200 degrees, the thermostat opens up and allows the coolant to flow through the engine. Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.

Your mechanic needs to do a combustion test. This is important to find out if there are any exhaust gases in the cooling system. The water pump is all solid steel so unless it hasn’t had regular cooling system service it’s unlikely the water pump. They should also do a leak down test.
Why is the exhaust not sweet in my Subaru Tribeca?
Or run hot. This is why there is no sweet smell in the exhaust. The combustion test is there to show the exhaust getting into the cooling system. After ordering all the new parts ( water pump, thermostat, timing chain, radiator, gaskets etc) the cylinder head is porous and can’t be rectified.
