Hello Everyone, first time poster, long time reader.
My 2010 3.8L Town and Country with 116,000 miles has me confused. The Heat coming out of the vents gets up to 240 degrees on full heat! The temp gauge never goes over halfway, but if the heat coming out of my vents is 240 degrees, doesn't the motor temperature have to be 240 degrees also?
A couple more facts, I believe the thermostat works, because my top radiator hose is measuring 175 degrees. I would like there to be more pressure on the top hose though, is seems pretty limp when the car is running, I thought these things were supposed to have some pressure while the cooling system is hot.... The thermostat housing measures about 190 degrees and the top of the engine right next to the thermostat housing measures about 215 degrees (when measured by a temperature gun) The engine has been smelling slightly hot, but not too bad. I recently did a coolant spill and fill. I put in the correct G05 antifreeze and I used an air lift system to burp the air out of the system while both the front and rear heaters were on.
I don't know what the next step is, 240 degree heat seems way too high even though the rest of my gauges seem in range.
Do you guys have any ideas? What temperatures do you guys have with your heating system?
Thanks!
Ben B.
