Bought this 3 months ago. Car started blowing white smoke and idling rough a month ago. Tried bars stop leak fix for possible blown head gasket. No more white smoke. Bars did clog up system but flushed it out several times (heater core as well). New thermostat 3 weeks ago (prior to bars), new thermostat yesterday after complete system flush. (10/27). Temperature is all over the place now (165 to 253). Get heat for about 10 minutes of operation then cold air. Coolant is bubbling in overflow tank after highway drive of 10 minutes. (When system was refilled it was done from top radiator hose first then over flow tank). Bottom radiator hose is hard and not hot. Heater hoses are both hot. Upper radiator hose is hot. After car sits for 5 minutes the bottom hose is then hot and the over flow tank is empty. All hoses are then flat. (Filled tank and burped system to cold) A/C works just fine. Took apart climate control system; actuators and blend door. All operating normally. Checked all fuses none blown. The car has no leaks under the front end. Can anyone help me nail down possible other things I may have over looked?

Hi,

Sounds like you still have restrictions and air pockets. More than likely you still have some of that stop leak floating through the system.

The service manual is specific to say not to use chemicals due to the dex-cool coolant that is used. This can cause issues and potential clogs.

I would suggest separating the system into three sections and flush them individually. Heater core, engine block, and the radiator. Just flush each until the water is clean and then when you fill the system, jack up the corner of the vehicle that has the fill cap. This will cause the air to work its way to the highest point and come out.

Let me know what happens. Thanks
