changed out thermostat but still overheating . blows back fluid real soon after starting. how do i completely bleed system. maybe that is the problem thanks

Sounds like you could have a head gasket problem. The system self bleeds, here are instructions to fill coolant and a link to buy a combustion tester to check for a blown head gasket. Let me know if you have more questions, thanks.

If it was a head gasket problem wouldn't it start blowing back right away and wouldn't I be able to see exhaust vapor coming out and be able to smell it?

Not always, it depends on how bad the leak is. This vehicle uses an aluminum block with steel sleeves in the cylinder bores. When overheated severely, the sleeves can move in the cylinder bore and allow antifreeze to leak from the cylinder cooling jackets. If it passes pressure test and combustion test then I would start checking for hot/cold spots in radiator which could indicate it is clogged. Let me know how it turns out or if you run into questions, thanks.
