So my car keeps overheating. I have changed the radiator and thermostat. Ill drive from bout 5-10 miles fine without the temp needle going up. The itll go up. When I used to have the heater on full blast it would lower my temperature. But now its blowing cool air and the temp meter is goin all the way up. Also when I hit the gas pedal it starts raising the temperature. I do have an intake system that is touchin a motor mount is that bad? Nd also when I open the hood there was coolant everywhere on the top inside of my hood.

Umm to that question I do not know my dad did the radiator change. How would you do a bleeding for a radiator? Could it be the water pump or timing belt?

It could be water pump, thermostat or engine itself but never the timing belt.

COOLING SYSTEM BLEEDING
1. Set heater controls to maximum heat. Fill cooling system with a 50/50 mixture of coolant and water to bottom of filler neck. Loosen bleed bolt, located on thermostat housing.

2. Tighten bleed bolt when coolant flows from bleed bolt in steady stream without bubbles. With radiator cap off, start and operate engine to normal operating temperature (fan comes on at least twice). Add coolant as necessary. Install radiator cap.
