PONTIAC GRAND PRIX COOLANT PROBLEM

2007 Pontiac Grand Prix • 79,000 miles

Helio, I am wondering what I need to do. My 07 Grans Prix is blowing out cold air. After about 30 min. Its blowing the heat normal. What could be wrong? With my weather being fall and not below zero the heat should blow faster than that right?

Check to make sure the coolant is full. If it is, check the thermostat (make sure the engine is warming up to normal operating temp).
