Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello. Did you have heat before performing the cooling system repairs?
Alright. First, have you checked the coolant level to make sure that you have enough coolant to flow through the heater core? I have seen it multiple times where theres not enough coolant to flow through the heater core in the system, but enough coolant to keep from overheating. If there's plenty of coolant, then check to see if the heater core hoses going into the firewall are both hot, or if one is hot and one is warm, cool, etc. Please let me know what you find. I'll be around. Thanks
How was your coolant level?
