How do I change my thermostat in my '05 Impala 3.4 V6..I changed the water pump so I need the thermostat info

Question

Hot Coolant Temp light came on. So when I turned the heat on full blast, nothing but cool air came out. If I'm not mistaken that means the thermostat needs to be replaced. She was leaking fluid, but I changed the water pump and that stopped. Soooo, any help I can receive will be greatly appreciated.

Answer 1

On this type engine (3.4) the coolant system has to be bleed while refilling with replacement coolant.   If you still have a problem, visit www.mygmlink.com
