My 2005 Chevy Impala overheats when I start it and the front heater blows cold air.?

Question

When I drive it the temperature returns to normal, although the heater continues to not work well.  It'll blow a bit of hot air but not as hot as normal.  When I idle at stoplights, the temperature again begins to rise.  Is it the thermostat going out or is there not enough coolant/water?  Any suggestions?

? · Accepted Answer

Coolant is low and theres an air pocket in the system.

Fill up and bleed cooling system- The next part of the problem is, why is the coolant low, how long before it gets low again- you may have a problem on the rise!

Good Luck!
