armin922 Posted October 10, 2008 Report Share Posted October 10, 2008 What do u think this could be? Someone told me to check the thermostat. But i dont know if this is the problem. Could it be the heater core? If so it will be a PITA!! But yeah, like it says, it doesnt blow hot air at all. Quote Link to comment Share on other sites More sharing options...

Cordell Posted October 10, 2008 Report Share Posted October 10, 2008 First thing to check would be your coolant level. Most of those cars have quite a few coolant lines behind the engine and are prone to leaking on an older car. One of the first things you notice with a coolant leak is the lack of hot air.

Dave1647545494 Posted October 10, 2008 Report Share Posted October 10, 2008 look at the heater hoses behind the motor right before the hoses connect to the heater core there is a little bypass hose this bypass allows debri to collect in the heater core and then the water flows through the bypass instead the fix is to remove the hose assembly flush the heater core with a garden hose and then make new heater lines out of bulk hose this elimnates the bypass and no longer allows debri to become trapped in the heater core. this is alos assuming you have already checked that the motor gets up to operating temp and the thermosat and fans function properly hope this helps Quote Link to comment Share on other sites More sharing options...
68camaro Posted October 10, 2008 Report Share Posted October 10, 2008 Look in the reservoir and see if it is dirty. If it is the heater core is plugged up. Quote Link to comment Share on other sites More sharing options...

armin922 Posted October 11, 2008 Author Report Share Posted October 11, 2008 ok, thanks. Ill check the resevoir to see if its dirty and check the hoses. I hope its not the heater core, ive never taken apart a dash before let alone a heater core, so this might not go well! I appreciate it.
