Default Heater not blowing HOT!???

I have a 93 sc4 and just had the thermostat replaced yesterday. Now I have no heat coming thru my vents, even with the temp on MAX HOT after driving for 30 min, still no heat. I feel like I can smell the heat but the temperatuire is not there. Anyone know what may be causing this problem?

Try doing WOT.
If you get heating then, it's probably your water pump.
If not, could be your heater core.

Make sure you have coolant in the radiator, If you just replaced the thermostat...this could be the problem.

If there is no water going past the coils, then the hearter wont work correctly.

Default No Heat

Sounds to me like you have an air lock in your cooling system
Make sure heater is on, engine is running radiator cap off.
Remove filler cap above themostat housing and add coolant untill it overflows.

Hope this helps.
