New radiator?

[prixfreak]

I have an 02 grand prix gtp. I've replaced the supercharger gasket the lower intake manifold gasket the thermostat and ects, as well as a few other related parts. Now my car is running hot but the heat just blows cold air. I had a coolant flush done in a shop about a year ago but could I need another one? Could the radiator be bad? Help! Fed up with coolant system...

Have you looked at the heater core? I mean, if the gauge on the dash is showing that it's heating up then you have the heat, you're just not getting the heat to the vents.

When did the lack of heat start? You could have put air into the system and it's stopping flow to the heater core. Could also be that the mechanism that directs air through the heater core is not working and it's just pulling outside air in.

Bleed the coolant, you might have air in the system. If that doesn't help, it's probably the heater core.
