I would check the coolant level in the radiator and oreservoir to make sure you don't have an air bubble trapped.

Why does the heater blow hot air when I drive after its been idling for 15min and not during the idle when it reaches the 100 Temp?...(it blows cold air in idle)


Firstly, a thermostat that opens quicker will not give you better heat. Your heater core may be partially plugged causing a low flow issue. Another area to check would be the water pump impeller for corrosion or slipping on the shaft. Does the vehicle's cooling system operate well otherwise?

Heater blows cool warm air idiot light says it is hot


Engine temperature is too hot. Better not run it till you find the problem, or you may need new head gaskets. Try changing thermostats, flush and refill with correct mixture antifreeze and water. If still overheating, get it to a shop for diagnosing.

2001 olds silhouette engine overheats


Time for Intake Gaskets and possibly head gaskets, very common problem with these, the intake gaskets go bad and the coolant actually burns in the cylinder and of course the cylinder pumps air into the coolant system because of intake gaskets being bad. :-(

Olds silhouette heater blows cold air


as long as the engine temperature is normal, i would suspect a clogged heater core, the dex-cool antifreeze is notorious for building up deposits in cooling system. have heater core flushed first to see if it makes any difference
