You have (at best) blown a head gasket, or (at worst) cracked the block of the engine.
Cars today, being mostly aluminum, break in this manner rather easily.
Repairs will cost you many hundreds or a few thousands of dollars. The car cannot be used until the engine is repaired.
God bless your efforts.

SOURCE: 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

I have had this problem with my 98 aurora and have replaced all the same components. Temp gauge routinely shows 200 on highway (Fine) but in the city in stop and go will get to around 245. I installed a switch to manually turn on the cooling fans by connecting the ground to pin 86 in the relay for the fan(s). Otherwise the fans will not turn on to 245. This fix works but would like to know an actual solution.

SOURCE: coolant leak on 96 olds ciera 3.1

Head gasket. The reason for the cold then hot readings is the cooling system is getting gas bound by exhaust gases. A simple intake leak would just make you loose fluid, but wouldn't cause the other symptoms until the coolant was very low. Which leads me to, is the coolant full? The head gasket most of the time will not leak coolant into the oil, but instead coolant will go into the combustion chamber, and exhaust gasses will go into the coolant. You don't see any white smoke until the leak gets extreme. Then shortly after that the engine hydro locks from too much coolant in the combustion chamber. There is a tester that will test your coolant for CO gas. That is the proof of a head gasket leak.

SOURCE: po410 secondary air injection system malfunction

Two of the more common problems with Auroras.
P0442 - There is a small solenoid (about $30.00) mounted near the L.R. wheel that will fix this.
P0410 - Usually due to leaking Air Injection Valves. These are about 2" square, one near the passenger side firewall, the other near the drivers side radiator. They cost about $200.00/ea. most people just leave it go as it does not effect performance.

Do the cooling fans work ? Could be the step motor that controls the temp. gauge . How are you determining that the vehicle is overheating ? Gauge on insturment cluster ? GM had bad step motors inside thier insturment cluster's . 2003 to 2006 ! Your best bet , take it to GM dealer .

My heater is not working and is blowing cold air and it also is overheating


your coolant lavel is low or you have a head gasket problem/ leak. If the truck has a 4 cylinder 2.2 litre engine it is probally the head gasket.

If you crank or start he engine and the antifreeze blows out for the radiator it is due to blown head gasket pushing cyl. compression into the cooling system. The head will have to come off.

1999 Pontiac Grand Am Overheating


It is probably the problem. To make shure that need to change the gaskets, one of the symptoms use to be thet the temp rises when you are running at speed 50+ average, where is supposed that the car gets a lot of air due by the speed and nobody thinks that will be overheated.
