hmm, well, besided the radiator leaking and having bad head gasket's i'm starting to think there is another problem. Yesterday while i was driving my car, it got up to about 240 and never started to blow hot air, it was cold, hmm, i just thought, how about the thermostat? or possibly the heater core.

If it overheats in this friggin cold weather you have a problem. My aurora ALWAYS was at or above 250 in the summer. I always wondered... when it was 85 degeres out it would get up and over 110 degrees within the first minute of starting it. After i replaced my rad, it was fine. Also the water pump was F'ed so that had to be replaced, ands that problaby why it was ding that. They said it looked so salty and gumed up like the coolant has never been changed before i thought FOCK.

well, i replaced my water pump only about 2 months ago so that should be fine, i just hope it's not that damn heater core, that's a pain to get to from what i hear

Could it be an air lock in the heater pipes wot with all that coolent leaking?

A bad thermostat might be causing the overheating. The HVAC controls could be at fault for the no heat problem. Another thing to look at in this area would be a blocked heater core. _________________ GM!!! BRING BACK OLDS!!!  |

I hate to be the bearer of bad news. Overheating + heat does not work = blown a headgasket is starting to manifest  Check for coolant in your oil or spots in your coolant reservoir to confirm. |

if coolant was in your motor oil could that sieze up your motor? i think antifreeze dilutes the oil and becomes primary takign over the oil and it is just like water, which we all know is NOT a very good lubricant lmao

It's an easy way to spin a bearing. Also, if your heater core were bad you'd have coolant leaking into your car on the passenger side. A bad heater core won't cause no heat unless it's plugged up but what is the chance it's plugged. I'd check to make sure your thermostat is opening. Sounds like maybe it's not. Also could be your climate controls. But if there were something wrong with the climate control itself wouldn't the display flash? I know it did on my Riv, and all of our Bonnevilles when there was a problem with the climate control system. |

Somebody sure jumped on the head gasket wagon way too soon. Blown head gaskets either leak coolant to the ground, puddles under the car, leak to the cylinders, white sweet exhaust, or rarely into the crankcase alittle coolant kills bearings fast. the heater core was probably the no heat culprit. The mechanic said the coolant looked salty and gummed up. doesn't take much to plug a heater core. 240 to 250 is where my 95 runs all the time. Hot or cold it doesn't matter.

Yes but isnt 250 degrees Farenheight bad for the motor? it doesnt do that anymore btw. in the summer when they inspected my water pump, they said THAT looked salty and gummed up due to the coolant probably was never changed, just topped off and it was restricting the other passage where it transfers.
I cant see why anyone wouldnt change their coolant once every 2 years. It doesnt cost too much.

Well, in recent news on my car, the mechanics don't think that it has a bad headgasket, they're actually not sure what it is, but has no tell-tail signs of a bad head gasket, the plugs are burning perfect and there is no antifreeze in the exhaust. So the thermostat, radiator, and coilpacks are the culprit as of now on my car.

Thats good news - you are extremly lucky. Has it been me, it would be not headgaskets but cracked heads for sure  Have them take a look at the waterpump as well. |

even though i replaced the waterpump less than 2 months ago?

You never know, it a defective unit could be the cause of your problems.

Supastealth, this just came to me. Check for coolant pressure once the engine warms up a bit. Wear some gloves (you don't want to burn yourself) and give the top radiator hose a good squish. You should feel coolant circulating, especially if the fan turns on. No coolant there would indicate a stuck closed thermostat or a bad pump.

yeah, i did that when i was trying to get the air bubbles out after i flushed the coolent. there was pretty much nothin' there.
