You may have an internal leak,they are common for some of the G.M. engines. Some of the engines are : 2.8L,3.1L,3.4L,3.8L,4.3L,,,, if this is the case you may be able to get a refund,or partial refund from G.M... I would confirm the problem first,then contact a G.M. dealership or 2,to see what they say.
If there is any kind of rattle or rapping in the engine now,,,,, a repair is too late,the damage is done.

2001 Chevy blazer check engine light has been on then last night ,blazer overheated and wouldnt start got towed home started after it cooled off added water to radiator the engine died and will not start...

It sounds to me that your engine shut itself off when it was overheated. If that's the case then you are looking at a major engine repair based on what you are telling us.An engine that gets hot enough to shut itself off does serious damage internally before it dies. You will need to take it to a shop to a complete diagnosis. Hope this helps.

03 mountaineer overheated, underside of hood was wet, hoses good, could it be thermostat housing? and where is it?

maybe it overheated from being low on coolant. Refill and run with hood up and engine gets up to normal operating temp when thermostat opens. Look for leak.

I hate when this happens, had it happen to me also on my Silverado, I bet you didn't change out the sending unit, if that doesn't fix it, you have to remember that just because a thermostadt comes in a box that says it's's a man made object..even the new can be broken.

But, I'd go with the sending unit first.

Thanks for letting , fix ya

Heating Problem

Air would of come out if it overheated, it would of most likely been forced out into the overflow tank. have the water in the radiator tested to see if you have a blown head gasket.
