So once again my car has over heated!

Engine was making a whining noise for a bit than I'm on my way back home and my check gauges light goes on and I see that my fuggin temp is in the red!

I have an SES light but last time I hooked it up to the scanner it was just a p1441 EVAP code.

Any idea plz could use all the help I Can get

Try to do the following in order:
* When engine is cool, open radiator cap, top off the coolant (be sure your coolant
mixture is 50/50 *in* the system and what you pour in).
* Check for water in the oil and vice-versa
* Bleed the cooling system.
* Check for leaks (use a pressure tester)
* Check for collapsed hoses
(let it cool down)
* Have the radiator cap checked or replace it.
* Take thermostat out and check it - put it in a pot and fill with water so it covers
the thermostat - turn on the heat and when the thermo's valve opens, check
what the temp of the water is - compare against the thermo's temp rating.
* Remove the water pump's front inspection cover off and try to turn the
impeller - does it spin freely by hand pressure?

When it comes down to it, there is one of two things that causes an engine to
overheat: (1) Losing coolant (this should be obvious) (2) Cooling system not
circulating (clogged radiator, water pump impeller not turning, clogged engine
passageways or hose(s), and so on).

Since F-bodies are "bottom feeders", a lot of trash gets sucked up in front of the radiator. Make sure it's not something as simple as trash blocking the air flow. Secondly, Dex-Cool can get really "sludgey" if it's not changed regularily. Is the coolant more than 3-4 years old? If so, try giving the cooling system a good flush and refill with a 50/50 Dex-Cool distilled water mix.

thx guys I appreciate the responses. What I've found so far is that the reserve tank was completely empty, I don't know whether it was a leak or if the car completely fried it trying to get itself cool, as last night I literally heard it boiling in the radiator and I saw evidence that there had been some coolant expelled from the reserve cap.

I Got some more coolant and refilled the reserve, started the car and hoped I could see any leaks. I got absolutely nothing. after about 10 min the engine started rapidly increasing in temp and it just sounded really bad when I played with the TB a little bit.

I think the water pump might be going bad, I'd check it myself but I don't have tools. I would go to my auto class but my car couldn't make the drive.

OK, your signature line says '96 T/A...Is this the car we're talking about? If so, it appears that the coolant may be or had been quite low. When you refilled it, did you open the air bleed on the radiatior hose, near the thermostat housing? You might have an air pocket trapped in the cooling system. This will cause it to run hot.

The LT-1 cooling system is "reverse flow" so it's important that A) the overflow reservoir is able to hold coolant, as it's integral to the cooloing system, and B) there are NO air pockets in the system.

It could be a blown head gasket and it's pumping in exhaust gas to the system, heating it up rapidly...

lol no I found out what it was, the radiator is shot, I finally had it started long enough to see all the coolant coming out the bottom...
