Weird Overheating Issue.
Hey guys My dads truck 97 s10 pickup 4.3 has a weird overheating issue.
The truck gets to 240 degrees. When I open the hood the top of the motor is warm. I could place my hand on top and would not even burn my self. I replaced the thermostat under warranty and it stopped doing it. Today it did it again.
Now I notice the top of the motor is warm and the heat does not work. Possible heater core being plugged? AN other bad thermostat?
Im at a loss. I would flush the heater core but its -12 and the outside water is turned off.
Im at a loss. Its possible the issue is right in front of my face but I dont see it. IM just really cold and tired.

my blazer did the same thing its a 96. flushed it refilled with antifreeze haven't had a problem since... ever since it did get to 240 the rad will only fill up about 3/4ths of the way no matter how many times i fill it it just settles there, but i cant see any leaks.
Flush it hope that fixes it. lol

sadly I wont be able to flush it till it gets warmer. But I do agree with flushing it.. I was on the same track.

same problem on my 96. it would randomly over heat. Flushed it a few times and no problems since.

Dexcool?
When ya flush it make sure ya park it on an incline nose up to refill it.

Sheww my truck hasn't had dexcool in it for 200k when i got it the insides of the rad were so gunked up after 2 flushes, i just went and bought a new one and swapped to good ole green.
Hope the flush fixes it, Good luck!

Drill a 1/8" hole in the thermostat plate.This will allow the air to purge in the system and result in a better regulation of the coolant temp.
