Question about 2001 Chevrolet Monte Carlo
My 01 monte carlo ls 3.4 is overheating within the first couple of miles driving it. I have replaced within the last 6 weeks upper and lower radiator hoses, thermostat (a 180 to help it run cooler)cooling fans (and hardwired them to a switch, i turn them on whenever the engine is on) water pump, and radiator cap. I took it to a radiator shop yesterday and they said my intake gasket was leaking. okay cool, i replaced it last night, used rtv on the gasket, let sit for 12 hours before starting just to make sure. i go to get some gas this morning and within 3 miles it overheated again. when im on the highway (70mph) for long distance it runs cool, its when i do the stop and go it starts to overheat, but 99% of my driving is stop and go, not on the highway. i live in south florida so nothing is frozen or needs to thaw. i dont have any coolant in my oil, or smoke in my exhaust so that leads me to believe that my head gasket and seals are good. someone please help im running out of ideas and money.
You have to bleed the air out of the system. There are 1 maybe 2 bleeders on the front of the engine on the cooling system bypass pipe one near the upper hose the the othe on the drivers side of the pipe. They are brass with a small bleeder valve in the middle. Get the car up to temperature and take your time to allow all the air out. Refill cooling system after it cools. Hope you didn't do any damage running it hot.
