I have a 11/99 Malibu. It started to overheat while driving on the highway. I replaced the thermostat and water pump. Tried to flush out the system as best as possible. Blew out the radiator fins. Confirmed that the cooling fans came on at around 220-230 degrees and that they were spinning at a good clip. Replaced the radiator cap and topped off the coolant. Checked for coolant in the crank case and looked for white smoke from the exhaust. I drove the car for 1 hour on back roads at about 40 MPH. No signs of overheating. The next morning the car was driven 5 miles to the highway. Once at highway speed (55 MPH) it overheated again. The coolant is blowing out of the res. Overflow tube. Any chance there is some bleeding issue or maby the radiator is partially plugged and can't cool the water while the engine is spinning at faster RPM's while on the highway?

When I bleed the system I first get air from the bleeder then water. Is there a special proceedure to follow to bleed?

I also noticed that the interior heat blows cold when the temp gauge spikes real high then it blows hot when the needle comes back down!

Do you have a pic or diagram where the bleeder screw is at. I see a screw on the housing but it doesn't look like a bleeder screw, but it has a blue paint on top of it.

Not sure on the year of the car cause I am borrowing it but it is in the right range.
The car when you run it will go to maximum heat (like overheating) but then will begin to resume normal operating temperature from there on out.
Subsequently, this is happening in conjunction with the heater going out. Since it was -10 here this morning i'd like to try and get this straightened out ASAP. The vehicle is also tossing some fluid on the ground whi believe to be coolant.
Thanks in advance!

My Car is over heating. Currently the car can sit in one spot for hours and not over heat, when you start to drive the temp will go up and during this time the heat does not work, as I am driving some times the heat comes on and the temp goes down. I have changed the thermostat already. Events that led up to this were. I went into get my oil changed, after the oil change I drove the car for about a hour, it over heated.I then opened the hood to find a squirt bottle stuck in the left side fan. I then removed it from the fan and contacted the shop that changed my oil and brought the car up there. When I got there they promptly said that the bottle could not have caused any damg that would make the car over heat once the bottle had been removed. Also the mechanic switched 2 relays to the fans saying something about polarity. My question is could the bottle have caused the damg causing the car to now over heat, if so what damg is likely the cause. So far I am into the shop for a oil change and 120 for the thermostat, which is what they said was the cause.

My car overheating only when driving. I have replaced the reservoir, water pump, thermostat, radiator hoses, and it still overheating. I can have it setting in my driveway for hours running and it will be fine but if I start it and go about a mile from my home it will overheat to the point were it is in the red. Help please.

the problem is that my fans arent turning on to cool the rad fluid down so its constantl boiling over when driving through town, on the highway its fine. I just replaced the water pump and the temp sensor and the problem still occurs is there anything else that I can try

Sometimes the fans come on with the ac the work in both low mode and high blower mode if I unplug the temp sender
