There are a number of possible causes for engine overheating. I suggest you take it to a mechanic that could provide a free diagnostic to get a better idea of what is happening.my 2006 equinox is over heating an one got the fix on it or should i junk it now
I will share this experience with overheating on our Torrent: When we took ours in to have the blend door replaced (under warranty) we discovered that a previous owner had damaged part of the air conditioning system in their own attempt to fix the problem. We paid the difference and had GM replace those parts as well. Part of this repair involved removing the dash, heater core, evaporator, etc. Shortly after picking up the car it began overheating. We took it back to the dealership since we had not had this problem before, and they said it had nothing to do with the repair they did; they said it was the cooling fans not working properly. Their quote to replace them was very expensive so I bought the part for $100 and did it myself. It was not an easy job, but now it has new fans. However, the problem continued. It was at this point that I noticed some coolant leaking under the car.
I took it to Pep Boys and they put a pressure meter on the system and discovered that the cooling system was loosing pressure. It was easy to see that the coolant was spewing from the point where the coolant hose connects to the heater core at the fire wall. I am not 100% sure that the dealership reused the old clamp instead of putting a new one on, which caused the car to drain its coolant and overheat. One 25 cent clamp later the issue was fixed and the car runs beautifully.
SO, look into the cooling fans (especially the connector, which is likely black and burnt and just needs to be cleaned) as well as monitor your coolant levels and have it checked.
