Overheating problems usually warrant some troubleshooting. First, check your antifreeze level. If it's low, replace it, run it for a couple of minutes with your heater on, then recheck it. Next, your thermostat could be stuck. For about 30 minutes worth of work, and about $10 of parts, you can do this replacement yourself. This will usually give you the symptoms of having one coolant hose being hot and the other cool, if it's the thermostat that's stuck closed. The next place to look is the water pump. There aren't too many reliable ways of testing one of these at home, so it's pretty much a replace and pray, because if it isn't, then it's something more serious like a blown head gasket or a cracked head. These last two can disclose their presence by evidence of oil or antifreeze leakage, or white smoke when you first start up your vehicle in the morning, but will not always do this.
I have an 2005 nissan sentra and the heat will blow cold then hot. then my car overheats,and i checked the reserve tank was full 2 the brim like all the fluid ran in there from the radiator .do u no why?
I have just had a simmilar problem with overheating. I have replaced the water pump and temostat but it is still overheating. I am now replacing the head gasket and all the other gaskets around it, I am also replacing the temperature sensor. I will come back and give you the feedback if it works.
2002 oldsmobile silhouette, rear passenger will not turn over to air conditioning. even though front is on air conditioning rear still blows out hot air. You can not hear flap change to air conditioning: where is this flap located ?

The first thing i would check is all 4 abs sensors at the wheels.You can do this with a volt meter set on ac voltage and spin the wheel if it generates voltage at all on the meter its good.

This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck
