Engine overheating, replaced cracked radiator w/new but problem persists, where is the thermostat located?

should be on right side(drivers side) of plentum. Follow top radiator hose. Area is kind of hard to get to but is a real an easy change. After you change the thermostat then crank engine and bleed air using the bleed screws that are located in middle left of plentum.

1996 acura tl 3.2 overheats and no heat in car\

Have you recently changed your engine coolant? Have you checked your engine coolant? If you just changed the coolant you probably have an air lock in the system and it needs bleed out. To do this i would need to know more info about the vehicle. Another possibility you could have a coolant leak, IE the water pump, radiator hose, heater hose leak. with low coolant the radiator can't do its job and cool the engine. You could also have a broken water pump impeller. No impeller no engine coolant flow threw the engine and heater core.

Bleeding the cooling system

look at your top radiator hose is there a small bleed valve at the top of the thermostat housing when the upper hose attaches to? If so loosen the bleed valve and allow the cooling system to purge the air out of the system you can tell when the air is out of the system when a steady stream of coolant starts to flow out of the bleed valve, if there is no bleed valve take the top radiator hose off of the engine side and allow the cooling system to purge the air out through the top of the engine that way

Where is the bleed valve located on a 1998 pontiac grand prix 2.8 engine? The auto parts store has never heard of a bleed valve.

Was the thermostat changed? I would suggest replacing the thermostat refill the system with new coolant and purge the air out of the system.

A collapsed hose will restrict (or completely block) water flow, causing a overheating condition. Before you do anything else, replace the hose. Some aftermarket hoses are available with a wound steel coil that will prevent a hose from collapsing.

Good time to replace all the hoses and thermostat. If I were you, I'd also flush the cooling system while I was at it. Probably wouldn't be a bad idea to take a look at your serpentine (or "v") belt to.

If your particular vehicle has air bleed ports, be sure to properly bleed all air from the system when refilling with coolant. Usually the bleed ports will at or near the point of attachment of both the upper and lower radiator hoses to the engine block.

Good luck!

Where is the A/C drier (accumulator) located on a 1996 Grand Am 2.4? Thanks

look for two hoses or pipes coming out of the firewall side by side (from inside the car) .. one pipe is small the other is large .. follow the large pipe/hose .. it will attach to the drier (about midway between the firewall and the radiator) .. another hose/pipe will attach to the other side of the drier and that goes to the condenser (in front of and similar to the radiator) ... in order to change the drier you must first bleed off any refrigerant left in the system .. its not legal to do that yourself .. you have to have someone "certified" and they have to recover the gas (they cant bleed it to atmosphere) .. if your system is already at zero pressure then replacing the drier is easy but requires a vacuum pump operating for at least 2 hours (longer in cold weather) before new refrigerant is added .. you can test for leaks by observing if it can hold a vacuum for 15 min or so without dropping .. all refrigerant is added and pressure tested via the valve port mounted on that large pipe (you will see a screw-on plastic cover similar to, but larger than, a tire valve cover .. R134a refill hoses will fit only that port ..

Engine overheating

The best way to flush it would be to take off the bottom radiator hose and pump water through the fill nozzle after all the coolent is out you can then hook the hose back up and replace it with new coolant.
