Drain some of the coolant until you are sure it will not spill over when you remove the hose.
Remove the hose from the radiator .(Top) Hose. follow the hose to the thermostat housing. Remove the hose by removing the clamps.the thermostat is located in the housing. remove the bolts holding the thermostat housing. remove the housing. be careful to notice the position of the thermostat. Make sure you get the proper degree thermostat . Ask the vendor. give as much info as possible. mainly the size of the engine. remove the thermostat. You will get a new gasket with your new thermostat. Clean off the sufaces of the thermostat housing before installing the gasket.use a little grease to hold the gasket in place. and reinstall the new thermostat. replace housing and hose and refill with antifreeze/coolant. i hope this works for you and you vote for my answer.

Should be in a housing just at the motor end of the upper radiator hose. Trace the upper hose down under the alternator.
Pull the hose off (be sure you have a way to catch the coolant first!) Then you unbolt the thermostat bolts and pull out the thermostat. REMEMBER which way it goes---the part with the "nose" points toward the radiator. Then clean both surfaces of the housing really good, and put on a new thermostat gasket. You can seal it with some light white grease, but just enough to make the gasket stick. Don't use goopy silicone sealant! Tighten the bolts but don't go crazy. Just enough to strain the muscles in your arm using a 3/8 drive wrench. Do NOT put your back into it. NICE and SNUG. Now you have to fill up the plastic reservoir tank. Then you run the engine for for just 30 seconds or so, then shut it off. Now you have to find the BLEED SCREWS and open them up so as to let air out of the cooling system. Then close the air bleeds. Repeat this filling up and running the engine briefly until coolant comes out of the air bleeds. Then top off the reservoir tank.
I think one air bleed is by the pipe where you put in the oil. Once you find it, look for another one like it. Sorry I don't have a manual for your car.

You need to raise the vehicle and start it. Remove the plug near where the passenger side driveshaft comes out. The head of the plug is 7/16. Trans fluid will stream out of the hole when the engine is running when the transmission is full, If fluid doesn't run out, fill the trans until fluid runs out. The fill cap is red and it is on top under and around the air cleaner box. If you need more help let me know.

Pontiac has bad habit of moving them around on us.
Example: on the 2000 Sunfire it is at the outlet of the condenser up near the front of the car. On the 1998 it is on the high pressure line right as it enters the firewall.
Therefore I am comfortable in saying that you will find it in the outlet of the condenser up near the front of the car.I recommend that if you are doing this repair yourself, ensure you replace the o-ring on the line itself with a new one.
Thank you for your question and good luck.

Your thermostat is located under the thermostat housing, which is what the upper radiator hose clamps to on the top of your engine. Basically, you need to start with a cold engine, drain your radiator, then unclamp the upper radiator hose from the engine. Remove the bolts from the thermostat housing, and gently tap on it to remove it. clean up the mounting surfaces on both the engine and the housing, and install a new thermostat, and new gasket. tighten to proper torque, reconnect the radiator hose, then refill up the radiator and cooling system.

Testimonial: "Thank you, very helpful"
Lock handbrake, loosen lug nuts, jack it up and set on axle stands and remove front wheels.
Unbolt the brake caliper, tie it up to the suspension arm with a zip tie etc. Don't let it hang loose on the brake lines. Unbolt the brake rotor from the hub. You might need a friend to stand on the brakes to keep the rotor from spinning.
Once the brake rotor is off, undo the center hub nut (usually a large bolt 22mm or bigger). Keep these in order when you remove them, the castle nut is next (looks like a little castle turret), washers, a lock nut and then finally the bearings are next. Clean out the aperture with a clean cloth.
Regrease the bearings and the inside of the hub. Refit the parts in the right order. Be gentle with the lock nut, it may take a few goes to get this right as it can be too loose or too tight, making the rotor (when it's back on) feel stiff to turn.
Refit the rotor, brake caliper (make sure the brake line is not crimped) and do the same for the other side if it is necessary. Refit wheels and take her for a spin.
Vote for me if this helps you. Thanks
