Remove the thermostat, check in pan of water for opening temperature, replace IF it does not respond to various water temperatures...follow the radiator hose from the top to the top of the block...the little cast iron BULB contains the Thermostat, drain radiator first...drain plug found on bottom of radiator, take off radiator cap to equal the pressure which will enable it to drain...if cloudy/dirty, replace with new solution/water..

I over heated,the serpentine belt snapped. Opened the hood to find steam rapidly coming out of both the antifreeze and out of the engine right by the head gasket. It wasn't smoke not blue or black jus

Perform a compression test on your cylinders. One unfortunate result of overheating is the blown head gasket. Without compression your motor will not run. Tester are not super expensive or some stores will lend tools.

No pressure in the cooling system, losing coolant then overheats.

you have a head gasket that is failing. You can confirm this by having the coolant "sniffed" with a four gas analyzer (normally used for emissions testing). If your coolant has hydrocarbons in it than its coming from the head gaskets. They are pretty common for this engine.

I have a 200 saturn and every once in a while it won't turn over...battery fine and no engine light

If it is an automatic shift you should have a neutral safety switch between the key switch and the starter. I would check that and for power at the starter when it fails to crank.
If it is a manual shift there is a switch on the clutch pedal or linkage.
It may be tough to find until you can duplicate the problem on demand.
Could also be a dead spot in the starter or solenoid.

Will not blow heater hot when first started

I don't understand no cars have heat when first started. Lets try this engine cold take cap off radiator put in a thermometer like a meat thermometer it will read the temp of the water the antifreeze should be right to the top. Start the car and let it run when the upper radiator hose gets hot all of a sudden that is when your thermostat is starting to open it will read 180 to 195 on the thermometer it will fully open at 200 to 215 and the electric fan should be off till it is above 200. If the radiator hose feels like water is going through it right after it is started and the engine slowly warms up to about 100 to 120 and won't go above you have a bad thermostat replace it. If this helps please rate it thanks. If you have any questions just ask I will be watching the post

I have a 65 mustang 200 engine. After changing

Make sure you were given the right plugs for the car (correct heat range) also check the choke plate after the car warms up to ensure the choke plate is all the way open.
