Have a 97 grand prix my car is running about 210 in the thermstat (that is in traffic but on the interstate it runs about 160), but it smell as if it is overheating, it leaks a lot of water when you turn it off, the water/antifreeze level is not low and i had it checked out they said it was the ac leaking (there was a lot of water leaking) any suggestions

I suspect these problems are unrelated.

Braking shake is usually caused by warped rotors or drums. A brake shop can machine or replace these.

A burning smell is most commonly caused when a drip from an oil leak hits the hot exhaust system. It does not need much to smell terrible. You will see brown or black stains on the exhaust somewhere.

indicates a head gasket problem
at idle the gasket is sealing but under load is allowing compression into water jacket
do a compression test
check cat converter for failure blocking exhaust
run fault codes to check for mixture control problems

If you did not disconnect the battery and drain the voltage from the ECM, it could be using old settings when the problem existed.
When a problem occurs, the computer tries to correct it or find new settings to work around the problem. When you fix a problem you have to clear the codes and sometimes erase the memory from the computer to allow it to start back at the factory settings.
When you disconnect something and the check engine light comes on, the computer goes into limp mode and uses values for the sensors preset by the factory. The car will almost always run rich to ensure the driver can get back to a place for repairs.

Sounds like the fans (which are designed to simulate the wind when u are not moving) are not cutting on. While car is running in park and with the AC on, look under the hood to see if the fan is running? If you have 2 fans, one will run when the AC is on, the other when the car reaches a certain temperature. Post your findings for additional instructions.

Likely you have oil seeping on the exhaust manifold(s) from a valve cover gasket(s). Go under the car and take a look.

You may have a bad fuel injector or in need of a tune up badly. The early fuel injection (throttle body) had a single fuel injector that would clog and not spray fuel in a mist but would dump fuel. Does it run rough at idle? That is a good indicator. Some are rebuildable but I would suggest replacement. If you have not had a tune up in a while that should be done too.

97 Grand Prix has an L36 Engine if N/A, L67 if Supercharged

Transmission is a 4T65E (-HD if supercharged)

Buick Regals, and Monte Carlo's share the powertrain and driveline along with a handful of other vehicles.

yep i seen it in happen .i was at a gas station a guy drove car to the gas station on empty.he fill his tank up .could not get it to crank .some cars you have to restart fuel pump when run out of gas. like chrysler.you use a scanner. but chervrolet you run low over heat damage the pump.it has to stay submerge gas to keep it cool. check fuel pump pressure.it should be 41 - 47 psi.

Go the Cheaper Route First and Go back to the Parts store and ask for a Cooler Thermostat. Try that and let me know what you have got.
