P0128 says the engine isn't warming up to proper specs. Start with replacing the thermostat.
Replacing a bad water pump can help to stop a motor from overheating. Hopefully that was the cause of the overheating. If it does not stop the overheating, try replacing the thermostat. Make sure you have the proper mix of antifreeze and water, the radiator filled with it. Check the level of coolant FIRST. Next, the hoses, and third the thermostat. Then, disconnect a hose and see if, by starting the vehicle, if there's water pressure. If not, its water pump time!

All cars need a thermostat for proper operation and longevity.

Replacing a steering column ignition switch on a 2002 Pontiac Grand Prix is not considered a major repair. The task is considered easy but if done wrong could be dangerous. It is best to refer to vehicle manual for the car to ensure proper direction is given.
If you are talking about the engine temp then more than likely your thermostat is stuck open or if you recently changed it the heat range is not proper causing it to open prematurely and not allow the engine to heat up. Change the thermostat and this should take care of the problem. Hope this helps. "G"
The proper tire size for a 1998 Pontiac Transport is P205/70R15. This info is on a sticker placed on the driver's door jam.
If the thermostat is stuck open, the engine will never warm up to proper temperature.
