Did you change the fluid? There is an "air bleed" near the water pump that has to be pulled to allow the coolant system in that car to fill correctly.

If you did nothing, and this just started, you may have a head gasket leak. On that car it is possible for the gasket to fail at the cylinder wall, and there will be no indication of oil in the coolant, or, coolant in the oil.

If you cannot figure this out quickly, get profesional help. I didn't and my 93 G20 is now rusting in a junk yard in florida. Started with overheating, blew the head gasket and then warped the head. I fooled myself into thinking everything was fine after replacing the radiator and the water pump, when the real problem is that gasket failing. It actually isn't a gasket, just RTV and it fails around 120-150K. Good luck.

If you have coolant, and are retaining that coolant, yet your engine is still running hot then the coolant is not being circulated.

That means either 1.) The thermostat is not opening (it opens at a pre-set temp to allow coolant to circulate through the engine), or 2.) The thermostat is opening, but the water pump is not pumping the coolant through the engine.

I have seen it where a thermostat has "caged" from old age, where it will no longer open and close.

I'd suggest replacing the thermostat first. If that doesn't fix your problem, then your water pump is bad.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
