Check the heater hose in the rear between the firewall and the block. Turn the car on and grab a flashlight and give it some throttle from the engine bay while looking to see if you see coolant spray out under load.Be sure to test your radiator fan. You can start up your car car and let it idle until the engine reaches normal operating temperature, and that should cause your fan to come on. If your fan does not come on even as it starts to overheat, then you should replace your cooling fan. It is possible your radiator is clogged and the water is not being cooled properly. If you do replace your radiator, be sure you replace your upper and lower radiator hoses as well to be safe. If not even that helps, the only other thing I can think of would be your water pump. If you've never replaced that before, it would be a good idea to replace it. There really isn't that much to your cooling system, and it sounds like you've already replaced some of the most common causes for this problem. You can even try to use a coolant mix with more water rather than anti-freeze; like 70% water and 30% anti-freeze. Look at your thermostat, could be stuck closed, they go out. Look to your ac unit, look at the smoke coming out from exhaust tail pipe especially at morning start up, what color emissions smoke , blueish or white is blown head gasket.

97 mitsubishi eclipse spyder 5 speed overheating

Sounds like you lost your drive belt on the vehicle. Check to see if you still have a drive belt. Without a drive/serpentine belt you will get exactly what you have described. I'm just guessing but this is the first thing I would check. Hope it's something that simple for you and that you didn't get your engine too hot and I was able to help.

1995 Mitsubishi Eclipse stalls out when driving or shuts down when at stop?

If it is overheating replace the thermostat.

Have you tested the vacuum pressure to make sure there is no leak?

I would also check for loose, or broken connectors/connections. Make sure the battery cables are securely tightened and not moving around or corroded.
