maybe try keeping your overflow at full?

also check to make sure your waterpump is working properly

i keep the overflow full and it does it, waterpump has had less than 20,000k usage.

but thanks.

Maybe a blockage?
Have you power flushed it recently?

Could be a head gasket aswell, or maybe the thermostat is playing up!!

just pray it aint the head gasket!! take it to mitsubishi and get them to hook the computer up to it!!

A seal in my pump went before hitting the 10,00km mark.
Test the water pump by placing the sharp end of a file (aka tang) on it while it's running and place your ear at the other end and listen. It should be a smooth sound.
Also the drive belt for the pump could be buggered or loose.

If you remove the radiator cap, when cold (you may need to drain some water) you will see some small tubes, most likely some of these will be blocked. It happened to me this week. i leaned over and blipped the throttle, and watched the bottom radiator hose squish flat as a pancake. The result of a blocked radiator. If it overheats with normal driving it could be a dodgey thermostat. If it over heats when yer driving down the freeway, most likely radiator.

This was happening to me when I first purchased my new car.

You need to have your radiator flushed, and possibly get a new pump.

That fixed it for me!

Try a good reverse flush of the radiator and the engine - Bars Leaks make a flushing kit that has a fitting for a compressed air line that works really great. Remove the thermostat and the bottom radiator hose, blow through the thermostat housing to do the engine and then via the bottom hose to do the radiator. Be careful removing the hoses if they are stuck, the radiator tanks are plastic and over time get brittle and break at the hose inlets - ask me how I know!

Also check to see if there are any bubbles in the radiator - remove the cap (when cold) and run the engine until the thermostat opens. If you see bubbles in the water this indicates a blown head gasket - or worse, a cracked head or block. Unfortunately the head has to come off to see what the problem is.

Good luck - hopefully a flush will do the job.

If it's your head gasket either you will have an external leak I did and you will find a small patch of water now and again or if it;s internal check your oil cap if there is a white to brown fomish sludge it indicates internal water leakage.
