Question about 2003 Mitsubishi Outlander
I bought a mitsubishi shogun 3.2 diesel at auction, and it is losing coolant.
my exhaust is not white, so i don't think its going into the combustion chamber.
my oil is not creamy, so its not getting in there.
there are no visible leaks.
on the motorway, after 20 min, it runs hot - 3/4 indication on coolant temp gauge. Then it suddenly drops, as if the thermostat has opened. When I get home the reservoir is empty, and after the rad cools, i open it and need to add a litre and a half of water.
Sounds identical to a problem I had on my motor this year. The EGR or exaust gas recirculation cooler to give it, its full name had failed. Basically a little radiator sits on top of the exaust manifold and admits some exaust gas back into the engine. Its water cooled and they do split loosing coolant internally into the exaust. Good news is its an easy job to replace not so good news is they cost £220. To check yours you need to remove it and look into the pipe that feeds the inlet manifold, any sign of water there and its goosed. Hope this helps, Neil

Have a pressure test done on your hoses, you may have a small hole that allows the coolant to escape while the system is under higher pressure
but is not present at idle
