My 2006 Mitsubishi Nativa Turbo diesel is overheating, replaced

Resolved Question:

My 2006 Mitsubishi Nativa Turbo diesel is overheating, replaced the thermostat, flushed the radiator, replaced the blower motor, pressure test the cooling system no leaks all good, but it still overheats, there is no coolant in the oil or in the automatic transmission, so here we suspect it's not the cylinder head gasket, even though the dealer is taking it off now since they don't know what else to do, can you tell me what else it could be if it's not the cylinder head gasket?

Hi nd welcome to Just Answer!

 

The bubbles are an absolute positive indicator of a bad cylinder head or cylinder head gasket. Have the head checked and the gasket replaced, it is your problem!

Okay I thought that too, but how come there is no coolant in the engine or transmission oil, or oil in the radiator coolant, could you please explain that? Can the bubbles come from anywhere else?

The coolant is going directly into the cylinder and out with the exhaust. I see it happen often that way.

One last few question and I will accept so you get your pay,

Are there heat sensors (3) like a mechanic told me on this car? If so where are they located, because if they are not working or working bad the car will overheat too, is this true?

Where can I get parts for this Mitsubishi Native TD in the US?


Best wishes

If your cooling fans operate then the sensors are operational. Also if the sensor were bad the vehicle would overheat within 20 minutes from a cold start, not after 2.5 hours.

You would have to check with a Mitsu. dealer on the parts, im sure they can get what you need.
