Question about Mitsubishi Diamante

3 Answers

My 2001 Mitsubishi Diamante overheats when air conditioner is on for extended periods. If I turn off air for 5 miles and then turn it on again it is ok for another 20 miles.

    It appears that i have only one fan and it runs when my air conditioner is on.

    If I do not engage my air conditioner it does not overheat. And.. if I wait for 2 miles before engaging my air conditioner it will not overheat for up to 20 miles. If I start the car with the air on, it will sometimes start to overheat after just a couple of miles -- but it never overheats with the air off, and will return to normal as soon as the air is turned off.

Sounds like you may have a restricted radiator. the condensor for a/c is in front of the radiator.this disipates heat and will put an extra strain on the cooling system.if your radiator is clogged the additional strain would be enough to cause it to over heat. pull the top radiator mounta loose and gently pusha radiator back and see if you have a bunch of debris stuck between rad and condensor

Hi,

Often usual causes for overheating would be:

  • stuck/defective thermostat (most likely);
  • radiator fan failing to engage ( could be caused by relay, thermal switch, silica oil clutch) (and very likely);
  • clogged radiator;
  • too soft upper & lower radiator hoses.
In some other instances, overheating could be caused by:
  • engine out of tune, overloaded with A/C on;
  • other factors with the engine system.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

The cooling fan probably isn't coming on when the a/c is. On some cars there are two fans one for the a/c condensor and one for the radiator. If there is only one the fan should be constant with the a/c engaged.

The air conditioner for my 2001 volvo v70 turbo will shut down periodically while running in hot weather or when running while the vehicle is stopped (traffic) for an extended period. Shutting the AC off,...


There may be a restriction in the plumbing of the air conditioning system that is making the high side pressure too high, thus shutting off the a/c for safety reasons.

Or, the refrigerant pressure on the low side is too low, caused by not enough r134a refrigerant in the system.

I have a 2001 diamante and it will not shift in to any gears.


Yes...

You are absolutely correct.

The Mitsubishi Diamante has the advanced electronic transmission, which MUST only use "special" Mitsubishi transmission fluid.

Contrary to belief, having excess fluid in your transmission can cause havoc, just as not enough fluid can.

So, it's imperative that the fluid level be checked while engine is warm, in park at idel speed.

As the condition of the fluid is critical, you should change the fluid every 30,000 miles/50,000kms, to avoid costly repairs.

Cheers,

I want to repair the heating of a Mitsubishi Diamante - 1999


The heater coil is malfunctioning and if you dont have it fixed soon it will begin to leak on your ECU and cause the car to go into failsafe mode which essentially means it will be stuck in 3rd gear whilst flashing neutral, meaning the car will lag terribly until you reach 60km/h. The car should not be driven for an extende period whilst in failsafe mode. You have a small problem at the moment but if you dont see to it quickly it will be very costly.
