pajero gen 1 turbo diesel 4d56.
the problem is that when i turn on the a/c, after 20-30 min the temp needle guage goes at 50% in the middle & that makes me start to worry, and afterwards when the car stops after long drive, most of the water from radiator is evaporated & i have to refill it & top it up, the radiator coolant reservoir bottle is working fine, and everything ok with no-leaks in radiator & condensor fan also working.
This problem only occurs when turning A/C on.
But also, there is no coolant in the radiator, im only using water.
is it necessary to put in coolant? if yes , then which company coolant & how much?
Or do i have A/C Compressor problem ?
help is needed asap.
Thnx for ur time.
