Weird overheating problem
Car is overheating faster when the AC is turned on.
I did a radiator pressure test and there was no significant
drop in pressure over several hours.
There are no leaks. No visible exhaust fumes. Oil is clean
no water is leaking into the oil. Small amount of coolant
can be seen under the plastic reservoid but not enough to
explain the great loss of coolant.
I have been refilling the reservoir tank with 1 to 2 liters of
water for every 100 kilometer driven while driving it
Pressure stays when the radiator cover is on.
