engine temperature is hotter if use air conditioning

[markus_74]

hello,

my m40 engine is always getting hot if I use air conditioning and car in stop/not move.

but if the car move the temperature is stay at the middle but if stop the temperature gauge slowly going high pass the middle.

if I'm not using air conditioning the temperature is always stay in the half (car move or stop) without any problem.

I have check thermostat is good, extra fan is good, water pump good, viscous fan is good, air conditioning condenser size is correct.

a few years ago I have make some short route of the water hose in the back of the engine, this hose should be connected to the heater matrix but I disconnect it so the water not enter the heater matrix but I join it to the hose that got water come out from the heater matrix.

I try to solve this problem use 11 blade fan and replaced my 9 blade fan, it help a little but if the car stop longer the temperature still raise

does this make my engine always hot if I use air conditioning?

or any advice?

thank you
