mad Overheating AU

Hi everyone, I don't know much about cars but was hoping something could help me with my question. My AU was running fine but had to go in for its 120,000km service. Took it to a reputable Ford dealer, who called as usual while servicing it to say that the fan belt was cracking and also 2 of the puller need to be replaced, otherwise if it broke the power steering, aircon and radiator would die. So I got them fixed and proceeded to go out as planned after picking it up. Five km into my trip I put the aircon on 18 degrees, fan at only 3 speed, and the temp gauge just went up and didn't stop. If i tried to accelerate it would just shake! So I pulled over and once the gauge went to H I turned the car off! I managed to get home ok with no air con as it stayed pretty normal. I am just so upset because the gauge has never gone above the o on the normal in the 5 years I've had the car, and now after a service and this new belt thing, it's gone crazy! After the guys explanation that it ties into air con etc, I can only assume that it's something to do with the belt being changed? Thanks.

Re: Overheating AU

Putting the aircon on creates a load on the aircon compressor, instead of free spinning.

Could be a belt tension issue (AU's have auto belt tensioners?.....it looks like a pully with a spring tensioner on it). Belts can still slip without screeching.............and possibly the belt is slipping on the water pump pully too? If so, tighten the belt tension and see how it goes.

Does it work fine with your aircon off?
