Question about 2006 Toyota Fortuner 3,0
I recently had the timing belt and water pump replaced and ever since the engine has been overheating when under load. I tow a boat and have to be very watchful of the heat gauge. when driving hard in hot conditions it also occurs. under normal conditions it is ok. The water pump fitted is not an original I don't know if this could be a problem. I had the radiator and head gasket pressure tested, no problem. I am not loosing any water. The worst part is that the aircon shuts down when the motor strains and this is not pleasant. any suggestions would be welcome.
Check between the Air con condensor & radiator for grass etc... (restriction of air flow) if no restriction remove the thermostat & replace. If there is grass do not try to remove with water you will need to remove the radiator & pick it out bit by bit or use soft brush (dustpan brush) & compressed air or soft (not to hot) flame & burn to ash then blow with air. ALWAYS Blow from engine side & remove from other side so you don't force it further in. (This can take hours but is quite a common problem)

i had the same problem, my mate is a Toyota mechanic and started by checking the radiator cap pressure, as if it doesnt have enough pressure it will run out of the expansion tank and leak! So i changed that as it was bad. Then he changed the termostat and things have been good since.

Yes if it hydraulically operated it could be because the pump for the fan is bad. If I am not mistaken the fan is run off of the power steering pump correct. check and make sure the pump is working correctly. I have not seen a hydraulic motor on a car I know they put them on a lot of diesel trucks like humvees and some Chevy diesels but not on a car. Most are usually electrical. I know on humvees with a hydraulic fan they have a fan controller check this and make sure it is working right you can unplug the controller and the fan should stay ingaged and turn faster.

check your antifreeze mix, this is a common problem when your antifreeze mix is too much antifreeze and not enough water. 50/50 mix to 55/45 mix is ideal for most applications. too much antifreeze and not enough water will not transfer heat as well as the proper mixture.
make sure your mixture is 50-55% antifreeze.
