I am all out of ideas and need some outside the box thinking.
I have a 120 with the 1KZ turbo diesel. When under load (towing uphill) the temperature steadily rises to the point of shutting down the ac compressor and on the odd occasion triggering the AT HOT lamp. I had this happen yesterday driving up the Toowoomba range without towing and just my family in the car.
I have been chasing this issue for some time and have done the following:
Added a separate transmission cooler
Added a separate oil cooler
Replaced the viscous fan hub
Bypassed the thermostat
Added a thermofan (manually operated)
Any other suggestions?
