Hi ya. We have a hilux surf 1988, turbo. We travel with the air-con on and go up a hill and we loose power and temp gauge goes into the red, only does this when air-con is on. Temp goes back down when you go along the flat. Only started doing this 1yr ago.
We have had the following done: radiator, hoses,thermostat,temp sensor,pressure test-hot and cold,added an extra fan on the front.
Have had it to 2 diesel blokes without success. Use to get 400 to 450 ks now only get 350 ks.
think thats about it.
thanks
debbie
