So I took the rad cap off and sat a very good thermometer in the top of the radiator. Started the car and revved it at 3500rpm until the temp on the after market gauge got to 230F, just at that point when I let off about 2L of water poured out of the radiator. The thermometer in the top of the radiator read 97degrees (its an Celsius one). So we filled the radiator up slowly and again let it warm up just at idle this time. It got to 100degrees and boiled over slowly again, still no fans. So obviously the fans turn on at a higher temperature.
I looked in the full service manual and it says the thermostat should open at 88C, mines a 180F which is 82.2C. And the thermoswitch should kick in between 92 and 100C. So the Fans should of come on, but they didn't. So I'm getting a new thermo switch.
I'm hoping that after I flush the system. Get a new thermoswitch and put coolent in it. It will turn the fans on more often (like actually use them in traffic and at idle) and the heater will work. I'll just have to live with one gauge saying its boiling continually and another barely coming off the bottom..
