Hey mate. PEL500110. Don't know temp. Cheers

Pel500110 is 82 degrees

Yep just found that. And hard bypass Spring. Cheers

With a cooler thermostat it actualy runs cooler around town - 85-87 than on the highway up hills in 5th at 100 - then it creeps up to 90 degrees and then back down to 87 on the flat. I just towed 1.5 tonns yesterday in 33 degree heat and up hills it got to 91.

I am happy with that. I still have plenty of scope. With 2 tonns on the back I suspect on high 30's days up long hills it might creep up to mid to high 90's, but that is very good compared to the previous temps using the stock stat.

The electric fan is not supposed to kick in every time the compressor works cos it's managed on other cryteria:

"Electric cooling fan switching points:

For A/C system:
On = When vehicle speed is 50 mph (80 km/h) or less and ambient temperature is 28*C (82*F) or more
Off = When vehicle speed increases to (62.5 mph (100 km/h) or
ambient temperature decreases to 25*C (77*F)

For engine cooling during normal running:
On = 100*C (212*F)
Off = 94.5*C (202*F)

For engine cooling at ignition off (to counteract heat soak):
On = If, within 10 seconds of ignition off, intake air temperature is 60*C
(140*F) or more and engine coolant temperature is 110*C (230*F) or more
Off = After 10 minutes or if engine coolant temperature decreases to
100*C (212*F)"

A good move is to try to stop the viscous fan with a rolled newspaper when the radiator is hot... if it stops you need a new one cos it's worn and doesn lock well just freewheeling and the engine will not be cooled enough

My clutch fan is working fine. New rad and water pump etc. My engine is very cool but the wiring so that the electric fan cuts in when the compressor cuts in just adds another level of cool...i dont trust the fan on algorithms. Cheers

Ps my fan will still stay on etc if engine very hot (well it should so far no need ) because the activation by the BCU has bot been interfered with
