| Electric cooling fans
I wondered if anyone knows if the dual electric cooling fans infront of the rad on a G500 should activate at the same time or do they trigger one at a time on occassion, and how loud should they be? Mine seem to be quite loud and only have been able to witness one turning at any given time.
Something to add to the waranty list possibly
cheers

They are noisy, but mine always work together. They are thermostatically controlled. |

They should always work together. If only one is turning it is defective.
One of mine didn't work when I got the truck. It appeared to be a manufacturing flaw, some sort of chemical had gotten been spashed on the copper braided lead for one of the brushes. With a new braid it was off and running. The motors are not set up for easy repair, however a dremel will cut a nice window into the body to allow inspection and repair. |

I noticed the same thing with mine - that only one was working, in this case the left hand one (when looking at the front of the car). I was in the process of replacing my a/c condensor, which involves removing the electric fans. I couldn't get into the fan body to identify a fault but, instead, sprayed in a fair bit of WD40 into both electric motors. Both fans now work at the same time and I haven't had a reoccurrence.

Mine seem to be dependant on the A/C. Is high coolant temp also meant to activate them and if so how do you go about checking this circuit? |

They are dependent of the a/c and temperature and controlled by thermostatically. So - they won't should work together. First the left one switches on and if this is not enough - the right one will switch. |

How does it work on 280GE?There are two fans, one in front and one behind the radiator? I have not noticed the front one to turn on. What does it do and when? |

Caveat: There may be wiring differences.
On most, if not all, later model G's the two fans are wired together. This pair of fans can be turned on by either a temperature switch (120C?) in the cooling system or a pressure/temperature switch in the AC system. |
