fans spinning constantly
recently purchased 95 x300 4.0.It's great.So far everything i ok.But..
both radiator fans start spinning as soon as i turn the ignition ON.Is this ok or should I chek the relays and sensors? The car heats up normaly and the temp is ok.Thank you

RE: fans spinning constantly
Hello!the fans spin wnen ignition is on and a\c is off.
Iwas told it is normal and they start spinning at low speed (in series), but none of my previous cars was designed this way, and that is why i am suspicious.
thank you for your instant reply. Sorry for my poor english!

RE: fans spinning constantly
I had the same issue with my Porsche a few years back. Since the Porsches' radiator fans work independently of the ignition switch, I discovered the problem through a dead battery. Jags' fans work through the ignition switch so your fans won't run with the key off. My Porsche problem was a simple thermostat that screwed into the radiator. Replaced the thermostat, problem solved. Of course I'm speaking of the wired or electric switch, not the thermostat that regulates the coolant into the engine.
I would say it's either that thermostat switch, which typically fails in the on position (thank goodness), or the fan relay that has failed in the closed position.
