The big cooling fan makes a lot of noise and saps power and I'm wondering how necessary it is given that there appears to be an electrical fan fitted already. Does anyone have experience of removing it please? Regards Tony.
An electrical fan is not part of the standard cooling package. It would come with the air conditioning(a/c) option if you have that fitted.
I'm not sure if the a/c fan can operate to cool the engine cooling system if a/c is not operating. Perhaps someone knows. If the electric fan has been a user modification (i.e. not part of an a/c package) you've got a better chance of having some control over when it runs.
Whether you could sensibly remove the engine driven fan much depends on how you use the vehicle. If you only do very short journeys you could even run with the cooling system dry - but I don't imagine that's the case here!
If there's the chance of getting stuck in traffic in warm weather, you do slow speed high output running or towing removing the main fan is probably not a good idea. A working temperature gauge would be essential. Is this an automatic? The fan also helps cool the gearbox oil
- don't remove it.
Unlike the old series L/R it's not a quick job to replace the fan should you need to do so. It's probably inconvenient enough to discourage you from doing so between winter/summer and vice versa.
You have a viscous-coupled fan which doesn't eat as much power as you may imagine - it should largely freewheel unless needed. Is your existing fan coupling operating correctly? Normally they run noisily for about 30 seconds-ish after engine start and begin to quieten (freewheel cutting in) thereafter until needed to operate.
Thanks for that, my car is a maunual and it does have a viscous coupled fan, I didn't realise that it had the capability to self- regulate, does that mean it slips less when it's hot so moving more air? I'm just aware how much air is moved around when I rev it.
Yes. It reacts to the temperature of the air coming out of the rear of the radiator and slips less as the air temperature rises.
The viscous control has been known to fail but a simple observation of what happens from start up as suggested above will give you some idea as to how healthy it is.
