Gettin a bit hot... viscous fan?

<< < (2/4) > >>

ben_haynes:
yes when the engine gets warm it should lock

way to tell is get the engine warm and using a stick try stopping the fan if it stops then it is Knackered (just dont Use ur hand just incase it is not knackered :shock: :->)

Ja1983:
well, it was warm when i stopped (tad too warm....) and it moved independantly of the engine.....


new viscous unit methinks :doh:

Range Rover Blues:
Been there, done all that.  Even though I thought my rad was ok I ended up swapping it, and put a new vicous on.  The newone is even looser when cold, but locks up bvetter when hot.  That and the new rad mean I have no more heating problems.

Electric fans are over-rated.  You'll never save enough fuel to pay for them and they can't shift half as much air as the viscous.  kenlowe advised me not to fit electrics :shock:

Ja1983:
if electric fans worked better, surely they would be standard fit... i recall reading that the viscous unit was favoured due to the likely workload and temperature extremes its likely to encounter..

got a nice clean intercooler to fit aswell, and its booked in tomorrow for a replacement viscous jobby!

fingers crossed... working through the to do list faster than its growing at the mo! :lol:

Range Rover Blues:
I rang Kenlowe to buy a apir of fans for my LSE as it was overheating.  They admitted that a pair of their biggest HD fans could not move more than about 60% of the air that the viscous can so with the size of my caravn they would not guarantee their fans would be up to the job and suggested I replace the viscous hub instead.  Nice of them to be honest ;)

In the end I got a good deal on a new rad and viscous hub, £200 for both.  Job done, car happy :)
