can i remove my viscou fan as i am sick of propeller action in water..i am told the 200 tdi lump should stay cool?

Andy41:
yes if in doubt put it back in summer thats what i do  ;)

squaddie_fox:
as said above diesals are overly cooled rip it off or if u get worried chuck a eletric fan in an wire up a switch so u can turn it on or off when u want

Range Rover Blues:
Not so much that diesels are overcooled but that at part load they are far more efficient so produce less heat.  I've just been out in the wife's and TBH in traffic the engine won't stay warm enough with the heater on :-.

Sit on the motorway and it gets plenty warm, stick a trailer on the back in the summer and start worrying about the temperature.

By this age most viscous fans aren't working 100% anyway, they are too stiff at rest and too slippy when needed.  Add that to a silted rad and you might have problems.

But TBH in this weather take it off, if you leave it in the boot you can always refit it, you don't need any tools to put it back on just patience, line up the thread and spin it up hand tight.

IIRC it might be a RH thread on the 300TDi, usually Viscous fans are LH thread but you can work it out by looking at the angle of the blades.

One thing though, if you bin the fan you have less cooling on the intercooler because the viscous fan keeps air going through it all the time.  I'd thought about putting a small fan on just for the intercooler (in ours it would be in the space the original intercooler fitted) and have it run just when the engine is at full throttle, when you need the intercooler most.

But you know what thought did........

im lucky cuz mines got air con on it so if temp guage does look like its goin up i just knock the air con fans on an they normally sort it out
