COOLING ADVICE ON A V8 PLEASE.

[shrekster]

Hi all..

I have just purchaced a 1984 110 v8 crew cab, it needs a bit of work to get it sorted. i have not run it on the road yet as it has no tax or test. It currentley has a twin kenlow fan set up fitted, What i want to know is ..  Are these fans better than the original viscus fan set up or what. I will be using this truck for off road use so i need it to be running as cool as poss.

Thank you in advance for your replys ..

I did away with the original fan on mine and used the twin kenlowe setup. I had a cut out switch to allow me to switch them off when wading.... you don't want them spraying water all over the dizzy.... and the water cools the rad anyway.

Mine was producing about 220bhp and never overheated, even sat in traffic.

the kenlowe fans should be alot better than the standard one for keeping the engine cool when running at slow speeds etc.
and of course i agree with the above about the water!

Land rovers are generally over cooled in a UK climate, so with normal running rarely need to use the fan for extra cooling. Although a viscous fan is better than a fixed fan (when not seized!), it's still taking power from the engine and using extra fuel. A Kenlowe (or other electric fan setup) makes a good backup if stuck in traffic on a hot day. If you are off-roading, as mentioned above, put in an overide switch.. Remember to periodically check it's operation to comfirm it's still working.

Hope this helps

I wired a tell-tale lamp so when the fans switched I could see they were working. Not a problem at night because the headlights dimmed when the fans cut in  :lol:

Advace has been taken on board and ill sort the fans out soon..

Kenlow fans will shift slightly more than HALF the air that a good viscous fan will move.  I was advised by a Kenlowe engineer NOT to fit their electric fans to my LSE but to replace the viscous fan, a new hub costs £50 compared to over £100 for Kenlowes.

A vicosu fan when locked up consumes between 3 and 5 Hp, that's 185 amps.  How many fans draw this much current? so haw many fans can have a comparable output?

Fair comment, but why do most modern cars use electric fans? I'm guessing the viscous fan is still consuming power even when 'unlocked' and the saving of fuel when using electric fans outweighs this. My electric fans never came on in normal road driving except after several minutes sat in traffic. And then they would cut out again after a minute or so. I found them amazingly efficient.

I put an electric fan on mine, and it was drawing loads of power. I have now put the viscous back on now but it is a pain when wading.

Most modern cars are designed to have an electrci fan in the system, so the size of the rad is bigger even for an engine much smaller than the Rover V8.  Plus of course many modern cars have their water pumps and drive belts facing the inner wing not the radiator grille, so a viscous fan would not be poissible.

As for the economy, well I've put a big electric on the TDi and I'm yet to be convinced it's made the slightest difference to the MPG :-k
