Any electric fan to cool a Land Cruiser engine (if removing the engine-driven unit to do it) is not an upgrade, rather it's a serious down-grade.
I cant see the reason for doing the mod. All my cruisers OEM cooling systems work fine in 40c heat.John
i got the idea from the dodge cummins forum where it is generally considered an upgrade for summer towing and off road conditions.
i can see some disadvantages.
to demanding for the alternator
there must be more that i'm missing, please elaborate.
Oh, boy.... do I have to include caveats with every explanation ?Your point about clutched fans not robbing power is a bit of a half truth, anytime the clutch is engaged it is robbing power
I tested mine in low range,in thick soft sand in 2nd gear low range with 40 psi inthe tyres. The heat radiating off the sand is an added load.The engine got to 94c and then dropped off to mid 80sa situation where an electric fan could be superior, is 40C climbing "off road" a long steep hill, your rpm's are low so the clutch fan is not turning that fast for effective air flow, in this situation i would think an electric fan would make for a more efficient cooling.
The pics I have look like it has a viscous fan but Im not 100% on that.out of curiosity, on the new diesel land cruisers do they use electric fans?
.0000000002 cents LOL....
