Just a quick question to the experts out there - decided to fit electric cooling instead of the viscous fan - can anyone recommend a kit and or someone to fit it? I am sonewhat mechanically challenged - and this is even moreso with electrics... Embarassed

A friend of mine did this on his LR disco using twin fans from a citroen BX diesel, they even have a progressive controller so the second one doesn't cut in until a certain emp, worth a squint sown your local scrappy. I'm gonna fit another to my chevy as at the moment it only has a small electric from a jap.

If you want a ready made kit then Kenlowe or Pacet are both good brands.

I bought a Pacet kit complete with stat but was not happy with it at all. The temp probe fits inside the rad hose, it didn't leak but made me think it would! The stat was an open metal box of tricks which packed up the 1st time it went off road despite waterproofing it. The fan fixings went through the rad and over time wore the fins and started on the core.

I removed the stat & probe and fitted a straightforward on off switch for if it ever got hot. I also made a metal frame to fix the fan in to save the rad.

I have now removed it all together and fitted an unbranded brand new fan bought from a boot sale for £5 which is quieter and more powerful judging from the current draw!

I'd personally never use the through the rad pin type fixins, especially not on a 4x4 as inevitably they cause leaks. The fan on my Chevy is a scrapyard special fitted by the prvious owner and is bolted on although it does seem to cool adequately it is quite small and when I got it was not wired through a relay as I found one day after some time in traffic. There was that hot plastic smell, put my hand behnid the dash and the switch was roasting, the switch light used to glow as the fan windmilled in the airstream when off acting as a generator! Now wired via a relay and when the new intake manifold goes on I want to make a proper metal shroud for two decent spec fans and control them with a thermostatic switch mounted in the manifold.

I bet if you had a hunt around the scrappy with a tape measure you could find a complete fan/shroud unit thats a decent fit and just fab some mountings. thermostatic controllers can be either mounted in hose, a seperate unit thats like a hose joiner or get a radiator specialist to braze a threaded bung into the rad to mount one there. A manual overide for on/off is useful too, on when you hit traffic, off when you go through deep water to avoid spraying it around the engine compartment.

I'm interested in this topic too - have been quoted £147 inc VAT by PACET for a 16" fan which fits the engine side of the radiator and sucks air through, but that is self fitting.

Am still waiting for a reply from KENLOWE.

The Citroen twin fan sounds promising, must contact my local scarp yard!

Bigger the better for a petrol one! If you are going offroad remember to fit an over-ride switch to turn the fan off when going through water Idea

Reply from KENLOWE:-

Isuzu Trooper 2000 Model Citation

Thank you for your enquiry.

The equipment required is:-

16/SXX 16” suction fan (fits between radiator and engine) 12V 20.8A

PRICE £116.80 + £20.44 VAT = £137.24

KLM2216 30 amp Inline fuse & Holder

PRICE £1.50 + VAT £0.26 = £1.76

Price includes fittings, wiring, and automatic adjustable thermal control unit with sensor and comprehensive instructions for easy DIY installation

This will be suitable for solo road + off road use, towing up to 1.5 t any distance and local towing of heavier trailers (up to 100 miles). For long distance heavy towing, particularly in hot climates, viscous fan blade can be temporarily refitted. Use of quieter electric fan kit to replace the viscous fan will release power, save fuel.

Funny - the price I had from Kenlowe was twice that for my 3.1 Bighorn... and Pacet never got back to me!

"kenlowe" quoted me £291.87for a kit for my 3.1td twin 13in h/duty fans and would only guarantee it for towing up to 1.5 tons any distance any thing heavier for a 100 miles only
1 how come its cheaper for a 2000 citation
2 why wont it cool a diesel engine that already runs cool compared to petrol engines
3 at that price its definitely a do it your self job
any twin fan setup off a decent size petrol engine would do the job

I run a single *beep* electric fan from some japanese car with just a manual switch to put it on to cool a 5.7L petrol V8 with no problems so far, OK it doesn't get used every day but it's spent time in queues at car shows on very hot days with no problems. I can't see a twin 13" fan setup shifting less air than a single engine driven fan, especially as an engine driven fan is working at it's hardest when you need it least i.e. at speed when the ram air through the grille does all the cooling and working the least when you need it the most i.e. sat idling in traffic.

Has any one got any experiances to report ie I changed mine to an electric 1 and now get 5 mpg more

What set up did you use Magnatec? The theory is about right cos there is less drag at the front of the engine...so the engine does not have to work so hard to run itself

Sorry Stanners, I was interested to see if any had experianced improved economy etc and if they had what sort of increases they were getting, I have not done it to mine yet as I have only had it 1 day
