Hi all, Has anyone of you any experience in changing the mechanical cooling fan for an electronically one? I was standing in a big traffic jam yesterday for 11 km, with 30 degrees C. and the cooling system could not really cope with that kind of circumstances, so I am thinking of changing the fan. I hope to get some technical info on how to do it and where to buy such a fan. Thanks in advance for your advice.
Carel

You could always get a Kenlowe fan kit or similar, but to my mind its a lot of messing about. You best bet is to buy a bottle of Red Line Waterwetter and add to the cooling water and provided that your cooling system is in good order, your problems will be solved !

I was plagued for years with my 3 litre overheating but when stuck in traffic in France in 2003 the gauge only crept up almost to the top whilst others were boiling around me - in temperatures of 45 deg C! It was HOT. After considering an electronic fan at length, all I had done was change the radiator to THREE cores and uprate the water pump to a six-bladed impeller. And the proof of the pudding is in the eating.

A good clean preferably 3 cored rad is the best solution with possibly the original fan removed and an automatic electric fan.
I get no problems with overheating in mine with the standard fan and a 3 core rad. The standard 2 core is marginal especially if partially silted up and there is a worn mechanical fuel pump as fuel vaporisation arises. Modern petrol burns hotter than the old 5 star apparently so some form of upgrade is required for reliability

Hi all,
Thanks for your advice. I will first order Water Wetter if its possible from Holland and afterward look for a bigger radiator. By the way, this board is really a great help for a person like me, who is just new with the P5b. I also solved the problem with my gearbox, gear change to late, through this board.
Regards, Carel

Isn't another factor that if you replace with an electric fan and unhook the belt-driven fan, you can save horsepower? I've read that can be 10-15 hp, but I guess that depends on the situation.
Has anyone done this?

If your cooling system is up to scratch this is the valid reason for fitting an electric fan as its only needed in traffic. I have not done this but others have with success

I have fitted a PACET electric cooling fan with thermostat to the front of my uprated radiator and removed the engine driven fan - infact I did all this several years ago and have had no overheating at all. I must admit that my only problems were in standing traffic when the temperature would rise to what I would say was 'my' limit but since the conversion I have had no more problems. Also, engine noise is reduced, some power is saved and starting from cold, the engine warms up more quickly all in all its a WIN WIN upgrade.
I can highly recommend doing it. Adrian

I have a kenlowe fan, but I bought a control thermostat from Mg Owners club - its an aluminium collar that fits into the top radiator hose and is a lot neater than the horrible kenlowe thermostat.

I fitted Citroen CX fan, Being a very slim design It fits ahead of the radiator between the grill and rad. I had a sender from a Peogeot 209 fitted to the rad, this being to lowest kick in temperature I could obtain. I have removed the belt driven fan which does give alot better access to the front of the engine when doing timming and similar jobs. Copes well in summer even in the high temps we have had in UK and of course winter the car warms up much quicker. Cost about £10 all bits being 2nd hand. John Stacey Bristol UK

However, the sensor was not very effective so I fitted a Kenlowe themostatic switch assembly (sensor bulb into radiator top hose with an adjustable temp control - very effective) I wired the fan supply via a relay to the starter motor supply.

After thinking it over for some time I decided to put in an electronic fan, Today a garage did put in a Kenlowe heavy duty fan. I works wonderfull with the adjustable temperature button. I kept the old fan in case the new one will brake down. I will always have a backup in this way.

I decided to give the Kenlowe fan constant electric feeding so it will go on working for a while after the engine is stopped.

Hi, Mike here in Norwich. Where can I get a bottle of 'red line waterwetter' in the UK ? The web site only quotes American suppliers. THX

i was thinking about adding a kenlow fan to mine but also keeping the nornmal fan as well. i already have a 16" fan which i took of my Pajero before i sold it. I was thinking about mounting it in frount of the rad behind the grill what do you think???

What are my learned and experienced club colleagues´ opinions towards an extra coolant header tank? Second hand from a Range Rover, Land Rover, or Rover SD1 (all with 3.5 litre V8s)? There is enough space for the header tank on the right side of the radiator. Onewould have to take off the filler cap on the radiator, connect the radiator with the header tank by means of a permanent hose, and put the filler cap on top of the header tank. As overheating problems mostly occur while traffic is standing still (and not for too long) it would save you the expensive and complicated to mount Kenlowes and give you the reassuring feeling that you´re not running out of water while you´re in the thick of it.

Why tinker with the problem? Why not tackle it straight on. If the car overheats, put a THREE-core radiator in.

Absolutely - its the rad that the problem - use electric cooling fans if you are dispensing with the engine one to save fuel and reduce noise.
Use SEARCH for more opinions!
Water Wetter can be had from Holdens
