How to fit a Kenlowe fan
Moderators:Aceman, ecosselynx
Hi, I'm in the middle of fitting a Kenlowe to my 1961 Mk2. I know there are mixed views about the need for these fans, but I've tried flushing etc and still have to watch the temperature gauge carefully when stuck in traffic. My question is, how do you install one in 'blower' position, ie between the grill and the radiator? The rad cowl means there's only just enough clearance to slide the radiator down into the car, without a fan attached to it. As far as I can tell it's not an option to take off the grill and fit the electric fan with the radiator already in place, since you wouldn't be able to get the grill back on with the radiator in place. I want to keep my mechanical fan so a 'sucker' position isn't feasible. Thanks in advance for any advice.

I know its stating the obvious again, but after doing the usual cheap options of :-
fitting the correct radiator pressure cap.
Making sure you have the correct and working thermostat.
Making sure your water pump is on one peice and working.
Rather than just flushing the radiator, have a new core fitted to the top and bottom tanks, my local guy fitted a new 4 row rather than the standard 3 row core.
It is well known from research that at motorway speed air does not enter the front grill but has to be sucked it!
As to your original question, yes you can fit a pusher fan without removing the radiator.
At the bottom of the radiator entry space (just behind the bumper is a small rectangular plate), held on with two bolts in captive nuts. with this removed it it possible to get your arm up there and remove or replace the 4 nuts holding the grill on (I've done it and fitted a very large fan).
As you say it is not recommended by Ken Jenkins, but I fitted mine for hot climates and it came on quite often. Problems of the thermostat leaving it on and flattening the battery made me fit a manual switch in its place.
Old style cores and clogged cores are often the main cause of overheating................I'll leave others to rehash this into there own posts!!!

Hello Brian,
I agree, if the standard fan doesn't keep it cool in traffic there's a problem elsewhere.
"It is well known from research that at motorway speed air does not enter the front grill but has to be sucked it!"
It's not well known to me, where did that come from? It does sound rather unlikely also? One factor that affects airflow is the exit route out of the engine bay, perhaps the Coombe's car had bonnet louvers for that purpose? Aston Martin had a bonnet blow off a DB3, I think on the track and it immediately gained 300 revs, after that their cars had outlet vents from the engine bay.
