Hi Tim, are you sure the motor is getting a supply or is there a fault in
the fan control circuit? Have you disconnected the fan feed and tried a
direct 12v feed or at least checked the voltage getting to the fan ?

Kenlowe.

Burton do the smaller fan kits which include all the mounting brackets
plus the thermostat and temp probes for �80-�85+VAT.

Even the larger fan kits are under �130 so I'm pretty certain you
should be able to get a replacement fan for a lot less.

I've certainly seen the fans being sold on their own on Ebay.

Hmm, well this was what I got from Kenlowe for a replacement motor
today ..

PRICE �58.25 + �9.90 P&P + VAT = �80.07

I am checking what sort of trade discount I can swing (it could be
considered 'old stock' so we will see.

I've found a link to Spal fans and they do a complete rad mounted kit
for less than the price of the Kenlowe motor and have 'hermetically
sealed motors' which judging by the rust in this Kenlowe KLM 1708
model it isn't?

Yep, a later design Kenlowe was �120 or so he said.

Nothing on there at the moment and I need to get it MOT'd by the end
of the month (for road TAX). ;-(

The Kenlowe has a 5" diameter pancake motor driving a 12", 'rimmed'
fan. Because it's a bit bigger than the core size of the Escort rad I
fabricated a bracket (17+ years ago) to carry the fan just behind the
front grille and a couple of mill off the rad header / lower tank.

A smaller (< 260mm) 'blower' Spal (255 mm dia actually) should fit
onto the rad cores itself so I can do away with the bracket and it
should be more efficient.

The fan is triggered by a Fiesta fan switch set into a thermostat
housing I modified (turned a threaded mating collar to take the switch
and ally welded it into a new 'opened up' thermostat housing) and
switched by a fuse protected relay. In the 17+ years I think I've
replaced the thermal switch once but I think this is the second the
Kenlowe (they seem to seize up if left unused for a while?

The next job is to sort the white spoke wheels where on a couple the
paint must be flaking off inside and causing leaks .. ;-(

Because is hasn't been used for a while the two rear tyres have sat
'soft' and I will probably replace them. Finding 185R14 'Mud n Snow'
(or 'off road pattern) tyres isn't that easy (at the right price
anyway) ..

All the best ..

Hi Gio.

When I first started and let the car run I gave the fan a quick spin
because I'm used to finding it seized if left for a while. It was at
that point I discovered that this time it was seized badly. I
disconnected the fan switch connections so it didn't try to 'drive' a
seized fan.

I have since removed the whole motor / fan / bracket assembly from the
car, stripped it right down and found the 'sealed' motor completely
full of rust (brushes / comm in good nick though). Ok, it had 1991 on
it so I'm not complaining but I think that was my second Kenlowe so
might try something else (and probably cheaper) this time.

All the best ..

Funny enough we had a Rickman but the larger Space Ranger. That was
converted to Diesel via an old Ford P100 engine and gearbox. For simplicity
I opted to use a standard Ford electric fan and top hose (that had a built
in thermo switch) to activate the fan.
You must have quite a bit of room between the rad and the front of the
engine (or even in front of the rad and grill) so a visit to the local scrap
yard should give you a cheap replacement although of course you would have
to manufacture the appropriate brackets unless the Kenlow support bars could
be used.
