[E-Type] Scott fans, Ron Davis radiators etc

I bought a Scott fan last year, along with a Ron Davis radiator for my 63 S1
car. It was recommended to me my by the supplier that I bolt the fan directly
to the fiberglass shroud and NOT mount it through the radiator. It made a
pretty neat installation.

I then tried to install my stock lower radiator hose, with elbow etc. It
seems like the lower pipe of the radiator has its turn-u so close to the
shroud that there’s interference. By the time I put the short adapter-type
straight section on, its upper part is so badly distorted when I install the
elbow that it just doesn’t look like the kind of thing I’d want to drive very
far-if at all.

Also, the lower mounting bolt for the Scott fan rubs right against the lower
hose.

The supplier called me today in response to my call for help. They say:

  1. I should mount the fan to the radiator, not the shroud. (the guy who told
    me the right way was to the shroud is gone now).

  2. Forget using the factory lower hose and buy a 20 inch long corrugated hose.
    Don’t use the elbow or other lower hoses.

I don’t really mind not being stock if it makes sense-Comments anyone who’s
been through this?

I have the Ron Davis all aluminum radiator and mounted a 15" fan through the
radiator. I also have the 3 piece lower hose and metal pipe combination installed,
no problems. With a 160F thermostat, installed correctly, thank you Dan, my
daily driving in Phoenix’s 105
F + air tempertures is as follows. At highway
speeds the water guage reads 70C. (Sometimes as high as 74C) In stop and go
traffic, remember its 105F+, I turn on the fan with a manual switch and keep the
guage reading under 90
C. In the evening when the air tempertures lowers to 90F
the guage will read 66
C at highway speeds. I do plan on installing metal upper &
lower radiator hoses, Summit catalog, and there is a high volumn water pump
available that requires machine work to install, but may not go that route. I
have done a lot of research and work on XK engine overheating. Early writings of
Jaguar indicated overheating during engine development was common. Main items to
consider if an overheating problem occurs. 1. engine timing, 2. carbs not adjusted
correctly, 3. Wrong fuel and or oil. After these items are checked, then the
common items can be checked, radiator, water pump, slipping belt, heater core
plugged etc. Ron Davis products are top notch and only perform when the car is
doing 35+MPH. If I can drive my car daily in Phoenix traffic, and report the
above engine temps, then you can too. (20W50 oil and an MSD system really help)

I have a 4.2 which is slightly different, but was able to mount the fan to
the shroud. It did require some trimming of the shroud near the lower hose
fitting for clearance. It was necessary to mount the fan to the shroud using
spacers to place the fan closer to the radiator and for the fan motor to
clear the old Jaguar fan motor bracket on the picture frame. The plastic
brackets accompanying the fan provided about 1 inch clearance (fan inside of
shroud and toward the radiator. I wired the fan to the standard Otter switch
and used the standard Jaguar piping.

Thanks Mike-did you have to trim the shroud?

Best Regards,

Should have mentioned the fact that I have no shroud except around the
fan blades that came with the fan, a rather simple set up. I have the
orginal shroud, radiator and square bodied fans, hard to say what I will
ever do with them.

The problem with mounting through the rad core is that the plastic ties can rub
through the tubes. If your fan doesn’t mount this way, never mind.

Corrugated hoses are always straining to go straight and could cause the neck on
the rad to loosen.

Is there a Ron Davis web site?

I couldn’t find a Ron Davis site, but I found RON DAVIS! Nice ghuy. I
called him in Phoenix this afternoon and he does not like those plastic nails
in his radiators. He said (based on my description) he would mount it to the
shroud, as I have done.

Mike,

Go to your local auto parts store and get a GATES #20145 radiator hose.
I have been using this one piece hose on my 3.8L S1 E as a replacement
for the Jaguar multi piece abortion lower hose for more than 15 years
with no problem. Nice thing about it is you can get it anywhere in a
pinch. You can replace virtually every hose in the cooling system with a
readily available GATES replacement from some other applicaton. I am
also using a Ron Davis radiator but with a fan mounted on an aluminum
shroud that is an integral part of the radiator. Came as a complete
assembly from RD. Works great!!
