Viscous fan

Shortly to change the water pump on the 2.5 petrol and wondered if it's
possible, without too much hassle, to upgrade to a viscous fan. Noticed the
bits are available from Paddocks but wonder if it causes the fan to be too
far forward etc.

Call Paddocks and ask them, if they say it's fine but it's not, then
get a refund, probably easiest.

yes, but since I don't know the answer, that doesn't help you a lot.

I'd have thought that if paddocks are selling an "upgrade to a viscous
fan" kit then they'd be able to tell him if it'll fit. If he means
that paddocks sell the parts that should allow him to fit it but don't
sell them for that purpose, then he'd have to do some measuring.
Seems no-one else here at the moment has tried it.

How about a google groups search?

It's the second thing, Paddocks seem to sell the bits but I'm not sure it
would fit without a major redesign to the rad and cowling.
Can't believe it's not been tried before or does everyone just go the
electric fan route.
I'll try a Google search/phone Paddocks when I've got time and let you all
know.

Alright I give in......

Theoretically the viscous option is for aircon vehicles, but

there are two possible water pumps, depending on which alternator is
fitted, STC640 or STC635. You'd need one of these, a pulley ERC8890,
a fan ERR3380 and a viscous unit ERC5708, and some bolts and
a new fan belt ERC8938.

The problem is: does the belt line up with the crank pulley, or do
you need an aircon crank pulley - I don't know, but I'm sure
some 2.5P's escaped into the wild with viscous fans, so it
may.

Thank you Richard, the problem I now have is do I start the process only to
find the belt doesn't line up or simply leave well alone and go the
easier(?) electric fan route idc.
I tend to do quite short journeys of 2 to 3 miles, stop for an hour or so
and then return, so quick warm up is important in the winter.

This is your regular ride IIRC?

FWIW I'd be inclined to go the safe/tried/tested route.

Very cheap solution - blank off the radiator. Completely or partially,
your choice. It works.

You might even be able to consider removing the fan but that will
require more discipline.

Bearing in mind the price of the crank pulley (should you need it),
then the electric fan route is probably easier and cheaper. Personaly,
I'd keep the old fan and a spanner in the back though, in case the
electrics play up - but then I do use a belt and braces!
