Visco for V740 B230F

Hallow!
I'm looking for the Visco for my V740 (1988 year) with B230F. The ventylator
is all the time turn on, so the car is so noisy, when the temperature of
engine is small ventylator is also turn on. It's turn on in cold and hot
engine.

Can I buy the new visco in internet? If You know some links please send me.

Thenks for all.

 

This link http://tinyurl.com/bpopg points to RockAuto's listing for the
viscous fan clutch for the 1988 740GLE. I don't know if the cheaper one is
as good as the more expensive one. I have had them last several years or go
bad within a year.

Since yours seems to be stuck, it may also be shaking the water pump. It is
better to replace it soon so it doesn't damage the water pump bearings.

Thx for answer!
The water pump is in good condition (I think),..the temperature of the
engine is normal in summer and in winter is in the same place (the
termometer indicate veritical,..its in half) the temperature of the engine
isn't depent of the season or weater or air temperature. So i think that the
cooling system is in good condition,...in interior now (in winter) i've got
hot so the water pump work so good.

The noisy is only from ventylator. When I hit the pedal of accelerate deep
into floor, my Volvo sounding like a jumbo-jet ) The ventylator works with
engine all the time and the noisy is very high. The mechnics said that all
is ok, with my engine (400 000 km), but only visco is brake down, and i must
repair it or change for new one.


Sorry for my english... )

 

Your english is *much* better than my polish! 8^)

Check the water pump shaft for wiggle, that's how you know if the
bearings are ok. Another option if you want a quiet fan is to replace
the engine driven one with an electric fan. 940s used a setup like this,
but plenty of good aftermarket ones are available.

 

I don't understand exactly. I can used electric fan from 940 ? But, this
model have had electric fan in B230 engines?? When I should put the gauge of
temperature to turn on the fan??
I think that the visco is good idea,but new in Poland is expensive (~$
130 ), so I looking for the cheaper one.

Please write me ones again about water pump,...what I must check!?

 

Yes 940's (at least here) use an electric primary fan behind the
radiator, the water pump pulley is simply bolted on with no fan or
viscous clutch. It's nice because it's quiet, but the engine driven fan
works fine. I don't know what temperature the fan comes on but
thermostats are available.


Can you find a scrap yard to get a used viscous clutch from? That would
be the cheap solution.

For the water pump, just grab the fan and wiggle it, if the shaft
wiggles in the bearing then the pump should be replaced.
