Fan on 95 325is |
|
|
My car has not been driving as smoothly as normal so I open up the hood
to find that the fan is missing about half of its blades. The have
snapped off somehow. My question is this: Is it dangerous to drive
the car like this? And how could this have happened? Also, is this a
big job to have fixed? Thanks...

This is not uncommon to see. The heat will weaken the plastic blades over
a period of time. This is something that you should have repaired
immediately, since it can take out the bearings on your waterpump. This
is not a major repair. A shop should be able to do it in a half hour. |

Not sure about your model, but on mine you remove the top half of the
radiator shroud. Easily done.

You can get a new fan from the dealer for about $60 (USD) and install it
yourself. I was doing a routine oil change when I found several of the
blades scattered about the engine bay ...
There is a single reverse-thread nut on the center of the fan that holds it
on. I forget the torque spec, but it isn't very high, and I took mine off
with channel lock pliers and used a screw driver to hold it still while
working the nut.

The thread on the fan is reverse so that when the engine is running it
drives the threads tighter. The "official" spec is 40nm (29 lb/ft).
You really do not need to tighten that fan coupling much. It only makes
it more difficult to remove the next time.

Not on the E36. The fan shroud goes all the way around and is easier to
remove after the fan is off. To remove the fan is just a matter of
getting in there with the right wrench and knocking the nut loose
(clockwise) from the top. It's a tight squeeze but can be done.
The easiest way to get it started off is to actually strike the (long)
wrench using a hammer or mallet with a sharp blow . It should spin off
easily after that. Then you have to finagle it out from between the
engine and radiator (shroud).

It was pretty easy, actually. Take the shroud off, and you can get to the
fan pretty easily. I don't recall if I did mine from the top or the bottom,
but whichever is easiest is the way I went.

I simply give it a tap with the hammer on the spanner - same as when
undoing it.

In the UK, Sykes- Pickavant sell a special spanner for fan removal. It's
in either the common sizes - 32mm and IIRC 34mm. It's made out of thick
pressed steel and has an offset before the jaw to clear the fan. It's long
enough to clear the top of the fan and housing making it easy to hit with
a hammer. Costs about 10 gbp retail, so much less than a full sized one
which is unlikely to be long enough anyway.

Yes but when struck with the hammer isnt the fan going to move? How do
you hold it in place when trying to loosen the nut? |

It's not the fan the nut is attached to but the waterpump. And it
shouldn't be very tight. It works by IIRC kinetic action. Think an air
wrech on a wheel - you don't need to apply the brakes.

You don't need to - although you might need several goes.

Don't take the belt off until the fan is loose or off.

Doesn't what turn both ways? You are trying to remove the female
threaded nut which the end of the fan clutch assembly from the male
threaded end of the waterpump.
