907.0. "Ford 2.0 Litre DOHC engine" by COMICS::HWILLIAMS () Fri Jan 05 1990 13:57

I wonder if any of you have come across this problem or perhaps heard of
someone who has:....

I have recently taken delivery of a Ford Sierra GLS. Its got the new ford
engine in it,  ie. the Double Overhead Cam 2.0 litre 4 cylinder unit.

The problem I'm experiencing is alternator & water pump drive belt slip 
(historically known as the Fan belt) when the engine is cold or wet.
You instantly know when its slipping 'coz it make an horrible screeching sound.
It happens especially when changing down through the gears, or when you place
torque resistance in the alternator by switching on any gizzmos (eg window
demisters...)

I'm already on my second belt and the garage have adjusted it twice, but its
still as bad. 
 Having a look at it the other day there seems to be a design problem, in that
although the belt is of a poly-V design for increased contact area, the angle
of wrap-around of the belt around the drive pulley on the end of the crankshaft 
is so shallow as to be useless.  A segment of only about a tenth of the
circumference of the drive pulley is actually in contact with the belt.

A colleague of mine is also experiencing similar probs. 
The engine came out in July 89, and is available is both carburetted and
injected versions. It is used by Ford in both the Sierra and Granada.

Any comments or history of other sufferers would be appreciated, Thanks,

Huw Williams.

907.1Not a technical answer, but...UKCSSE::YOUNGFri Jan 05 1990 15:2613
    
    Are you a member of the Ford Talkback scheme?
    
    If you are ring them. They are seem to be very helpful to company car
    drivers.
    
    Alternatively bend the leasing companies ear. I did this when
    I had a problem getting a persistent fault on my GLS fixed. They
    insisted that Zenith Reading (Groan) call in Ford troubleshooters.
    Ford fixed it in 30 minutes.

907.2it's just one of those thingsBONNET::HARDYThu Jan 11 1990 07:5213
    This seems to be fairly common.
     
    It happened for six years on my XR2, but after the first five you
    get used to it. During that time I used to hear the same noise
    from other cars, particullarly when they were pulling away from
    standstill in the wet (at first, it sounds like a clutch problem).
                                                                   
    Let us know if you find a cure.

907.3Bigger is not always bestCOMICS::HWILLIAMSWed Feb 07 1990 12:5822
    to set the record straight................
    
    I took the car in again to the ford main dealer and they placed a new
    fan belt (this was the 3rd)  and a new alternator bracket (apparently
    the original was the wrong one!!??) 
    
    BUT! this made no difference whatsoever.
    SO in desperation I took it to an another Ford agent (Not a main
    dealer) And because the outfit was small I talked to the mechanic
    direct.
     He borrowed a ford parts micrfiche and listed against my model were
    two fanbelts, one 2.5cm longer than the other!
     So he ordered and fitted the shorter one (now the 4th to be fitted in
    2 months) and cleaned the grooves on the pulley ('coz they had filled
    up with burnt rubber due to the slipping)
    
    AND NOW IT NO LONGER SLIPS!!  (muted hooray)
    
    So the underdog shines through!!  I restrain from commenting on the
    main dealer.
