I have owned my Discovery for about 2 months now and have heard this squeaking in the mornings when letting the car warm up a bit.

Thanks

If the drive belt is the least bit slack, it will tend to skid and SQUEAL right after a cold start because the load and DRAG on the Alternator is very high as it tries to keep the system voltage up to par, about 14 volts or so.

Once the battery voltage is up, the alternator has less work to to, so the drag is less, and it tends not to skid and squeal.

I just used a washer instead.

The washers are 8 pence each

tighten back up, put belt back on.

It's unfair for us living in Euroland as we don't have that part readily available ...

what is the thickness of a penny ? (in metric units of course)

that would be 3.2 millimeters ! I'm not sure the Euro coin itself is thick enough

how do you prevent your pockets from piercing with such coins ? (well, I remember the old pence, one felt rich with the weight of only a dozen

)

The UK penny measures 1.65mm-1.70mm-the euro 1 cent small copper coin measures~1.63mm-so very similar,although smaller in diameter.hth

Well I fixed mine with a US penny so I reckon my fix was about 40% cheaper than yours ;-)

I recently bought a Land rover Discovery 1 and had the same squeaking problem, until I saw the "penny trick" posts, by "Battenberg and " The mad Hat Man". I have just tried that trick out, but with a slightly thinner brass washer, and "Hey Presto" no more squeaking! Thanks so much for these and other really helpful posts.
This really is a great forum and you guys make garage mechanics seem irrelevant!
Cheers.

Worked for me too! Thanks

dilligat · May 20, 2012

Worked for me thanks,
Changed tensioner bearing last week with no effect and the water pump the week before when doing the timing belt.
I can only assume the belt runs at and angle across the tensioner pulley face causing the squeek and this mod lines it all up. The belt can't jump off as the grooved pulleys either side of the tensioner are so close and hold the belt in line.
Fingers crossed it lasts

Hi all,

I'd just like to add my "thanks" for this tip as well. My 300tdi developed a squeak and after changing the belt (it was due a change anyway) which made no difference I then tried swapping the tensioner. This seemed to work for a few days but then it came back.

I then stumbled upon this post! Curiously it didn't work on the new tensioner but in a flash of inspiration I took the old one down from the shelf (tip - never throw anything away) and tried putting the penny behind this one and hey-presto, silence has returned.

My theory as to why it sounds like the water pump squeaking (I was all-but ready to buy a new water pump) is that this is closest to the tensioner so if the tensioner isn't quite 'true' it'll be the next pully along that is affected the most.

Many many thanks,

Steve

ha yehup i bought a new water pump when i had a squeal i bought a new tentioner im lucky its quiet for two years but will definately try the penny trick
