Hey Guys,

There is this loud screaching noise when the car hasnt been started for a few hours or in the morning. Now i know the noise is coming from one of the recently replaced water pump, ac or power steering belts and goes away after a few seconds and stays quiet when im driving. Im thinking the mechanic either didnt tension the belt enough or to much? Or does this usually happen for the first few times with new belts once they are changed. Any feedback is appreciated thanks

Yeah its a belt. You can also buy a product from CRC i think, its a non slip sticky spray on stuff for belts. But you shouldnt need it. Just tighten them. Thats what i did when i had the exact same prob as you.

Thanks for the reply guys, its my regular mechanic so they will no doubt fix it for free i just thought maybe it would go away by itself after a while but looks like ye they didnt tighten it enough.

Thanks again

could also be caused by a small person caight in the engine bay. anytime you start the car it hurts so they scream.

That or a loose fan belt....tighten up the alternator adjuster

most probable that the belts have been put on too tight. U can adjust the tension in a few minutes with a shifter,

PM me for details on how to do this, I had this problem too when putting new belts on, they usually do it a bit tight to allow for stretching over time

Thanks for the feedback guys, i did adjust the alternator adjustment screw a little bit because i thought it was a little loose, then took it back to the mechanics and he said its fine because he didnt want to tighten it to much because it will put to much strain on the water pump and bearing if it was to tight. Maybe some grease or something got onto the belt while it was changed. Ill give it over the weekend to fix itself, if not back to the drawing board on monday i think hrmmm

ya same, my starter motor used to make a screeching noise only when it was cold. i took her out and slapped some grease in, hasnt done it since.

might even be the starter motor

mine was makn a screachin noise, still havent got it fixed.

  • 4 months later...

hey guys, im having the same issue atm with this. I put some no slip spray on it and this stopped the noise from happening as much, but it only lasted about a week or 2...

can anyone point me in the right direction of what screw i need to tighten, with maybe an image or something? Or where to locate it, any help would be awesome

As someone said they stretch over time. So when you first put them on, and adjust them to the right tension, they shoudl be all good, then as they over the next couple of hundred k's, you redadjust them again.

How does grease help the problem? I can see how grease would stop the noise (by lubricating), but I can't see the grease making the belt "grip" the pulley better. Unless it gets absorbed into the rubber over time and moistens it up or something?????? Kind of like, when you drive with wet shoes, it's slippery at first, but after it starts drying out it gets to a REALLY grippy stage....

Avoid using belt grip sprays.. they usually dont do much if anything at all.

If the belt is tensioned enough get a stick of dri-lube, and run it along the belt (carefully!) while the engine is idling until the noise stops.

Even the slightest bit of grease off the mechanics hands, while fitting, is enough to make the belt noisy.

If you can twist the belt about 3/4 of a turn is a good place to start and very very small adjustments until it stops making the noise.

Check out what a tight belt will do and i have done a OEM and N1 in the same way.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
