When I start my car from cold I get a slight belt squeak. (Car is a 2007 S/C). Once the car has been running for a few minutes it goes away.

I'm a bit sh*t when it comes to mechanics, but it sounds like it's the lower of the two belts as I look under the bonnet. I did put a little squirt of WD40 down there a week or so ago, and the squeak went immediately, but it came back very quickly.


Is this something I can adjust myself? (Given that I'm about one grade above a monkey with a spanner).  Past (too many to list, but a few favs)...

You should NEVER spray WD40 on rubber belts as it deteriorates them, spray a little water on them to identify if that is the source of the squeak

i suffered this problem back in oct 2010 of the squeaky belt noise on start up. "Stratstone" changed Fead Belt PQR500320, idler Pulley PQR500350 and a modification to the mounting bracket, Bottom front crank seals, The pulley, shim and nut. The Bill £720 but Cured the problem.

For £720 I can live with a few moments of squeak on start up!  Past (too many to list, but a few favs)...
