Rb20 Belts

[tiesto]

hi

today driving home i noticed my car smelling a bit odd like a rubbery burning smell and i've checked all the belts and they seem fine, like none loose.. so i let my car idle a bit more and it sounds a bit weird then i get a screeching sound and the idle changes again, then the screech sound goes and idle goes back to normal.. and continuining to get an odd rubbery smell coming from around the radiator

anyone know what could be the problem? the belts seem fine so i'm not sure what else to check?

any advice would be appreciated

thanks

edit i just started it up again and it makes the screechin sound from when you start it so i moved the car a bit and it sounds definately like a belt

but the two belts ive got are both fairly tight, maybe too tight? should there be any play within the belt?

Have you got the air con on?

And yes there should be a certain amount of deflextion in the belt.

5mm deflection in either direction. Look for slip marks on the belt face and backing. Also while your there check from cracks in the ribs. Easiest way to do this is to look at the belt where it goes back on itself, like when the backing is around an idler pulley.

BTW if a belt is too tight it will sing not screech. Also you should have 3 belts, as previously mentioned if the aircon is on it will place extra load on that belt when the compressor kicks in so that will possibly make it slip.
