AC,

Try to have the tension of your belts adjusted by your suking mekaniko. Goodluck.

pajerokid... kaya nga eh... dami tumitingin... kakahiya tuloy paminsan... hehehe...

roydok... try ko yun tnx

[afrasay]

Change mo na belts mo. It's a sign.

hey, NEVER apply WD40 on your belts.

these are lubricants and will cause more squeaking. imbes na kumapit yung beld me sa pulley eh lalong dudulas.

There are available spray type BELT CONDITIONERS sa mga Handyman or truevalue shops. these are more appropriately used than WD40s.

tnx alfrasay n juno... try ko muna tighten before replace sayang eh)

Try mo muna belt dressing before tightening the tensioners. Kapag hinigpitan mo baka lalo bumigay in a shorter period of time since nababatak lalo yung belts.

[artpogi]

Tama si RS, try mo Belt Dressing ng 3M.

Nalimutan ko lang yung presyo kung magkano, bibili din ako nun.

Bumili ako nitong belt dressing. Buti binasa ko muna..... bawal daw sya sa mga serpentine belts..... buti nai-exchange item ko pa.

Dear AC:

I too have experienced squeaking or squealing on start up.

This has happened with many of our cars, past and present.

Frequently it's one of the fanbelts, but sometimes its the airconditioner tensioner bearing.

Also the noise frequently disappears when the engine heats up.

The best way to test if its the airconditioner bearing is to spray WD-40 onto the bearing cover and if the squeak stops then you have the cause.

The reason is that the grease in the bearing flows when warm and stops the squeak.

If you suspect the fanbelt, temporarily remove it and the squeal should disappear.

When replacing the v-belt, go for a toothed belt as replacement as it is more efficient, stronger and will last longer than a solid belt.

Lastly, most people over-tighten their fan-belts or v-belts, that will destroy your bearings, the belt should be just tight enough not to slip, any tighter reduces bearing life.

I myself have not replaced my fanbelts for 8 years now - see what happens with proper adjustment.
