(do it with the engine still cold, in the morning. it's less painful this way.)

I already tried pero it seems nakasagad na yung adjustment

siguro nga time to replace the belt. 3 years old na rin kasi. ganon ba ang normal lifespan ng belts?

Ooopppss! I keep saying 220km is the travel distance to Butuan... I actually meant 120kms only.

Sorry 'bout that.

kahit 80 kph puwede pa yan.

!st time pa lang naman marinig mo yan di ba? So hindi pa siya masyadong maluwang or pudpod.

Nope. First time I heard it was about 6 months ago, then I had it adjusted in the casa. It stopped squealing/screeching after that.

Then it started making that noise again probably 2-3weeks ago, mildly at first but getting louder now. But it does stop after a few moments.

I don't use the A/C nowadays because of this.

UPDATE:

I just had the belt replaced today by our friendly neighborhood mechanic. I couldn't wait for the 2 weeks the Butuan casa said it needed to order the belt from Manila.

And they couldn't even tell if the part is available in Manila!

The replacement belt was Dayco (4PK-1240) that cost 480pesos.
Anyway, I hope the belt holds up, at least until I get hold of an OEM Toyota belt.

^3 years na rin naman yang belt mo. IMO sulit na rin yan. Next time ka na bumili kapag may squelling sound na ulit. Maa-adjust pa naman siya ulit. But if may time ka makapunta sa casa, pwede din namang bumili ka na if may budget. Sa belts ng aircon, power steering at radiator fan hindi naman kelangan lagi na OEM. IMO sa mga timing belts lang mahirap mag-tipid.

But if kaya nga ng budget, OEM na.

^correct! Timing belts should always be OEM.

According to the Toyota website FAQ, the Yaris utilize timing chain, instead of timing belts.

Here's the link for the FAQ:

But I agree that for cars with timing belts, OEM parts should be used.
