knocking sound + timing belt

itarumaa

Hi,

any ideas what is the cause of the problem. Every time I turn sharply (90 degrees) to left or right, I can hear a knocking sound from the suspension.

Car is Daewoo Matiz.

Also does someone know what is the timing belt change limit with the same car, internet says 36k (honestjohn.co.uk), owner changed it on 40k but manual says 60k. I am a bit confused what would be the right info.

The turning could be your CV (Constant Velocity) Joints. - These can be changed easily.

About the timing belt, well it really depends on the car. My MG ZS is every 60,000 or 5 years I think, which ever comes first.

I know the timing belt depens from the car, but should I trust the manual or the internet, that is the problem,

the current belt has changed around 34k (miles) before.

I personally would trust the manual as it was made for the car (Assuming you have the correct manual for the correct model/litre engine!)

What's the car out of curiosity - you sure you have the exact same engine/spec as the ones on honestjohn etc.

For timing belt I'd go by whats in the manual, after all its what the maufacturers who know the car best recommend.

Just looking at numbers is is possible one is kilometeres and one is miles as 36 miles is nearly 60 km. Might just want to check that out.

I double check the manual and maybe open the timing belt cover and check the belt myself.

The car is Daewoo Matiz, year 99, 798cc.

Yeah - well, like Gillo says, the manufacturers know best so stick with them.
Even if it was 40k, you would want to be very unlucky if it were to snap before 60 or even 80k. It just a precaution

+1 on this it sounds like your CV joints. With the TB it does vary a bit for manufacturers but is very important to do it as stated as most engines but not all can be severely damaged if it snaps!

Hi just to tell you, in the manual this is mentioned, timing belt needs to be changed at 40 000 miles or 60 000 km.

So both internet and manual were right this time:)

Mr.Diagnostic

It might be worth checking with a dealer regarding the timing belt interval because manufacturers often revise their recommendations.

I think I will drive the car trough summer and then it can retire to nearest scrap yard with rest of the Korean junk:)

Ok, one more question,

if I would go ahead and change the timing belt and cv joint, can someone give an estimate how much it would cost?

I am thinking 150e for cv joint and 200-250e for belt, would this be correct?
