Timing belt vs Timing chain

[Gallago]

At that time I was part of the Stealership Cult. One of the last ones I did was at Independent RMI accredited mechanic. Dont have his details.

I dont have the answer. Both my current cars have chain timing belts, I would probably try to do it myself with the help of a good friend that think doing stuff like that is fun.

Yea now i just checked my 90k service interval invoice Belt service was carried out worth Kit belt of R2590, now at 135K they are telling me to replace a Timing chain, now im not sure if my car uses Chain or belt.

Fairly sure it has a timing chain. The belts that were replaced drive the alternator, a/c etc.

Sure Bro, Who can i use around CT to Change Timing Chain for Sandero T900, Renault is asking for alot that i thought of selling the car.if you know a good Mechanic please hala.

Kosie swanepoel developments in Stikland. They are top quality work.

My Touareg uses a timing chain, my wife's Q3 uses a timing belt, my MkI Golf also uses a belt and the '66 T1 Bus I own with a friend has timing gears.

Used to prefer chains when they were at the front of the engine at the radiator side, now all the cars comes with timing chains on the rear which is a pain, a full engine out job just to change the chains and the guides.

My 3.0TDI (lucky its the facelift version so the chain issues were fixed) has a chain rattle at start up but it last for like 2 to 3 seconds, Audi says its normal as the hydraulic tensioners needs oil pressure to build in order to tighten the chain, gonna get the chain and guides changed before my warranty expires though cause its a mission of a job and not to mention not easy on the wallet.

My friend had a F30 316i that had the timing chain stretch outside warranty got a quote for R83 000.00 from BMW, She managed to sell the car and now drives a G20 320D

I can highly recommend Bradley from Ren-o-Worx in Stikland.
Let him check the car out and then decide.
The 0.9t engine is supposed to have a "lifetime timing chain", so not a service item and only replaced when something is wrong/broken.

What mileage does it have?
On most vehicles the chain is a lifetime part, it should never need to be replaced.

Renault wanted me to replace it for12k

Timing chains suffer from wear and tear and need replacing on a regular basis. My wife's spark was due to have it's chain replaced at the next service (150k).

Yes. Current car has a timing chain.

When I was looking at upgrading to a VW Group car again, it had to be equipped with a 3.0 TDI engine, because the 2.0 TDI uses a belt. That said, due to lax personnel at the dealership, my dad's Polo 1.9 TDI skipped its 90 000 km belt change, and only had one done on 180 000 km... still looked fine (thankfully).

This is just my preference, though, because I don't want to worry about having the timing belt replaced every 90 000 / 120 000 km. There's also less chance of a timing chain snapping than some apprentice cocking up the timing when replacing a belt.

Family member bought a second hand 1.9TDi that had the belt replaced with what can only be described as a bunch of used condoms. It broke and cost said family member like R50k to get everything replaced. Why go through the trouble of replacing the belt and then cheaping out on the belt itself? When they bought the car, they were of course told that the timing belt was replaced recently, so it wasn't an item they had checked. School fees I suppose.

That really sucks. If not the branded belt, I stand and fall by Gates.

I probably should have said “on most Japanese vehicles”.

A well designed timing chain system with regular oil changes typically means they last the life of the engine, it’s only when idiots like BMW and others start making timing chain guides out of plastic and similar that they become wear items needing regular replacement.

I thought everyone uses nylon for timing chain guides. What do the japs use?

The guide part that actually connects to the chain itself to tension it will be some kind of engineering plastic like nylon and held in a metal frame but on many modern BMW motors and a few other manufacturers to save costs they started making the entire guide including the frame out of plastic which resulted in catastrophic failures due to the plastic disintegrating and the entire thing breaking up into pieces and destroying the engine. Also for some reason they seem to wear out faster, apparently without the metal frame they are more prone to oscillation and other issues with vibration.

Does BMW still make the guides out of plastic in their latest engines?

I don’t know, I think it’s model dependent, probably best to Google whichever BMW model you are interested in and check for known issues.

I forgot to post my experience last month: The timing belt on my Toyota Camry snapped while driving at speed. Fortunately it's a non-interference engine, so there was no permanent damage (after replacing the belt and idler).

What had me a bit puzzled was that I had not driven excessive distance since the last change. The technician explained that the belt deteriorates with age (like a tyre sidewall).

I have been driving much less in recent years, and never considered this as a factor worth noting. I guess the same applies to wear items such as radiator hoses, suspension bushings, and exhaust silencers.

Yeah, those rubbery bits end up drying out (for lack of a better explanation) and then cracking, followed by breaking..
