How often do I need to replace the timing chain?

Question

I now you are supposed to replace the timing chain every 90k miles on Hondas and Toyotas, but how often on other vehicles?

Answer 1

I have a toyota corolla 98 and it came with a timing chain. I also have a buick Century 87 and it also came with a timing chain.

As far as I know for Cars, U dont have to worry about Timing chain if the millage are bellow 200 k. After that, u should have it inspected by mechanic and let them tell u whats best.

Chains are the BEST. If u dont abuse ur car/truck, Chain should last Cars lifetime

Timing Chain Replacement

Answer 3

Some Hondas and Toyotas have interference engines and some don't. Bottom Contributor is wrong in saying that they are all non-interference engines.

Also, regarding single row timing chains, Saturn S series chains are recommended to be changed at about 200k, if that. It's mostly the plastic track that wears out a bit. The chain itself, if the oil was maintained properly, will look and measure nearly like a new one. Generally, when they wear past the limit of the tensioner, you'll start to hear a clattering sound. Occasionally they have been known to break without warning. Other Saturn S series owners said that they drove their Saturns way past 200k with no chain issues.
Saturn S series engines are interference engines, so if the chain breaks, you will bend valves.

The 1990 Honda Civic we once had we drove up to 266k miles before someone stole it. It always had its original timing belt. Recommendations for the particular year didn't mention a change interval, but said to keep it properly tensioned, which I did occasionally, by loosening the tensioner, and allowing it to take up slack, and then tightening it again.

Eventually a timing belt can become fatigued enough to snap, but it is actually far more important to keep slack out of the system. The usual failure in an otherwise properly designed system, where the belt and bearings are of good design, is for the belt to jump a tooth because of too much slack from stretching. Once the belt skips a tooth and the valve train stops, the drive sprocket will tear apart the belt. As long as good tension is maintained, and the belt doesn't jump, the belt will likely run a very long time before breaking.

Answer 4

When To Replace Timing Chain

Answer 5

Or timing belt! Those don't last as long. It varies from car to car. It matters what vehicles you are talking about. The shortest I have heard is 35k on daewoo engines. http://www.daewootech.com/forum/viewtopic.php?t=8123 That includes the new Chevy Aveos, because they have Daewoo engines. Some engines have what is nicknamed "interfence motors", and that is where if the timing belt breaks, the valves will hit the pistons, effectivly destroying the top end of the engine! I used to work with someone who had a New Chevy Aveo that broke the T-belt at 85k miles! It destroyed the whole top of the engine, and he had the whole thing rebuilt. And the car was less than 2 years old. It had the original belt. Most V8's the timing chain will outlast the engine, ecept that it will slack badly.

In short: it varies from car to car, on interference motors, I wouldn't risk waiting.

Answer 7

There are three different kinds of timing "chains". There are timing belts made of rubber that need to be changed every 60K to 80K. There are timing chains that use a single row chain that need to be changed every 100K and then there are the double row chains that if maintained with frequent oil changes should never have to be replaced. So you need to know what system is used in the vehicle you are talking about.

Answer 8

Timing chain or timing belt? Big difference. I think you mean timing belt. This is a vague question which I will give a vague answer. Each make year, make and model have there own suggested timing belt change intervals. Too many variations to list!

A timing chain should last the life of the engine. Anyone who says different is confused.

Answer 10

every time you do an oil change you should be inspecting the timing belt for cracking or weathering or abnormal wear. Now if it has 90k and never changed you should do it and put a water pump in it and idler belt pulley if the timing belt requires one while your in there. Otherwise you will have to go back after those things later on.
