Timing Chain Replacement
How much does a timing chain replacement cost?
It’s possible that, over time, the timing chain can stretch, the timing chain tensioner or guides may fail, or poor lubrication can cause wear on the timing chain itself.
If that happens, timing chain replacement is required. The average cost of replacement is $1,200 to $2,000+ depending on the car you drive.
What is a timing chain?
Like the chain on a bicycle, the timing chain connects gears together – the camshaft gear (or gears) and the crankshaft gear.
The timing chain is located behind the front engine cover and may incorporate the oil pump’s operation and the water pump’s function into its role.
Some vehicles might be equipped with more than one chain: a timing chain and balance shaft chains.
The solid links in a timing chain are meant to eliminate the need for replacement. If the timing chain has signs of wear or has a rattling noise, it should be replaced immediately.
What are the symptoms of a timing chain going bad?
These are the symptoms you need to look out for when you think your car's timing chain needs to be replaced:
- Rattling noise from the front of the engine area
- Check engine light illuminated with timing-related codes
- Rough running condition
- Excessive fuel consumption
- Poor power or hesitation when driving
- Stalling or stumbling at idle
How is the timing chain replaced?
The engine accessories are removed, the engine oil is drained, and the front engine cover is removed.
The tension on the timing chain tensioner is released and the camshaft and crankshaft gears are removed along with the timing chain, the technician will also use specialist tools to ensure the engine timing is still aligned while the timing chain is removed.
The new timing chain is installed on the gears, and the gears and chain are re-installed in the same position.
The front cover is re-installed, the accessories are mounted, and the engine oil is topped up. Lastly, the technician runs the engine and road tests to confirm the repair is successful.
When should a timing chain be replaced?
The timing chain may last the lifetime of the vehicle. So unless the vehicle manufacturer has a specific replacement interval or you notice any of the symptoms of failure you may not need to get it replaced. However, if you do notice any symptoms of failure it is important to get the timing chain inspected as soon as possible as costly engine damage can occur.
How important is a timing chain replacement?
If there’s a problem with your timing chain, it could cause further running issues at any time. Stalling, rough running, and hesitation can be hard to predict and dangerous while driving.
If the timing chain breaks, the damage will be much more expensive than only a timing chain replacement.
