How much does it cost to replace a timing chain kit?
Replacing the timing chain is a complicated job, and the labor costs can be quite high. For most cars, a timing chain replacement costs between $413 and $1040, or you can order the parts themselves for $88 and $245.
How long do timing chain guides last?
between 40,000 and 100,000 miles
The metal links in the chain move on the tooth sprockets on the end of the crankshaft and crankshaft so that they rotate together. The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem.
When do you Know Your timing chain needs to be replaced?
Signs your timing chain needs to be replaced include: Your vehicle has a rough idle, meaning your engine shakes. Your car backfires. The vehicle seems to be working harder than normal. Your car will not start at all, indicated a complete timing chain failure.
What causes a cam sprocket to rotate on a timing chain?
The chain tensioner (2) attempts to take up the excess slack in the timing chain. When the tensioner piston extends, the chain is pulled tight. Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank.
What happens when you remove the slack on the timing chain?
Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank. Rotating one cam sprocket disturbs valve timing relative to the other side of the engine. This can cause a rough idle can set diagnostic trouble code (DTC) P0300 and codes for lean and rich operation.
Why is my timing chain making a noise?
If the engine is equipped with a hydraulic timing chain tensioner, the noise may disappear or lessen as the engine oil warms up and the tensioner removes some of the slack. If the timing chain wear is great enough so the tensioner can no longer compensate for the slack, the noise may continue even after warming up.
