What is the purpose of the tensioner used with a timing chain?

Consequently, the timing chain tensioner is a device that places the necessary tension or pressure on the chain to allow it to control the timing chain properly. It usually performs this function through spring tension or hydraulic pressure.

Why does my timing chain make a rattling noise?

Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover. 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.

What to do if your timing chain tensioner is not working?

Once you have taken off the bolt the timing chain tensioner will just be sitting there. All you have to do is pull the timing chain tensioner out and get the new one and if you want rub some oil on the new one to lubricate it – although this is not essential!

What to look for when replacing timing chain?

When replacing the timing chain, it’s important that the accessory belt, tensioner, idler pulleys, and water pump are inspected as these components wear at a similar rate. These components are inexpensive when compared to labor costs.

What to do when your timing belt loosens?

To release pressure from the system, turn the tensioner away from the belt. Depending on your vehicle’s setup, you may need to turn it clockwise or counterclockwise. Rotate it until you notice the timing belt loosen and begin to slip off the tensioner. Always turn off the vehicle before adjusting the tensioner.

Where is the timing chain tensioner on a Death Rattle?

Above the crankshaft bolt you will find the timing chain cover held on by four 10mm bolts. Pop the cover off and you will see the timing chain tensioner. Stick a pin into that chain link looking thing and remove the two 10mm bolts.

Why do I need to replace my timing chain tensioner?

The timing chain tensioner is responsible for keeping the proper tension on you timing chains. It does this by keeping constant pressure on the guide rail. If you are starting to get chain noises from the engine, especially on cold start ups you should inspect or replace the tensioner right away.

Where is the timing chain on a T-sb-0041-13?

Turn the crank 10° counterclockwise to give some slack to the timing chain. You can then remove the top timing chain guide with the 12mm bolt. Above the crankshaft bolt you will find the timing chain cover held on by four 10mm bolts. Pop the cover off and you will see the timing chain tensioner.

How to fix a T-sb-0041-13 cold start Death Rattle?

Use the TSB diagram to find TDC. Then, paint it yellow with a paint pen. Turn the crank 10° counterclockwise to give some slack to the timing chain. You can then remove the top timing chain guide with the 12mm bolt. Above the crankshaft bolt you will find the timing chain cover held on by four 10mm bolts.
