Question: Acura Tsx Timing Chain Tensioner?

How do you know if your timing chain tensioner is bad?

When a timing belt tensioner fails, it can result in a number of different symptoms.

  1. Symptom 1: Squealing, rattling, or chirping.
  2. Symptom 2: Knocking or slapping.
  3. Symptom 3: Check engine light illuminated.
  4. Materials Needed.
  5. Step 1: Park your vehicle and turn off the engine.

Can you drive a car with a bad timing chain tensioner?

The car will coast to a stop and need to be towed. Some engines power the water pump off the timing belt and have a belt tensioning pulley. If the engine design allows moving pistons to strike stationery open valves, failure of the belt, water pump, or tensioning system can destroy the engine.

How much does it cost to replace timing chain tensioner?

The average cost for timing chain tensioner replacement is between $906 and $1,108. Labor costs are estimated between $764 and $964 while parts are priced between $141 and $144.

When should a timing chain tensioner be replaced?

The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.

What causes timing chain tensioner failure?

The most common cause of timing chain stretch is lack of maintenance and regular oil changes. Worn out oil can no longer lubricate the chain and will cause the rollers and links to wear against each other. In some cases, a worn timing chain may cause the engine to jump time a few teeth.

What happens if timing chain tensioner breaks?

A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.

What happens if timing chain is off by one tooth?

Usually, off by one tooth is not all that critical, and you should not bend valves. You may have a bit more low rpm or a bit more high rpm responsiveness, depending on whether it’s advanced one tooth or retarded one tooth.

Do you have to remove engine to replace timing chain?

The simple answer is No, it is not. Timing chain problems are not uncommon, especially in high-mileage vehicles. Like any other moving mechanical component inside any engine, a timing chain is subject to wear. A timing chain is lubricated by the engine oil.
