What vehicles does this Gates tensioner assembly fit?

This tensioner assembly is designed for Mercedes-Benz vehicles with the V-6 3.5L engine. It specifically fits model years from 2013-2016 for the E350, and covers a wide range of other C-Class, E-Class, GLK, ML, and SLK models within that engine family.

Should I replace the belt when I replace the tensioner?

It's generally recommended to replace the accessory drive belt at the same time you replace the tensioner. This ensures the new belt is under correct tension from the start and avoids potential issues if the old belt is worn or if the tensioner fails soon after belt replacement.

What happens if the belt tensioner fails?

A failing belt tensioner can cause the accessory drive belt to become loose, leading to slippage. This can result in noise, premature belt wear, and loss of function for components driven by the belt, such as the alternator, power steering pump, or air conditioning compressor.

Product Details

This is the Gates belt drive tensioner assembly, part number 39212. What you get in the box is the tensioner unit itself, designed to keep your accessory drive belt properly tightened. This is crucial because a loose belt can slip, leading to issues with your alternator, power steering pump, or A/C compressor. This tensioner assembly fits a wide range of Mercedes-Benz vehicles with the V-6 3.5L engine, including models like the C350, E350, and ML350.

A properly functioning tensioner is important for the longevity of your accessory belt and the components it drives. Over time, tensioners can weaken or seize, causing premature belt wear or noise. Gates is a well-known name in belt systems, and this assembly is built to meet the demands of your vehicle's accessory drive. It's designed to fit right, making installation straightforward for a mechanic.

When you're replacing your accessory belt, it's often a good idea to replace the tensioner at the same time. This ensures that the new belt is operating under the correct tension from the start and avoids having to do the job twice if the old tensioner fails shortly after. Always refer to your vehicle's service manual for specific installation procedures.
