How to Install a Belt Tensioner on a 2.7L Engine on Chrysler 300?

First, attach the tensioner bolt to the tensioner and tighten it to 34 Nm (40 ft. lbs.). Once you have chosen the right belt, install it, ensuring the tensioner includes two things: an indexing tang at the back and an indexing stop on its housing. If you're installing a new belt, place the tang within approximately 6 - 8mm (0.24 - 0.32 in.) of one of the indexing stops, so both designated indexing stops are on opposite ends of the tang. A belt is new if it has been used for no more than 15 minutes. Be sure to examine the belt indexing notches.

How to Service and Repair a Belt Tensioner on Chrysler 300?

It is essential to confirm the indexing tang on the back of the tensioner and the indexing stop located on the tensioner body before starting service. The proper position for the tang during installation is within about 6 - 8 millimeters (0.24 - 0.32 inches) of the indexing stop, where a new belt refers to one used for 15 minutes or fewer. If the requirement is not met, check your belt for the proper length or width, worn bearings on accessories such as the A/C compressor, power steering pump, water pump, idler pulley or generator, belts not installed properly, loose pulleys or incorrect belt routes. If it's time to replace your belt, the tensioner indexing arrow should have reached the minimum signal, because the tensioner will not travel any further. Remove the accessory drive belt, making sure you don't dismantle anything due to the strong spring pressure of the automatic tensioner, because it's all serviced as a unit except for the pulley on the tensioner. After that, get rid of the bolt holding the assembly to the mounting bracket, along with the tensioner assembly. Unlock and rotate the tensioner before putting the bolt into the accessory pulley, hand-tightening it to 34 Nm (40 ft. lbs.). Then place the drive belt and verify the positions of the belt's indexing points.
