Belt Tensioner & Pulley

This automotive maintenance tutorial was specifically written to assist owners of the 2014, 2015 and 2016 NMS (new midsize sedan) VW Passat TSI in changing the serpentine accessory belt on the turbocharged 1.8 liter inline four cylinder engine.

Owners of other VW Group vehicles such as the Beetle, CC, Tiguan, Golf, Touareg, Jetta, GTI, SportWagen, Eos, Rabbit, Bora, Vento, Lavida, Coccinelle, Maggiolino, Fusca, Audi A3, A4, S4, A6, S6, A7, A8, Q5, Q7, A5, S5, and TT may also find these DIY instructions to be helpful.

A few compatible replacement belts with their part numbers include the following: Bando 6PK1100, ContiTech PK060434, Bando 6PK1100B and Volkswagen 06J 260 849 F.

The tools required to complete this procedure include a 16mm socket and a 3/8" drive ratchet.

A/C Compressor Pulley

Crankshaft Pulley
The first two steps are to open the hood and then move to the left (passenger) side of the engine bay.

Take a moment to study how the original OEM belt is routed around the various pulleys including the alternator, tensioner, HVAC (A.K.A. A/C or air conditioner) system compressor and the crankshaft.

Study Belt Routing

Push Down Ratchet
Locate the tensioner pulley which is situated next to the crankshaft pulley and below the alternator.

There is an arrow on the tensioner assembly that indicates which way the tensioner arm should move to release the tension on the belt.

Place the 16mm socket or a 16mm wrench on to the bolt head located at the middle of the tensioner pulley.

Slip Belt Off Alternator

Remove Old OEM Belt
Firmly push the end of the wrench or ratchet down towards the bottom of the engine.

The tensioner assembly should rotate up and release the tension on the old belt.

Hold the wrench handle down with one hand and slip the old belt off the alternator pulley.

I recommend buying the OEM (original equipment manufacturer) Volkswagen 06J 260 849 F serpentine belt.

Lower the new belt down in to the engine bay.

A good rule to remember is that the grooved (or ribbed) side of the belt gets routed around ribbed pulleys and the smooth side of the belt goes against smooth pulleys.

Begin by wrapping the new belt around the large crankshaft pulley, then around the A/C compressor pulley, under the tensioner pulley and hold the last loop near the alternator pulley at the top.

Place the 16mm socket and ratchet on the tensioner pulley and rotate the wrench down towards the floor.

Hold the tensioner arm in the released position with one hand while you slip the new belt over the top of the alternator pulley.

Check Belt Routing

Start Engine - Listen
Double check that the new belt is routed properly.

Start the engine and listen for any strange sounds that might indicate an improperly routed belt or a faulty tensioner assembly.

If you do hear any strange noises, immediately turn off the engine and check your routing and the tension on the new belt.

Be sure to record the belt change in your car's service records.
