Mercedes W204 Belt Diagram (2024)

FAQs

How do you find the serpentine belt diagram? ›

A: Commonly a belt routing diagram sticker is on the underside of the hood or in the engine compartment. If there is no diagram, make a sketch of the belt and pulleys before removing the belt. This will help you re-route the new belt correctly.

The Mercedes-Benz C-Class (W204) is the third generation of the Mercedes-Benz C-Class. It was manufactured and marketed by Mercedes-Benz in sedan/saloon (2007–2014), station wagon/estate (2008–2014) and coupé (2011–2015) bodystyles, with styling by Karlheinz Bauer and Peter Pfeiffer.

Serpentine belts usually last about 50,000 miles or five years, or in some cases, even up to 100,000 miles. Your belt should be inspected at 50,000 miles, as this is often when you start to see the belt material breaking down.

Are Serpentine Belts Directional? Because nearly all serpentine belts are symmetrical, a new belt's direction of rotation usually doesn't matter. What does matter, though, is that the new belt is routed correctly around the pulleys. It's also important that the grooved side of the belt faces toward the pulley grooves.

EXAMPLE: 6PK1003 » 6 - This indicates the number of ribs on the belt; therefore, this is a 6-rib belt. » PK – The “P” indicates a metric designation, and the “K” indicates the belt is automotive per SAE J1459. » 1003 - This is the effective length of the belt expressed in millimeters.

Always consult an owners guide for the proper tension range. You should always use a Belt Tension Tool and refer to the manufacturer's specs for each belt. Now for reality, you don't have one… A good “Rule of Thumb,” seek approximately ½ Inch of deflection for a V-belt.

A loose belt can also lead to premature failure of the belt itself, as well as the bearings. For this reason, it's important to watch out for common signs of a loose belt to avoid belt slippage and misalignment. These signs can include: Belt cracking or pieces breaking off.

Press down on the belt so that it deflects until the bottom of the large o-ring aligns with the top of the adjacent belt. This sets the gauge at the calculated deflection distance. Release the pressure. The upper small o-ring moves on the scale to point at the force (tension) created by the deflection.

When it comes to picking the best Mercedes-Benz C-Class variant, it would hands down have to be the C 220d. This is the entry-level diesel offering, and is offered with a 2.0-litre diesel engine. While the higher diesel variant also gets a 2.0-litre engine, it's tuned to make a lot more power and torque.

The reliability has been really good with only the common faults really being an issue for me: 1 Fuel injector gave in and stopped partially working putting the car in limp mode.

Are Mercedes reliable after 100k miles? ›

While 100,000 miles used to be regarded as high mileage, hitting six digits no longer means your vehicle is at the end of its life. Today, thanks to advances in technology, many Mercedes-Benz vehicles can last well beyond the 100,000-mile mark with proper care.

The serpentine replacement interval is about every 60,000 – 100,000 miles. Because of their rubber material, serpentine belts will crack, peel, and wear down over time.

Labor costs are estimated between $54 and $68 while parts are priced between $43 and $75. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.

You can find the correct size of serpentine belt for your car in the owner's manual or by using an online belt sizing tool. If you are unsure about the size of the serpentine belt you need, it is best to consult a mechanic or an auto parts store.

Most vehicles nowadays usually have a belt routing sticker located somewhere in the engine compartment, making it even easier.

How To Identify a V-Belt Pulley. The easiest way to identify a V-belt pulley is by finding the part number or identification components on the pulley itself. Different brands, as well as different pulley types, have various ways they may display these numbers.

Turn off the engine and remove the serpentine belt. Shake and spin each pulley to check if there is excessive play or noise. Any play or back-and-forth movement indicates a bad pulley bearing.
