FAQs

Where is the serpentine belt routing diagram? ›

Where can I find a belt routing diagram for my engine? 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.

Most Mercedes-Benz's have 1 or 2 drive belts and in some instances, it may be called a serpentine belt. The belt needs to be flexible to circulate across pulleys and can be made out of perishable compositions like rubber, neoprene or urethane.

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.

Your timing belt should be replaced anywhere from 40,000 to 60,000 miles and your serpentine belt should be replaced anywhere from 30,000 to 60,000 miles. We recommend consulting your owner's manual for Mercedes-Benz year, model, and trim specifications.

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.

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.

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.

How much does it cost to replace a serpentine belt on a Mercedes? ›

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.

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.

What Does a Serpentine Belt Do? As we mentioned early, a serpentine belt delivers power to your alternator, power steering pump, and air conditioning compressor. In some cases, it also supplies power to your water pump. It's a long, winding rubber band of sorts that is attached to your crank pulley.

If the belt is already out of place, locate the driver's manual or the under-the-hood placard, where you'll find a sketch of the routing.

Check if the belt runs centrally on the pulleys. Any sideward movement or slippage can indicate misalignment. Straightedge or String Line: Place a straightedge or taut string along the faces of the pulleys to see if they line up perfectly. Any deviation from a straight line suggests angular or parallel misalignment.

To do this, the belt has to be twisted 90 degrees. Twist it one way, and drive it from the appropriate side, and it'll go one way; twist it the other way, so you can drive it from t'other side, and it will go in the opposite direction.
