Coolant Pump Replacement - C Class - W204 - Mercedes-Benz


Coolant Pump Replacement Time: 3 hours Tab: $100 to $500 Talent: 3 Tools: E12, E10 Torx, 17mm socket, flathead screwdriver Applicable Models: Mercedes-Benz C350 (2007-14) Mercedes-Benz CLK350 (2006-09) Mercedes-Benz E350 (2006-14) Mercedes-Benz GLK350 (2010-12) Mercedes-Benz ML350 (2006-14) Mercedes-Benz R350 (2006-12) Mercedes-Benz S350 (2006, 2012-13) Mercedes-Benz SLK350 (2005-14) Parts Required: New water pump and gasket Hot Tip: Keep track of where the bolts go Performance Gain: Properly cooled engine Complementary Modification: Replace your radiator hoses When a water pump begins to fail, you'll notice that the car tends to overheat at low engine speed, such as sitting at a stoplight. When you accelerate, the engine temperature will drop. Now, this is not always indicative of a water pump, but a good starting point. You may also want to try squeezing the top radiator hose with the engine warmed up and running. You should feel pressure build up on the back of the hose and surge once it is released. If you feel no pressure, it's a fair bet that the water pump is failing. You are going to need to drain the coolant to replace the water pump. New coolants can last a long time so if your coolant is good there is no need to replace it. Just make sure you drain it into a clean container and you can reuse it. If your coolant is old or failing this would be a good time to give the system a flush. Please see our article on draining and flushing your coolant system. Replacing the water or coolant pump on the W204 is certainly a doable job for a DIY'er but if this is one of the first projects you are attempting on your car, give yourself at least four hours to get the job done. Don't forget to refill and bleed the coolant. Figure 1 You need to remove the front engine cover (red arrow) and the air ducts (yellow arrows) to replace the coolant hoses so please see our article on engine cover removal for additional assistance.

Crankshaft Positioning Sensor Replacement - C Class - W204 - Mercedes-Benz Crankshaft Positioning Sensor Replacement Time: 2 hours Tab: $20 to $40 Talent: 1 Tools: T30 Torx Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Crankshaft positioning sensor Hot Tip: Use a mirror Performance Gain: Smoother running car Complementary Modification: Replace Camshaft positioning sensors Your fuel injection computer (DME) may output a code that indicates a faulty camshaft position sensor (CPS). This important sensor tells the car's computer where the flywheel is located in relation to the combustion cycle. The DME takes the signals from both the cam position sensor and crankshaft position sensor, and calculates when to fire the fuel injectors and spark plugs. If the crankshaft position sensor is not operating properly, your car will run very erratically or perhaps not at all. Replacement of the sensor is not as easy as the camshaf...

Unfortunately, the rubber bushings on the stabilizer on the W204 are vulcanized to the bar and cannot be replaced separately. This means you will need to drop the bar and replace it with a new one. All of the mounting hardware is considered single use so make sure you order new hardware when ordering the bar. You will need to jack up the car and remove the front wheels along with the under body trays to perform...
