Oil Cooler and Seal Replacement - C Class - W204 - Mercedes-Benz


Oil Cooler and Seal Replacement Time: 1 hour Tab: $10 Talent: 2 Tools: T30 Torx, torque wrench Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Oil cooler seal Hot Tip: Clean both surfaces well Performance Gain: No leaks Complementary Modification: Oil and filter change The oil filter housing has an oil to water cooler attached to it to help cool the engine oil. While this simple design does a great job of helping control the engine oil temperature it has a tendency to develop leaks over time. This is usually caused by the seal drying out and installing a new seal usually solves the problem. You will need to drain the coolant from the radiator as the coolant flows through the cooler and needs to be removed before you can replace the seal. Please see our article on coolant drain and flush. If your oil cooler is leaking it is probably the seal; this article will show you how to replace it Applies to: C350 (2007-14), SLK350 (2004-14), CLS350 (2004-14), CLK350 (2005-14), E350 (2005-14), S350 (2005-14), SL350 (2005-14), R350 (2006-14), ML350 (2006-14), Viano (2005-14), Sprinter (2006-14), CLC350 (2008-14), GLK350 (2008-12)

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...
