Intake Manifold Removal - C Class - W204 - Mercedes-Benz


Intake Manifold Removal Time: 4 hours Tab: $10 Talent: 3 Tools: T30 Torx, E10 Torx, 17mm wrench, small flathead screwdriver Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Gaskets, white lithium grease, O-rings Hot Tip: Clean around the runners before removing Performance Gain: Fix problems with the manifold Complementary Modification: Replace worn out hoses There are several common problems that need to be eventually fixed with the EGR and swirl flaps on the Mercedes intake manifold. Unfortunately, you need to remove the complete manifold to access the repairs. While it is possible to remove the intake manifold without removing the injectors and fuel rail it is only a few extra steps to pull the injectors. Doing so will give you a little more room and less things for the wiring to get hung up on when you are removing the manifold. If you want to leave the injectors in place simply skip the step of pulling the rail and injectors. If you are going to be opening the fuel line on the motor the first step is to prep the car. I like to tell people to pull the fuel pump relay and then try to start the car. The car will turn over and then die. Do this about two to three times. Doing so will help drain excess fuel out of your system. Also open the gas cap to help depressurize the system. Then, make sure that the car has cooled down; you don't want to be working with gasoline when the car is hot. Have a fire extinguisher handy. There will be some spillage of fuel as it's nearly impossible to prevent. Also, wear chemical resistant gloves if you don't want to get any gasoline on your hands, and make sure that you have plenty of paper towels or rags to help you clean up. Perform the injector removal in a clear, open, and well-ventilated space. It may not hurt to have an assistant around in case there are any problems. You are going to be pulling the injectors out from the manifold so make sure to clean around the area and blow it out with compressed air so you do not get dirt down into the injector openings. Removing the intake manifold is not a quick job but it is made easier with these step by step instructions 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)

Tumble Flap Actuator Repair - C Class - W204 - Mercedes-Benz Tumble Flap Actuator Repair Time: 1 hour Tab: $300 Talent: 1 Tools: T30 Torx, small flathead screwdriver Applicable Models: Mercedes-Benz C350 (2008-14) Mercedes-Benz GLK350 (2010-14) Parts Required: Actuator repair kit, silicone grease, blue Loctite Hot Tip: Lube the ball cups Performance Gain: Better engine performance Complementary Modification: New injector O-rings Along with the variable intake runners on the intake manifold on the Mercedes C350 the manifold also has tumble flaps. These tumble flaps on each side of the intake help swirl the air entering the combustion chamber helping with performance and economy. While the system works reasonably well, over time carbon will build up on the flaps and cause more stress on the plastic actuator arm than the system was designed to handle. This usually results in the failure of the plastic pivot lever where it meets the actuator arm. If you drive the car long ...

All of the mounting hardware is considered single use so make sure you order new hardware when ordering the bar.
