Mercedes-Benz W123 And R107 DIY

The early Mercedes 450SL was fitted with the Bosch D-Jetronic, EFI or Electronic Fuel Injection system. While this blog post will not cover in detail the entirety of the D-Jet system, it will cover all the steps for a full removal in preparation for an inspection and refurbishing of the harness. This will be covered in a future article. It is a good idea if you own or are in the market for a Mercedes 450SL or any classic Mercedes, to either regularly inspect or throughly inspect the car respectively. As our cars age, much of the rubber, plastic, and wiring is in poor condition and needs to be either replaced or repaired. Don't risk a fire! Removing the EFI - D-Jet wiring, is not complicated, does not require any special tools, but will require some physical contortion. As is indicated throughout the car used for this blog is a 1975 450SL. The wiring will vary depending on chassis series. Remove air cleaner and the plug to the air temp sensor.

While in the process, check the seal on the underside of the air cleaner housing. This is the seal between the air cleaner and throttle body. This seal is still available from Mercedes-Benz. TIP: When purchasing a new seal, make sure it is for the D-Jet. The later K-Jet will not fit. Label every wire and take photos before removing any thing. I use masking tape looped around the wire and stuck to itself with a piece long enough to write on with a Sharpie. Unplug the wires from their respective terminals but leave harness in place. Water Temp. Sensor and Auxiliary Fan Sensor (Shown: 1975 450SL) NOTE: Depending on the chassis series, the Aux. Fan Sensor and driver side manifold temp sensor were wired independently from the main harness. Remove the lower passenger side footwell dash panels and locate the ECU under the dash as shown in photo below. Remove the lower spring clip by pulling down on it. The hinge of the clip is attached to the firewall. Once the lower clip is removed, gently wiggle the ECU back and forth while pulling down to release the flanged retaining peg from the upper bracket. When the ECU is free, remove the plastic harness plug guard (not shown) and the wiring harness retention collar (illustrated below) to release the harness wire and unplug the harness. Illustration above shows how the ECU is held in place. Unplug both relay connectors and single line plug. Should one of your plug housings break, they are available from Mercedes. Release the rubber grommet from the firewall. It will more than likely not survive the removal and will require renewal. 80. NOTE: It is not necessary but will make the job easier to remove the valve cover. With help, pull the wire through the firewall. It is best to have one person in the car guiding while the other pulls from the engine bay side.

The folks at Mercedes-Benz HQ in Stuttgart truly have no regard whatsoever for automotive naming convention. Not only are there four doors plus a hatchback on the GLC Coupe, but it is not even a car鈥? So what do we really have here? Let鈥檚 start with Mercedes鈥?recently introduced GLC mid-sized SUV. A well designed and engineered vehicle getting a substantial amount of kudos from the automotive press. Now let鈥檚 chop the rear roofline down and lower the thing a bit in the name of sport and style. Actually, I place much blame on MB鈥檚 rival, BMW. A while back, BMW created this sport SUV niche with the creation of the X6, based on their 鈥渘ormal鈥?X5 SUV. Mercedes followed with their GLE Coupe, based on the GLE SUV. BMW fires back with the X4, based on the mid-sized X3. MB now returns fire with the GLC Coupe. There will be two flavors of the GLC Coupe, the first being the 4-cylinder powered base model with 241-hp and 273 lb-ft of torque. This is the same engine proliferating the C-Class and GLC lineup. A 9-speed transmission shifts the gears, driving the 4Matic all-wheel drive. All of the usual Mercedes tech bits are either standard or can be had with a check of the right boxes on the order form. The next step up in performance will be the AMG GLC 43 (pictured), from the Benz performance wing. This will bump you up to a V6 biturbo engine spitting out 362-hp, 384 lb-ft of torque, and several speeding tickets鈥? GLC Coupe interior bits are lifted from the C-Class and GLC, meaning you get one of the best driving environments in the class. To my eyes the GLC Coupe is the best realization of this aesthetically challenged class of SUV, certainly better proportioned than their larger GLE Coupe. I suspect you will see a sampling of this new buggy at your favorite high-profile valet stand in the near future.
