Many owners are surprised to learn that their early ML's hood can actually be adjusted to go almost straight up. It is not as easy to do as some of the earlier models where you only had to flip a couple levers.

DO NOT neglect your W123 hood hinge and firewall corner drains. The problems plugged drains can create arre many and the 123 sedans, coupes and wagons are more prone to front plugged water drains than any other model.

In this video instruction Kent will walk you through the process of doing either a partial or a full flush of your W210 SLS system fluid, including some tips on how to make changing that little filter less frustrating.

In this video instruction, Kent will demonstrate how to check for one possible source of a mysterious front end clunking sound. Any clunking noise you hear when driving over rough ground or when braking should be investigated immediately.

In this long video manual Kent will walk you step-by-step through the process of removing the older square style leveling valve from your Mercedes, opening it up without losing the spring and balls, removing the old o-rings and cleaning the parts properly, installing the new o-rings, and putting

In this video Kent will walk you through the procedure of removing the old accumulators and installing new ones in a W123 300TD wagon. It is a very straightforward job that only takes a couple hours. You will need to raise the car and safely support it on jack stands.

These are the instructions that come with Kent's brake pad and brake caliper service kit. It is possible to make your own service kit by watching this video. To purchase the kit see related products below. To learn more about the importance of this kit watch the video below:

When replacing the front upper control arms you formost need to think about safety. You will need a good quality and large rolling hydraulic floor jack, and a couple good jack stands.

This instructional video covers the procedure for flushing the old hydraulic fluid out of an SLS system and installing new fluid. The example shown in this video is from a W126 560SEC.

This one hour long on demand video is included free with the purchase of Kent's OM61x injection pump timing kit. The method he teaches uses his own kit, his custom built pressure tank, and his special IP snake wrench.

Interior water leaks are becoming more common in the 123 chassis sedans, wagons and coupes. Kent believes the reasons are twofold. 1. The W123 is still used all over the world as a daily driver. Thus use, exposure to the elements and age = leaks. 2.

If you have a 1969 to 1985 4 or 5 cylinder diesel (except the 1984-85 190D) you may have already noticed it is hard to get the valve cover totally sealed from weeping oil stains coming out the bottom or top of the valve cover gasket.

When an engine is both overheating and losing coolant, you first want to exhaust all possibilities that the cause is something simple or inexpensive to repair. It is possible it might just be a stuck thermostat with a faulty water pump leaking coolant at the same time.

If a car has sat outside in the elements for long periods and has not been washed or waxed in months there are some things you need to do BEFORE you apply the buffer to the body and the final wax to the paint. This is where you will need some real "elbow grease."

In this video Kent covers the removal and replacement procedures for the sunroof air dam or otherwise known as the air deflector. Using a special technique and a plastic trim tool can prevent damage to the plastic clips. He also covers troubleshooting the reasons for improper operation.

Tilting power sunroof problems can be many. This is particularly true on roof mechanisms that have not received proper lubrication over the years. One of the first things that can fail is the power sunroof cable.

If your engine is just running hot, it may be due to a plugged radiator or possibly a stuck thermostat. If your engine is just losing coolant it could be a leak in the water pump, radiator or hoses.

In this video Kent will go through the process step-by-step of properly installing new air filters in your 500 series larger V8 models produced after 2000. If not done properly you can damage the engine cover and possibly the engine itself.
