In this 13-minute CIS training video, Kent will walk you through the steps recommended by Mercedes Benz to fully test the operation of the EHA valve on 1984 to 1993 4, 6, and 8-cylinder engines with KE-jetronic fuel injection.
This high-quality meter can test all types of automotive electrical circuits, but Kent has discovered it is particularly well suited for testing Bosch KE jetronic fuel injection components on those CIS models from 1984 to 1993. Extra adapter fittings are included as shown.

After completing the pressure test on your CIS engine, you discover a problem. But how can you find out how to isolate and fix it? This is going to require some research on your part. Start by learning how the system works and how each component plays a part.
In this video, you will see how the gauges are hooked up to a 560SL and how the pressures are read. The length of this 30-minute shows the detail Kent has put into filming all the critical components of doing a KE-Jetronic fuel system pressure test.
This video is specific to K- jetronic fuel-injected engines from 1976 to 1985. This includes the 350, 450, and 280 engines in the R107, W116, W123, and early W126 gas Mercedes. In this 29-minute video. Kent will show you how to hook up the gauge, run the fuel pumps, and complete the test.
There are a few factory recommend procedures and tests you should do before you do an actual pressure test on a CIS fuel-injected engine. In this 20-minute training video, Kent will walk you through these procedures step-by-step.
To do proper system testing on CIS fuel injection, you must find a way to get the fuel pump or fuel pumps to run continuously without the engine running. This can not be done by just using the ignition key. In this 15-minute training video, Kent will show the options available to do this.
This video will help you decide if you want to try to do a fuel pressure test yourself. It is a fairly simple DIY job but will all the confusion and misinformation on the internet; one would believe it is a complicated process that is hard to understand.

We modify this wrench right here in our shop. If a picture is worth a thousand words, what is a video work. Watch the following for a full explanation.
Why change K-jet injectors when "they are working?" Why change shocks when they feel ike "they are working." The deteration is very slow over time and you may not notice the difference in how the engine starts, runs, accelerates, and delivers mileage until you do this service!
Upgraded top seals for better and longer-lasting sealing properties and well as standard green seals for the bottom of the injector holder. With these seals you can clean and reuse your existing fuel injector holders / sleeves.
Damage to these is becomming more common as they engines age. If your fuel injectors are not firing fuel properly the ends of the prechambers cac burn right off causing all sorts of "weird" engine performance problems.
This is a high-quality ACM aftermarket part. The fan runs smooth and air movement is very strong.
Contamintion in the window washer fluid tank is one of the main reasons the spray nozzles get plugged up. Install this little fitler somewhere in the line between the pump and the nozzles on the hood and secure with zip ties.

Is your old gas engine running a little rough? There could be lots of reasons for this but if you have good compression, good plugs and wires you might consider replacing your O2 sensor even if your warning light is not showing up. This is an easy DIY job.
This is a part that hardly ever gets changed, and it is an easy DIY job if you can access it under your Benz. Make sure your model fits those described and has an O2 sensor installed. You can confirm that by the existence of an o2 sensor warning light on your dash.
This fits all Mercedes V8 engines listed in the title from 1981 to 1991 including the sedans, the SL and SEC models. I compare fan clutches to shock absorbers. They wear out slowly over time and you don't feel or see the difference until you actually replace it with new.
