If you want to fix the engine fan motor or reduce the bearing noise, this is how you can do it for a little over $200. You don't need to replace the entire engine fan assembly, and you don't have to resort to buying a used one from eBay!
Good used working (tested) sunroof motor and rubber drive bushing as shown.
Here you see it mounted on a W115 plate. The plates vary, but all motors are the same.
Enter the dreaded “check engine” light. When it suddenly comes on it can create fear and panic in many a driver. Kent has known some people who have sold their cars cheap because they just did not want to deal with taking the car into a mechanic to get it fixed.
Good ground cable as shown. Even includes good tightening bolt.
Set of good working switches for your 300TD wagon. Wood is not the best but could be used if yours is worse. Some cracks in the clear coat and a couple chips as shown.
A 12 volt test light is a very handy tool to have when working on any car but it is particularly important if you have a old diesel. This tool will allow you to quickly determine if there is power getting to your glow plugs, and if not where the power is breaking down.
Good ground cable as shown. You will need to supply your own bolt
When replacing the steering lock assembly in your Benz you will need to remove that little black plastic switch on the side of the lock from the old one and put it on the new part. You can not pry it off, squeeze it off or pull it off by hand.
Tired of lugging around heavy batteries or battery boosters to test electrical components in your car? It does not have to be a Mercedes. It does not even have to be a car. Anything that runs off 12 volt DC power can be tested by these small, light weight but very powerful batteries.
Electric power seats are great if they are working ok. When they do not work - especially in the fore and aft or tilt movement it can be very frustrating to even drive the car.
If your power seat is not working it is hard to determine if it is a switch, a motor under or inside the seat, or a wiring problem. From our experience xx % of the time the problem is in a worn out or failed electrical seat switch.
If your rear door power window is not moving or the motor is not making any noise, it could be a failed motor, rear door switch, front switch or even a wiring problem. Trying to narrow down the problem can be frustrating unless you know the proper troubleshooting sequence.
THESE ARE GENUINE BOSCH. Do not purchase the cheaper aftermarket regulators as we have found they do not last. This voltage regulator that bolts on to the back of your alternator. This is the common failure point and when it does you will not be getting any charge to your battery.
New fuse box fuse location sheet as shown. Please note there are some slight varibles between different W116s so there may be some different wording, etc. from your original
The voltage regulator is a very inexpensive part that usually wears out between 110,000 to 130,000 miles. It is often neglected and Kent believes many alternators have been replaced over the years when all they needed was a $25 to $30 voltage regulator!!!
If your engine temperature gauge is not reading at all, you need to fix it before you keep driving the car. To ignore this could lead to major engine failure, since you will have no way to get an adequate warning that your engine is about to overheat.
This is another small "frustration" for W123 diesel owners. The fuse box cover is mounted flat to the firewall behind and to the left of the brake booster. You can not just pull it straight out nor can you just push it straight back on.
New voltage regulator to fit the following 201 and 124 models listed below from 1990 to 1995. No instructions included but not difficult to replace.
Fits the following

Works on most 116, early 107, 114, 115 and early 123 models from the early 70s up to the end of the 1970s. This is a replacement for the Bosch rectangular voltage regulator (see image below) those cars that use an internal voltage regulator.

W116 driver power window failure is very common. It happened to Kent's personal 1979 300SD.
Special price only 6 available. New Aftermarket Glow Plug Relay for models and years listing. PLEASE NOTE: cover is not included. You will have to use that from your old relay. Easy install. No instructions included.
Looking for better-staring performance? Are your glow system lights not coming on on your dash even after replacing the glow plugs? It it taking way too long for the glow light to go out ( it should only be on 5 to 10 seconds)?
Yes, there may be a fuse inside or outside your fuse box that controls your heater blower motor or another high amp draw electrical component. Most of the separate fuse holders require a 30 amp fuse. You may find a funny looking bent fuse inside your fuse box.
50 amp fuses were used on most 123 240D diesel glow plug systems due to the lower amp draw. 80 amp fuses will also work but some may choose to go with original spec. Check the number on the center of the fuse you are currently using. It should read either 50 or 80.
Tired of having to pull and hold the glow / starter knob on your old 110 or 115 chassis diesel? Hand getting tired? Waiting forever to get the glow plugs hot enough to start the engine? Wish the glow plugs would not burn out so often?
Fits chassis 116 123 126 124 and 201 Diesels with pencil glow plugs, from 1978 to 1989. This includes the OM617, OM601, OM602, and OM603 engines. They also work on 1977 to 1979 300D 300CD and 300TD with series glow plugs. This pack includes three individual fuses.

This is another small "frustration" for W123 diesel owners. The diesel requires a big and heavy battery that is not as easy to remove and replace as you would think. If you are not careful, you can tweak your lower back lifting one out of the car.
An annoying problem on many older Mercedes up to 1980 that have an aluminum housing surrounding the turn signal arm latching assembly. When these wear out the lever will not hold position when you push it up or down.
To many people, automotive electrical systems and testing are a big mystery. It is not as complicated as you might think.
When an old Mercedes ( or any other car for that matter ) has sat idle for over a year it can be a challenge to get it safely back on the road again. If it has sat idle for more than 5 years you may find it difficult to even get the engine running.
Malfunctioning and failed power window regulators (mechanisms) are so common on older Mercedes that Kent can almost guarantee if you own one and drive it regularly you will have to fix one at some point.
Good working parts as shown. Oil pressure gauge has been REMOVED. PARTS ONLY.
BRAND NEW old stock. Never mounted on a dash. No longer made. Rare find.
ONLY ONE SET AVAILABLE. Do not order more than one. These are NOT reproductions. These are original NOS fuses from. the 1960s.
Not working. No antenna mast. This is the actual part you will receive.
Wire harness as shown. Note this one is for the 300SD as it has the long wire going down to the oil pressure sending unit. BUPS
Used wiring set and cables as shown. These are the actual parts you will receive. The cover on the alternator plus is missing and the plug has been taped up. BUPS
The power window is stuck closed. Do the tests outlined in this video first. You may have to remove the regulator and to do that; you have to lower the window. But how???
Motor recently bench tested by Kent. The unit runs smoothly and gears are in good condition.
This is part 8 of Kent's 8-part video series on servicing and repairing the power sunroofs on the 1980 to 1985 W123, W126, and W201.
This is part 7 of Kent's 8-part video series on servicing and repairing the power sunroofs on the 1980 to 1985 W123, W126, and W201. This video will cover ONLY those issues related to the sunroof round motor drive assembly.
Did the engine just quit? Does it just not start even with prolonged cranking? What could it be? The first thing you want to determine with most older cars is whether there is spark to the plugs.
PLEASE NOTE: EACH HOLDER HAS SIX SLOTS
When removing valve covers or changing wires, replace these with new ones. They may look good, but they usually break due to engine heat and age.
These will no longer be printed when these are gone. They will still be available as a download. All books are signed by Kent. This is an end of an era for us. Most books are approximately 15 pages in length and covered with heavy clear plastic.
