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!
Cosmetic replacement. Very nice looking cigarette light, but I have not tested so can not confirm if it works or not. I may work fine but can not guarantee. Priced accordingly. Not returnable.
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.
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.
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.

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?

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.
Often rotten and torn. Replace with new when working on your fuel delivery system. PLEASE NOTE: These are included when you purchase any of our fuel pump delivery kits.

In this 29-minute instructional video, Kent will show you how to convert your old points ignition to an efficient modern electronic ignition. Rid yourself of those old high-maintenance distributor points forever.
Kent worked on this conversion for over 5 years trying ot find the right components to correctly and reliably fit the V8 distributor. Success finally came when he decided to make a custom shutter for the optical trigger.
In this 10 minute instructional video Kent will explain why you want to "jump" your K-jet fuel pump relay, how to do it, how to find the location in you car, and why he prefers to have a long "switchable" jumper.
Someone is going to need this so I saved it. All the wiring behind the instrument cluster. You may need this for reference or to replace burned or damaged wires. Includes 5 bulb holders as shown. For 1978 to 1980 300SD only.
This is a high-quality ACM aftermarket part. The fan runs smooth and air movement is very strong.
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.
