Listed In Categories
If you own an early 5 cylinder non-turbo diesel then this is a must have diesel engine kit! This glow plug upgrade will do three things that will put a smile on your face: 1. Your engine will start faster and cold idle smoother. 2. Your glow plugs will last longer. 3. If you should burn out one or two glow plugs your engine (if healthy) will still start! If you have ever been stranded with bad glow plugs before you know the frustration. This kit will allow you to throw away your old series style glow plugs forever and replace them with the more efficient pencil style parallel glow plugs used in the newer diesels. ONLY FITS THE FOLLOWING: 115 and 123 chassis 5 cylinder non-turbo 300D Diesel engines from 1975 to 1979.
The complete kit includes the following:
- 5 Monark German made Fast glow plugs ( large thread type)
- 4 special wire connectors
- complete bound installation instructions
No specialty tools are required. Once completed you will immediately notice improvement in your start times. Could starts can be done with only 8 to 12 seconds of glow time and hot starts with 2 to 3 seconds. You will love this upgrade!
IMPORTANT NOTE FOR 1975-76 115 OWNERS: The included instruction book is written specifically for the 123 300D and the pictures are from the same chassis. The general principles of installation are the same for the 115 chassis. The major difference would be the pictures and reference made concerning the fuse on the firewall. This information will NOT apply for you. The 115 does not have that fuse arrangement. Operation on both chassis is the same.
It is important to understand you will lose a correct functioning glow light when you install these new plugs. You will have to use a mental count to determine low long you have your key turned to the glow position. Once completed you will immediately notice improvement in your start times. Could starts can be done with only 8 to 12 seconds of glow time and hot starts with 2 to 3 seconds. You will love this upgrade!
SVO WVO: This is a must have if you plan to run straight vegetable oil fuel.
If your factory relay is acting up or not working properly then this kit will not work. I recommend you purchase our complete kit that has a manual push button control. You can opt for the kit shown below that bypasses your factory relay and gives you "push button" manual control.
Mercedes Early 300D 300CD 300TD Non-Turbo Glow Relay Manual Override Kit w/ Upgrade Plugs

If you are tired of glow plug problems, then this kit is made for you. How would you like to start your old diesel in 10 to 15 seconds? How would you like to be able to still start your car with one or two glow plugs burned out? How would you like to be able to control when and how long your glow plugs stay on? Maybe you have had the experience of glow-cycling your engine two or three times on those cold winter mornings or worse yet, maybe you have had the misfortune of having your glow relay staying on and not shutting off.
