Of all the diesels Kent has owned the original glow system in his 1959 180D took the longest to heat up. It was just too annoying so he converted it to the fast glow system. Now instead of 30 to 45 seconds it only takes 5 to 10 seconds for the glow plugs to get hot enough to start the engine.
Problem & Solution
Common among these chassis:
Would you like to do that for your OM 636 or for any other old diesel for that matter (that has the old loop sytle glow plugs). Look at the difference between the old style and the newer pencil typle plugs.
On some of these old models it does require that you bypass the old resister and install a new one that can handle the higher voltage.
We have fast glow conversion kits for all the older diesels with series type glow plugs from the 1950's up to 1979. Just enter Fast Glow Conversion in the search box.
