Perkins 4-108 Cooling System

External Since: Nov 07, 2007 Posts: 1

I have to drain and replace the antifreeze coolant in my Perkins 4-108
marine engine. My problem is I can't find the drain valve for the
antifreeze. Can anyone tell me where it is located on the engine? I
thought it was on the port side over the starter but I can't find it
there.
Thanks,
Farny

My 4-108 has the drain on the starboard side under the fuel filter,
but the starter is on the port side. If you use starboard and port
there is not confusion....unless someone has an engine installed with
a "V" drive....
