Dispose of used engine coolant or recycle. Various
methods have been proposed to reclaim used cool-
ant for reuse in engine cooling systems. The full distil-
lation procedure is the only method acceptable by
Perkins to reclaim the coolant.
For information regarding the disposal and the
recycling of used coolant, consult your Perkins
distributor.
