pressure cap and opening all water system petcocks.
2. Remove zinc rod (usually located in heat exchanger) and see if it
needs replacing. The zinc rod will take care of any electrolysis that
may occur between dissimilar metals. Insert new zinc if necessary.
3. Fill fresh water cooling system with antifreeze of a reputable
make. (Refer to Cold Weather Precautions.)
4. Start engine. When temperature gauge indicates l7S·F, shut engine
down and drain lubricating oil. Remove and replace filter. Fill sump

7. Remove injectors and spray oil into cylinders.
8. Replace injectors with new sealing washer under each injector.
Turn engine slowly over compression.
9. Top off fuel tank completely so that no air space remains, thereby
preventing water formation by condensation.
10. Leave fuel system full of fuel.
11. Change fuel filters before putting the engine back in service.
