Maintenance
Radiator/Cooling System
COOLaNT (aNTIFReeze/SummeR COOLaNT/
WaTeR)
yaNmaR recommends antifreeze/summer coolant for use in
their engines, which can be purchased in concentrate (and
mixed with 50% demineralized water) or pre-diluted. See the
yanmar engine Owner’s manual for further details.
Day-to-day addition of coolant is done from the recovery
tank. When adding coolant to the radiator, DO NOT remove
the radiator cap until the unit has completely cooled. See
Table 7 for engine, radiator, and recovery tank coolant
capacities. Make sure the coolant level in the recovery tank
is always between the “H” and the “L” markings.
Operation in Freezing Weather
When operating in freezing weather, be certain the proper
amount of antifreeze Table 8 has been added.
WaRNINg
If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator cap
until the unit has completely cooled. The
possibility of hot! coolant exists which can
cause severe burns.

When the antifreeze is mixed with water, the antifreeze
mixing ratio must be less than 50%.
3. Remove the drain plug to drain the oil.
4. After oil is sufficiently drained, securely tighten the
drain plug.
5. Using a filter wrench, turn the oil filter counter-clockwise
to remove.
6. Clean sealing surface on engine where filter mounts.
7. Coat the seal of the new oil filter with clean engine oil.
Install new filter first by hand until it contacts the engine
sealing surface. Tighten it another 3/4 turn using the
filter wrench.
8. Fill engine crankcase with high quality detergent oil
classified "For Service CF, or CF-4". Fill to the upper
limit of dipstick. DO NOT overfill. Crankcase oil capacity
with oil filter replacement is 3.5 qts. (3.3 liters).
9. Run the engine briefly for several minutes. Watch for
oil leakage. Shut the engine down and allow it to sit
for several minutes. Top off the oil to the upper limit on
the dipstick.
10. Be sure to coat the seal (Figure 23) of the new oil filter
with clean engine oil.
