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.

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.

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.

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.

Engine and Radiator	2.5 gal (9.5 liters)
Reserve Tank	16 oz. (0.5 liters)

Operation in Freezing Weather

When operating in freezing weather, be certain the proper amount of antifreeze Table 8 has been added.
