Engine Coolant Specifications
Use a Long Life Coolant (LLC) or an Extended
Life Coolant (ELC) that meets or exceeds the
following guidelines and specifications.
Alternative Engine Coolant
If an Extended or Long Life Coolant is not
available, alternatively, you may use an ethylene
glycol or propylene glycol based conventional
coolant (green).
Notes:
1. ALWAYS use a mix of coolant and water.
NEVER use water only.
2. Mix coolant and water per the mixing
instructions on the coolant container.
3. Water quality is important to coolant
performance. Yanmar recommends that
soft, distilled, or demineralized water be
used to mix with coolants.
4. NEVER mix extended or long life coolants
and conventional (green) coolants.
5. NEVER mix different types and / or colors of
extended life coolants.
6. Replace the coolant every 1000 engine
hours or once a year.

Other engine coolants may affect
warranty coverage, cause an internal

the surrounding area before you
remove the cap.
