Engine Coolant Specifications
Use a Long Life Coolant (LLC) or an Extended Life
Coolant (ELC) that meets or exceeds the following
guidelines and specifications:
Additional Technical Coolant
Specifications:
• ASTM D6210, D4985 (US)
• JIS K-2234 (Japan)
• SAE J814C, J1941, J1034 or J2036 (International)
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:
• ALWAYS use a mix of coolant and water. NEVER use water
only.
• Mix the coolant and water per the mixing instructions on the
coolant container.
• Water quality is important to coolant performance. Yanmar
recommends that soft, distilled, or demineralized water be
used to mix with coolants.
• NEVER mix extended or long life coolants and conventional
(green) coolants.
• NEVER mix different types and / or colors of extended life
coolants.
• Replace the coolant every 1000 engine hours or once a year.
Filling Radiator with Engine Coolant
Fill the radiator and reserve tank as follows. This
procedure is for filling the radiator for the first time
or refilling it after it is flushed. Note that a typical
radiator is illustrated
