Engine Coolant Specifications; Filling Radiator With Engine Coolant - Yanmar 2V Series Operation Manual

CAUTION
• Only use the engine coolant specified.
Other engine coolants may affect
warranty coverage, cause an internal
buildup of rust and scale and / or
shorten engine life.
• Prevent dirt and debris from
contaminating the engine coolant.
Carefully clean the radiator cap and
the surrounding area before you
remove the cap.
• NEVER mix different types of engine
coolants. This may adversely affect the
properties of the engine coolant.

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,
