The coolant is
amixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R corrosion protection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the cool-
ant during operatio nisa pproximately 266 ‡
(13 0† ).
Th ea ntifreeze/corrosion inhibito rconcentra-

R be at leas t50% .Thisw illp rotect the engine

R no te xceed 55% (antifreeze protection
down to -49‡[-45† ]).O therwise, heat
