Figure 7.7 – High Fill Tank
Check coolant level daily. The level in the high fill tank should be
maintained at the “MIN” mark (1, Figure 7.7) when the engine is
cold.
NOTICE
• Failure to maintain the coolant at the proper level can cause
engine damage. Your warranty will not cover engine damage
due to overheating or any other cause associated with improper
coolant levels.
• Use only Indmar propylene glycol coolant. Use of any other
coolant or mixing coolant types can cause engine damage.
Damage to your engine from use of any other type of coolant is
not covered by warranty.
• The coolant system should be flushed and coolant replaced
every two years. This should be performed by a qualified Indmar
service technician.
When adding coolant, add only a 50/50 mix of propylene glycol
coolant and distilled water in accordance with the directions on the
container
. Do not overfill the tank. Do not mix anti-freeze types. Do
not use concentrations that exceed manufacturer’s specifications.
If the cooling system is completely empty, see your Indmar dealer
for assistance immediately to purge system. Purging the system is
a difficult procedure that is not recommended for the boat owner.
