Coolant Solutions
Your tractor cooling system is equipped with an ethylene glycol coolant
solution that has a high boiling point.
IMPORTANT:
Change the coolant solution at the change interval
recommended in this manual (See Lubrication and service Chart). The
heat generated by the diesel engine causes a natural change in the
inhibitors in the coolant which results in loss of corrosion protection. The
loss of the inhibitors may cause water pump cavitation and cylinder block
erosion.
Install only ethylene glycol coolant solution in the cooling system. Use a
good quality, high boiling point, ethylene glycol that does not have any
additives to stop leaks. Do not install any rust inhibitors that are not
approved. It is possible that the rust inhibitors and ethylene glycol will not
mix and work against each other to decrease corrosion protection, form
deposits in the cooling system and cause damage to the cooling system
and the radiator.
Do not use a low boiling point, alcohol type coolant solution.
The boiling point of alcohol is below the tractor minimum operating tem-
perature, loss of coolant due to evaporation will result.
IMPORTANT:
Always have a minimum of 50 percent ethylene glycol
coolant in the cooling system at all times and at all ambient temperature
ranges. Do not install more than 50 percent ethylene glycol in the cooling
system unless the ambient air temperature will be less than – 37
°
C
( –34
°
F). More than 50 percent ethylene glycol decreases heat transfer
and will cause the engine surface temperature to be higher than normal.
