CAUTION: Explosive release of fluids from
pressurized cooling system can cause serious
burns.
Shut off engine. Only remove filler cap when
cool enough to touch with bare hands. Slowly
loosen cap to first stop to relieve pressure
before removing completely.
IMPORTANT: Never pour cold liquid into a hot
engine, as it may crack cylinder head or
block. DO NOT operate engine without
coolant for even a few minutes.
John Deere TY15161 Cooling System
Sealer may be added to the radiator to
stop leaks. DO NOT use any other
stop-leak additives in the cooling
system.
Air must be expelled from cooling
system when coolant is added.
Coolant level should be maintained to the bottom of the
radiator filler neck (A). If needed, as coolant as follows.
1. Loosen temperature sending unit fitting at rear of
cylinder head or plug in side of thermostat housing to
allow air to escape when filling system.
IMPORTANT: When adding coolant to the system, use
the appropriate coolant solution. ( See
ENGINE COOLANT SPECIFICATIONS in
Fuels, Lubricants, and Coolant Section
for mixing of coolant ingredients before
adding to cooling system.)
Do not overfill cooling system. A
pressurized system needs space for
heat expansion without overflowing at
top of radiator.
2. Fill radiator (B) until coolant level touches bottom of
radiator filler neck (A).
