Engine coolant
WARNING
Hot liquid under pressure!
Service when cool.
Failure to comply could result in death or serious injury.
W1187A
NOTICE: It is essential that a genuine approved pressure cap is used. If the cap is misplaced or damaged, obtain a
replacement from your Authorized NEW HOLLAND Dealer.
1. Open the radiator drain plug (1) and allow the coolant
to drain. (Drain cock is on the rear, left-hand side of
the radiator). Remove the radiator pressure cap to in-
crease the drainage rate.

2. After draining, flush the cooling system with clean water
through the radiator filler. When the flushing process is
complete, refill the cooling system with a 50/50 solu-
tion of ethylene glycol antifreeze and water through the
radiator until the coolant is
20 mm ( 0.79 in ) below the
neck of the radiator tank. Re-install the pressure cap.
NOTE: To avoid trapping air in the system, fill the radiator as slowly as possible thereby allowing any formation of air
pockets to disperse.
NOTE: The coolant level may drop as the coolant is pumped around the cooling system.
3. If the engine is not going to be operated immediately
following this coolant change, run the engine for one
hour to ensure that the water is distributed throughout
the cooling system. Allow the engine to cool and make
a final check to ensure that the water level is satisfac-
tory.
4. For cold climate (below freezing point), add a quality
anti-freeze solution. Add the solution to radiator in ad-
dition to water as follows:
