Checking The Cooling System - Toro Reelmaster 3555 Operator's Manual

Note:
Toro Premium Engine oil is available from your
distributor in either 15W-40 or 10W-30 viscosity. Refer
to the parts catalog for part numbers.
Note:
The best time to check the engine oil is when
the engine is cool before it has been started for the
day. If it has already been run, allow the oil to drain
back down to the sump for at least 10 minutes before
checking. If the oil level is at or below the Add mark
on the dipstick, add oil to bring the oil level to the
Full mark. Do not overfill the engine. If the oil level
is between the Full and Add marks, no oil addition
is required.
1. Position the machine on a level surface.
2. Remove the dipstick
a clean rag.

3. Push the dipstick down into the dipstick tube and
make sure that it is seated fully. Pull the dipstick
out and check the oil level.
4. If the oil level is low, remove the oil-fill cap
(Figure 29) and gradually add small quantities of
oil, checking the level frequently, until the level
reaches the Full mark on the dipstick.

1. Radiator/oil cooler
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol antifreeze.
Check the coolant level at the beginning of each day
before starting the engine.
The capacity of the cooling system is approximately
5.7 L (6 US qt).
CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and
cause burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off

the engine, and remove the key from the ignition
switch.
2. Check the coolant level in the expansion tank
(Figure 31). With a cold engine, the coolant
level should be approximately midway between
the marks on the side of the tank.
