Engine Cooling System - Toro 30582 Operator's Manual

• Clamp off the hose on each side of the fuel filter to
prevent gas from pouring out of the hoses when you
remove the filter.
• Place a drain pan under the filter.
• Loosen the screw and nut securing the fuel filter
mounting clamp to the mounting plate (Fig. 41).
• Loosen the hose clamps and slide them away from
the filter (Fig. 41).
• Remove the filter from the fuel lines.
• Install a new filter and move the hose clamps close
to the filter. Make sure flow direction arrow points
toward the engine.
4. If the fuel system becomes contaminated or if machine
is to be stored for an extended period, drain fuel tank by
pumping fuel out the top of the tank. Clean tank and
flush it with clean fuel.
Important Following the maintenance steps listed
above will, under normal conditions, keep the system
trouble-free. However, if the indicator light on the control
panel and audible warning signal activate during operation,
the engine should be stopped and the fuel system serviced
before operation is resumed. This can prevent serious
engine damage from occurring.

Engine Cooling System

The cooling system holds approximately 3.9 gal (14.7 l) of
a 50/50 solution of ethylene glycol anti–freeze and water.
To properly maintain the system, use the following
procedures:
1. Check coolant level each day before starting the engine;
refer to Check Cooling System in Before Operating
section.
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.
2. Each day after operation, clean debris from the radiator
grille. Clean more frequently in dusty and dirty
conditions.
A. Move seat forward as far as possible.
B. Remove upper and lower grille assemblies (Fig. 42).
