ENGINE COOLING SYSTEM
(Fig. 39–40)
1. Removing Debris—Remove debris from the rear screen,
oil cooler and radiator daily. Clean more frequently in
dirty conditions.
IMPORTANT: Never spray water onto a hot engine as
damage to the engine may occur.
A. Turn the engine off, release the hood latch and raise
the hood. Clean the engine area thoroughly of all
debris. Close the hood.
B. Unlatch and remove rear screen (Fig. 39). Clean
screen thoroughly.
C. Unscrew knobs and pivot the oil cooler rearward.
Clean both sides of the oil cooler and radiator area
thoroughly with compressed air. Do not use water.
Open the hood and blow debris out toward back of
the machine. Pivot the oil cooler back into position
and tighten knobs.
Note: Fan shroud may be easily unbolted from the
machine to simplify cleaning.
D. Install rear screen and secure the latches.
Note: Do not use water to clean the engine, as damage
may occur.
2. Maintaining the Cooling System—Capacity of the sys-
tem is 13.25 l. Always protect the cooling system with a
50/50 solution of water and Peugeot-recommended anti-
freeze (Part No. 93-7213). DO NOT USE WATER ONLY
IN THE COOLING SYSTEM.
A. After every 100 operating hours, inspect and tighten
hose connections. Replace any deteriorated hoses.
B. After every 2 years, drain and flush the cooling sys-
tem. Add anti-freeze (refer to Check The Cooling
System).
ENGINE FAN BELT (Fig. 41)
Check the condition and tension of fan belt after every 100
hours of operation (Fig. 49). Replace the belt as required.
1. Using a Universal Belt Tension Gauge (OTC model 1036,
1294 or Toro/Peugeot Digital Belt Tension Tool
(TOR4075), check the belt tension between the fan pulley
and the alternator pulley on the right-hand side of the
engine.
