Check Engine Coolant; Change Engine Coolant; Clean Radiator & Screens - Ferris F800X Series Operator's Manual

Operation
Check Engine Coolant Level
The engine coolant level and quality should be checked
before each use, when the engine is cool and off.
WARNING
If engine is warm, DO NOT remove radiator
cap.
Escaping steam can cause burns.
Never remove the radiator cap or radiator
reservoir cap while the engine is hot or
running. Severe thermal burns or injury can
occur by escaping steam or hot coolant.
• Do NOT touch hot radiator or open reservoir when
engine is running.
• Stop and allow engine to cool before removing the
radiator cap or the reservoir cap and before changing or
adding coolant.
The cooling system is a closed type. Never open the
radiator cap unless you are flushing the system. Opening
the radiator cap may induce air into the cooling system and
may cause overheating.
1. Open the hood to gain access to the overflow bottle. See
Figure 6.
2. Check the coolant level only at the overflow reservoir
(A, Figure 6). The coolant level should be at the LOW
(COLD) mark (B).
3. If the coolant level is insufficient, remove the cap (D)
from the reservoir and add coolant to the LOW (COLD)
mark. See engine owners manual for specific engine
coolant specifications.
4. Reinstall the cap.
NOTE: Proper coolant mix is a 50/50 mixture of ethylene
glycol and distilled water. See engine owners manual for
engine coolant specifications.

Change Engine Coolant

See engine owners manual for specific engine coolant
procedures. The drain valve is located at the base of the
right-hand side of the radiator.
Clean Radiator & Screen
Clean the radiator (E) and radiator screen (F)
use, or as required (depending on conditions) to allow
proper air-flow through radiator and hydraulic oil cooler.
1. Raise the seat plate.
2. Lift the radiator screen straight up to remove the screen.
Flush the screen with water or blow clean with air. Flush
the radiator core with water or blow clean with air. See
engine owners manual for proper radiator cleaning
procedures.
