Check Engine Coolant Level; Change Engine Coolant - Ferris IS2000Z Diesel Operator's Manual

CHECK ENGINE COOLANT LEVEL

The engine coolant level and quality should be
checked before each use, when the engine is cool
and off.
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. Remove the engine access panel (See Figure 23).
2. Check the coolant level only at the overflow
reservoir (A, Figure 28). The coolant level should
be at the LOW (COLD) mark.
3. If the coolant level is insufficient, remove the cap
(E) from the reservoir and add coolant to the "H"
mark.
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

This procedure is for refilling the radiator for the first
time or refilling it after it is flushed.
1. Check to be sure that all hoses are connected and
all clamps are in place.
2. Turn the radiator cap (A, Figure 29) counter-
clockwise 90 degrees. Push down on the cap and
continue to turn counterclockwise to remove.
NOTE: Do NOT attempt to remove the radiator cap
without pushing down on it first.
3. Pour the engine coolant slowly into the radiator
until it is even with the lip of the engine coolant
filler port. Make sure that air bubbles do not
develop as you fill the radiator. As the coolant
enters the radiator, squeeze the radiator hoses (B,
Figure 28) to help remove air from the cooling
system.
4. Fasten the radiator cap. Align the tabs on the back
side of the radiator cap with the notches on the
engine coolant filler port. Press down and turn the
cap clockwise about 90 degrees.
5. Remove the cap of the reserve tank and fill it to
the LOW (COLD) (C) mark with engine coolant.
Reinstall the cap.
6. Check the hose the connects the reserve tank to
the radiator (B, Figure 29). Be sure it is securely
connected and there are no cracks or damage. If
the hose is damaged, engine coolant will leak out
instead of going into the reserve tank.
Regular Maintenance
WARNING
PRESSURIZED SYSTEM
Hot coolant can cause serious burns. Never
open the radiator cap. Wait until the engine is
cool before checking the coolant level or
removing the reservoir cap.
