Maintenance
Servicing the Cooling
System
Service Interval: Every 100 hours—Check the
cooling-system hoses for wear and
damage.
Every 400 hours/Yearly (whichever comes
first)—Check the coolant (as directed by the
manufacturer) and change if necessary.
Cooling system capacity: 5.5 L (5.8 US qt)
Coolant type: a solution of 50% water and 50%
permanent ethylene-glycol antifreeze
Important:
Do not add coolant to an overheated
engine until the engine has fully cooled. Adding
coolant to an overheated engine may crack the
engine block.
Check the engine-coolant concentration as directed
by the coolant manufacturer.
Checking the Coolant Level
Service Interval: Before each use or daily
CAUTION
If the engine has been running, the coolant
may be hot and pressurized. If you open
the radiator cap when the coolant is hot, it
could spray out and severely burn you or
bystanders.
Allow the engine to cool for at least 15
minutes before opening the radiator cap.
1. Position the sprayer on a level surface.
2. Set the parking brake, stop the pump, shut off
the engine, and remove the key from the starter
switch.
3. Carefully remove the radiator cap and the
expansion-tank cap (Figure 85).
