15. Loosen the water pump air bleed bolt,without removing it, to allow all of the air
to escape from the air bleed bolt hole. 16. When coolant begins to flow out of the
bolt hole, tighten the water pump air
bleed bolt to the specified torque.
17. Loosen the cylinder head air bleed bolt, without removing it, to allow all of the air
to escape from the air bleed bolt hole.Antifreeze/water mixture ratio:1:1
Recommended antifreeze: High-quality ethylene glycol antifreeze con-
taining corrosion inhibitors for aluminum
engines
Coolant quantity: Radiator (including all routes):3.24 L (3.42 US qt, 2.85 Imp.qt)

18. When coolant begins to flow out of thebolt hole, tighten the cylinder head air
bleed bolt to the specified torque.
19. Start the engine and let it idle for ten mi- nutes.
20. Rev the engine five times.
21. Pour additional coolant into the radiator until it is full. 22. Stop the engine and allow it to cool. If the
coolant level has dropped after the en-
gine has cooled, add sufficient coolant
until it reaches the top of the radiator, and
then install the radiator cap.
23. Check the coolant level in the reservoir. If necessary, remove the coolant reservoir
cap, add coolant to the maximum level
mark, and then install the cap.
24. Start the engine, and then check for cool- ant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 25. Install the panel and the hood.EBU32400Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.

Installation1. Clean the surface of the spark plug gas-
ket and its mating surface, and then wipe
off any grime from the spark plug
threads.
2. Install the spark plug and tighten it to the specified torque. If a torque wrench is not
available when you are installing the
spark plug, a good estimate of the cor-
rect torque is one-quarter to one-half turn
past finger tight. Have the spark plug
tightened to the specified torque as soon
as possible.
3. Install the spark plug cap.
4. Lower the cargo bed.
EBU34821Cleaning the air filter elementThe air filter element should be cleaned every
20–40 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter elem ent rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.NOTICEECB02270Never operate the engine with the air filter
element removed. Doing so would allow
unfiltered air to enter, causing rapid en-
gine wear and possible engine damage.
Additionally, the fuel injection system
would be affected, re sulting in poor engine
performance and possible overheating.
Spark plug gap: 0.8–0.9 mm (0.031–0.035 in)
Tightening torque: Spark plug:13 Nm (1.3 m·kgf, 9.4 ft·lbf)

19. Install the seat by installing the bolts, and
then tighten the bolts to the specified
torque.
20. Place the rubber damper in the original position, and then install the rear center
passenger seat cushion.
EBU32430Cleaning the air filter case/duct check
hoseThere is a check hose at the bottom of the air
filter case under the cargo bed and a check
hose at the bottom of the air duct. The air
duct check hose can be accessed under the
vehicle. If dust or water collects in a check
hose, empty the hose and clean the air filter
element and air filter case.

2. Remove the tailpipe by pulling it out ofthe muffler, and then remove the gasket.
3. Tap the tailpipe lightly, and then use a
wire brush to remove any carbon depos-
its from the spark arrester portion of the
tailpipe and inside of the tailpipe housing. 4. Install the gasket, and then insert the tail-
pipe into the muffler and align the bolt
holes.
5. Install the bolts and tighten them to the
specified torque.1. Tailpipe bolt

EBU32630Wheel installation1. Install the wheel and the nuts.TIPTapered nuts are used for both the front and
rear wheels. Install the nuts with their tapered
side towards the wheel. 2. Lower the vehicle so that the wheel is onthe ground.
3. Tighten the wheel nuts in a crisscross
pattern to the specified torque.
WARNING
EWB03400Do not reverse the rims on your Yamaha
Viking VI to widen the track width. Install-
ing wheels improperly increases the risk of
wheel failure and accidents. EBU32640BatteryThe battery is located under the hood. (See
page 8-10 for hood removal and installation
procedures.)
This model is equipped with a VRLA (Valve
Regulated Lead Acid) battery. There is no
need to check the electrolyte or to add dis-
tilled water. However, the battery lead con-
nections need to be checked and, if
necessary, tightened.

2. Remove the tail/brake light bulb holder(together with the bulb) by turning it
counterclockwise.
3. Push the burnt-out bulb in and turn it counterclockwise to remove it from the
bulb holder.
4. Push a new bulb in and turn it clockwise to install in the bulb holder.
5. Install the bulb holder (together with the
bulb) by turning it clockwise.
6. Install the panel. 7. Install the quick fastener screws, bolts,
and nuts, and then tighten the panel nuts
and the panel rear bolt to the specified
torques.
EBU32700TroubleshootingAlthough Yamaha vehicles receive an inspec-
tion before shipment from the factory, trouble
may occur during operation. Any problem in
the fuel, compression, or ignition systems can
cause poor starting and loss of power. The
troubleshooting chart describes a quick, easy
procedure for making checks. If your vehicle
requires any repair, take it to a Yamaha deal-
er.
