Coolant; Adding Coolant - Briggs & Stratton 470000 Operator's Manual

Coolant

• A 50/50 mixture is required of phosphate-free
antifreeze and tap water for heat dissipation, rust
resistance and lubrication.
• Normal reading on coolant temperature gauge (if
equipped) should be 175_ to 195_F (80_ to 90_C)
when engine is running.
• If coolant temperature rises above 220_ F (105_ C),
the temperature light (if equipped) will illuminate.
Idle engine down for a while. Then stop engine.
Once engine is cooled, check coolant level, fan belt
tension and clean any clogged radiator fins.

Adding Coolant

1. Fill radiator to bottom of filler neck and fill
reservoir between FULL and LOW
radiator cap.
Ê
2. Start and run engine for 30 seconds. See Starting
Instructions.
3. Shut engine off to allow it to cool. Recheck
coolant levels in radiator and reservoir.
Changing Coolant
Coolant should be replaced every year, unless an
approved extended life coolant is used. Then replace
every 3000 hours.

WARNING
•
Do not touch radiator or open radiator
cap, or open radiator reservoir when
engine is hot or running.
•
Allow engine to cool before changing
or adding coolant.
WARNING
Never remove 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 engine
coolant.
• Stop engine and allow to cool before
removing radiator or reservoir cap.
• To remove reservoir cap after engine is
cool, place a thick cloth over the cap
and remove it slowly.
• To remove radiator cap after engine is
cool, place a thick cloth over cap and
rotate it slowly counter-clockwise to the
first stop. Pressurized steam may emit
from the cap, stand back to avoid injury.
Once all pressure is released, rotate
cap counter-clockwise while pushing
down on cap to remove.
CAUTION
Used coolant is a hazardous waste product.
Dispose of used coolant properly. Do not
discard with household waste. Check with your
local authorities, service center, or dealer for
safe disposal/recycling facilities.
