1) Remove radiator cap when engine is cool.
a) Turn cap counterclockwise slowly until it reaches
a “stop”. (Do not press down while turning it).
b) Wait until pressure is relieved (indicated by a
hissing sound) then press down on cap and
continue to turn it counterclockwise.
WARNING
!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot.
Scalding fluid and steam can be blown out
under pressure if cap is taken off too soon.
2) With radiator cap removed, run engine until upper
radiator hose is hot (this shows that thermostat is
open and coolant is flowing through system).
3) Stop engine and drain coolant.
4) Close drain plug. Add water until system is filled and
run engine until upper radiator hose is hot again.
5) Repeat Steps 3) and 4) several times until drained
liquid is nearly colorless.
6) Drain system and then close radiator drain plug (1)
tightly.
7) Remove reservoir tank (1) and remove cap (2) from
reservoir tank and pour out any fluid, scrub and
clean inside of tank with soap and water.
Flush it well with clean water and drain. Reinstall
tank.
8) Add coolant that is a mixture of good quality ethylene
glycol antifreeze and water to radiator and reservoir
tank. For coolant concentration, refer to “Coolant
Level Check”. Fill radiator to the bottom of filler neck
and reservoir tank to FULL level mark (3).
9) Reinstall reservoir tank cap and align match marks
(4) on reservoir tank and its tank cap.
10) Run engine with radiator cap removed, until radiator
inlet hose is hot.
11) With engine idling, add coolant to radiator until level
reaches the bottom of filler neck. Install radiator cap,
making sure that the ear of cap lines is parallel to
radiator.
