6B-14 ENGINE COOLING
Cooling System Flush and Refill
1) Remove radiator cap when engine is cool.
Turn cap slowly to the left until it reaches a “stop” (Do not
press down while turning it).
Wait until pressure is relieved (indicated by a hissing sound)
then press down on cap and continue to turn it to the left.
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 open radiator drain plug to drain coolant.
4) Close drain plug (1). 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 cooling system and then close radiator drain plug
tightly.
7) Disconnect hose from reservoir (1). Remove reservoir and
pour out any fluid. Scrub and clean inside of reservoir with
soap and water. Flush it well with clean water and drain.
Reinstall reservoir and hose.
8) Add 50/50 mixture of good quality ethylene glycol antifreeze
and water to radiator and tank.
Fill radiator to the base of radiator filler neck and reservoir to
“FULL” level mark (2). Reinstall reservoir cap, aligning the
arrow marks (4) on the reservoir and cap.
9) Run engine, with radiator cap removed, until radiator upper
hose is hot.
10) 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 up with reservoir hose.
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 pres-
sure if cap is taken off too soon.
