Cooling System Flush and Refill
1. Remove radiator cap when engine is cool:Turn cap counterclockwise slowly 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 counterclockwise.
WARNING: To help avoid danger of being burned, do not remove radiator cap while engine and 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 open radiator drain plug to 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 tightly.
7. Disconnect reservoir tank hose from radiator. Remove 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 and hose.
8. Add 50/50 mixture of GOLDEN CRUISER 1200 (Good quality ethylene glycol anti-freeze) and water to radiator and tank.
Fill radiator to the base of radiator filler neck and reservoir tank to "FULL" level mark. Reinstall reservoir tank cap.
NOTE:
^ Be sure to check cap gasket is located as shown figure and breather hole is not plugged.
^ When installing reservoir tank cap, turn cap pipe forward.
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 tank hose.
