DRAIN & REFILL

1. Draining the cooling system is always done with the engine COLD.
2. Remove the reservoir tank cap.
3. Position the drain pan under the draincock on the bottom of the radiator. Additionally, some engines have a draincock on the side of the engine block, near the oil filter. This should be opened to aid in draining the cooling system completely. If for some reason the radiator draincock can't be used, you can loosen and remove the lower radiator hose at its joint to the radiator.

   CAUTION
   When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

4. When the system stops draining, close both draincocks as necessary.
5. Using a funnel if necessary, fill the reservoir tank with a 50/50 solution of antifreeze and water. Allow time for the fluid to run through the hoses and into the engine.
6. Start the engine and let it idle about 10 minuets; add the coolant/water mixture up to the FULL level.
7. Tighten the cap.
8. Race the engine 2000–3000 rpms for about 5 minutes, then stop the engine.
9. After the coolant drops, remove the cap and add coolant to the FULL level again.

10. Securely tighten the cap again, then start the engine and check the level.
