CHECK ENGINE COOLANT LEVEL

The engine coolant level and quality should be checked before each use, when the engine is cool and off.

1.Remove the radiator pressure cap (A, Figure 18) to check the fluid level.

2.Coolant level should be 1/2” (13mm) below the bottom of the filler tube. If coolant level is low, add coolant until level is 1/2” (13mm) below the bottom of the filler tube. Proper coolant mix is a 50/50 mixture of ethylene glycol and distilled water. See engine owners manual for engine coolant specifications.

3.Check the coolant level in the radiator expansion tank (Figure 19). If coolant level is low, remove the cap add coolant until level is at the “FULL” line. Proper coolant mix is a 50/50 mixture of ethylene glycol and distilled water. See engine owners manual for engine coolant specifications.
