Kohler 3.5CFZ, 4CZ, 5CFZ, 6.5CZ specs

13.Reconnect battery, negative lead last.

14.Start generator set and allow the set to run for about 20--30 seconds. Stop generator set and recheck coolant level by removing heat exchanger pressure cap. Add straight coolant, if necessary, until level is just below the overflow tube opening, then reinstall pressure cap. Repeat this step until coolant can no longer be added. This procedure should give an approximate mixture of 50% ethylene glycol and 50% water.

15.Wipe up spilled coolant and water with rags. Dispose of rags in a proper container.

16.Test run generator set for about five minutes and check for coolant leaks. This will allow the coolant mixture to mix completely. Stop generator set.

17.Rinse coolant flush kit hoses and fittings with clean water. Store kit for future use.

18.Dispose of used coolant in a proper manner. Do NOT pollute waterways!
