Changing engine coolant

[Klink10]

Distilled water as that is what it is dilluted with in the first place. Bear in mind that depending on your location the dilluting further may weaken the temp range so check you have the right mix for your weather conditions. Follow the guidelines in the manual on refilling and be sure to burp the system. I drained the block, overflow tank and radiator plus took out the water pump as there is a cavity behind it that will still hold coolant even after all that I did.
