Put some water in and test.On my mishimoto radiator which way is closed on the drain cock, in or out???
Coolant overflow bottle.The radiator cap has that little do-flanger on it, what do i connect it too??
Dexcool is fine. You need distilled water. Honda coolant is recommended.Is the havoline Dexcool ok to use in the mishimoto radiator. Also is tap water ok or do i need filtered or distilled??
Take the volume between the oem cooler and the one you have and modify your fill by the difference. You'll have to do this research on your own.I added a tranny cooler to replace the one in the oem radiator, how much more trans fluid should i add??
