Changes for 2005 NEW FLUSH FITTING FOR ALL ENGINES New antifreeze for 05
O-Ring
This is the new flush fitting. It has a positive O-ring seal in addition to the conventional hose seal. The O-ring should periodically be lubricated with a drop or two of engine oil. The older blue flush fitting can be upfitted with this new style, o-ring sealed, flush fitting; however both halves of the new fitting have to be used together. The half that connects to the engine hose has a relief cut in it for the o-ring. If just the cap is changed, the o-ring will be cut by the old lower fitting. CAUTION: Care should be used with the old blue fitting. If it isn’t tight, it can cause an air leak to the inlet side of the raw water pump causing an overheat situation and damage to the pump impeller. Starting with engine serial number 4012133180, all closed cooling system engines shipped from Lexington with have Ethylene Glycol antifreeze installed.
