Subject: Re: Coolant systems (clean and properly maintained) by Durango_Boy on 2009/7/8 1:01:16 If I'm flushing an engine in a car that's very dirty and has a lot of crap and sediment I will use this procedure. First I disconnect the radiator vie the upper and lower hoses and drain the engine completely using the side plugs and a little water to flush the coolant out. I will use a dummy lower hose, tied u, and above the top of the engine level. Disconnect and tie up the heater hoses so they are above the top of the engine level. Then I will fill the engine block with plain white vinegar. Fill it till it pukes out the water neck...the whole engine should be full of vinegar. This will eat at any scaling that's on the inside walls of the block and it'll loosen most of the rust sediment layers. After two days I will drain and flush with watch...back flushing is also a very helpful tool so the flushing water is flowing opposite of the normal coolant flow. Back flush the radiator, then reconnect all the hoses, replacing any old and worn hoses if needed. Fill with preferred mixture of distilled water and coolant, and in hot areas...a bottle of Wetter. I use a mixture of 75% water, 24% coolant, and TWO bottles of Wetter. |
