diesel engines have a nasty habit of wearing small holes into the cylinder bores starting from the coolant side of the liner and working its way in towards the piston, this is called by "cavitation" some engines are worse than others. I have been told a couple of different things on what actually causes the cavitation. One theory was that it is caused by an electric spark that is created by the piston moving up and down. the other theory I have heard is that it is caused by air bubbles that form in the coolant that are created through vibrations from the movement of the piston. weather either one of those theories is right I'm not sure, but the main point is that the coolant additive helps stop this cavitation.Ol Red said:Can someone explain this additive in more detail for me. I have not been told anything about it before. My 03 F-450 is the first desiel I have owned. Trying to take proper care of it. I'm learning alot on this sight. - Thanks, Ol Red
Becarefull not to put too much aditive in. if you get to much in there the additive can settle out in a powder form and stop up hoses and passages in your engine.Fast_Ashley said:I dump coolant too often to warrant checking.
It's always gettin' fresh additive, and a filter to try and keep it clean...
I don't put too much in, It get's new coolant with additive. Usually due to something breaking....pontiacross said:Becarefull not to put too much aditive in. if you get to much in there the additive can settle out in a powder form and stop up hoses and passages in your engine.
i have run the napa kool for 10 years its as good as any otherStraight Flush said:I just flushed my coolant..because I replaced the waterpump, and added Zerex original green coolant. I went to NAPA and bought two pints of NAPA Kool, but decided not to add that and went to the Ford Dealership and got the Motocraft SCA stuff...I thought that would be safer. Any comments?
