I was just wondering if any of ya'll check your coolant additive? I check mine twice a year to make sure that it is a the correct level so I don't start getting cavitation in the engine block.

Thats great! All it takes to test it is to buy the fleetguard or baldwin test strips to test then add the additive from the dealer, if needed.

I dump coolant too often to warrant checking.

It's always gettin' fresh additive, and a filter to try and keep it clean...

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.

I check mine at every service.

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 don't put too much in, It get's new coolant with additive. Usually due to something breaking....

I just change my filter every now and then. When the coolant gauge quits working I know its time to change it...

Is there a Napa filter with the additive? I believe I am only running 4070 right now. Would there be any reaction with the gold coolant?

You can do several different things to prevent cavitation. Install a coolant filter or put in permenent type anti-freeze like texaco's red. In all of the Diesel shops I have worked in, the coolant got checked at every service, but once you get in the habit of doing it you will find out how often you will have to adjust it, by adding liquid or changing the filter.
The cavitation problem is something that is more of a problem with wet sleeve engines because the air bubbles that cause cavitation stick to a machined surface more so than a cast surface witch all 7.3, 6.0, 5.9 etc. etc. engines have. But it can still eat through it.
Cavitation itself is caused by air bubbles imploding into the liner, or cylinder wall, due to harmonics created by the cylinder firing during the combustion process. As the cylinder fires it rings the liner, or cylinder like a bell and as that happens the air bubbles implod into the liner and over time it will go all the way through it. I've seen cavitation go through a big bore cummins engine in less than 1 year and with only 90,000 miles on it.
Caterpillar has some very informative information on the subject just call up any Caterpillar dealer and ask the parts or service dept. for any information on cavitation.
Good luck!

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?

Your best bet is get the test kit and check your coolant. Don't just assume it needs it. Too much is just as bad as too little. If your interested in learning more about cavitation google caterpillar cavitation, there is several service letters about the subject.

Just remember that mileage is for trucks it should say something on the jug about time also. I think it's like 3-5 years and you may have to add an additive package to it. I have the Texaco extended in mine and I think it's 5 years and then you should add the additive package. You might check into it. In fact I think the Cat stuff is made by Texaco, not sure. But it's defiently good stuff.
