Question for Dave S
Here's my reponse to "cavitation???" Hopefully you or anyone else can help me out-
What's the best / appropriate way to do a coolant flush and change? When you say flush the system out a couple times are you talking with water, cleaner, or new coolant? On the ShopDiesel site they sell Fleetguard® Heavy Duty Cooling System Cleaner/Restore at a price of $25.33 per gallon. Not only is that expensive, but they don't say how much you have to use or clearly how you go about using it (if you read the link for the product you'll see why I say "clearly). I plan on starting from scratch with the truck I just bought because I don't know how the previous owner maintenanced it or how much he knew as far as cavitation goes. Thanks

I would use a good flushing agent and lots of water afterwards.
That Fleet guard stuff is probably great stuff, I have never used it though.
I am sure, kinda, that there will be detter directions on the bottle.
If it cleans all the garbage out of the radiator and block as well as the heater coil and oil cooler, 25 dollars is cheap.
My motor is new so I never needed to flush it out till now with the green/ non green antifreeze/SCA debate. I am concerned enough after reading the product info the other night, that if the Ford Dealer here has the Fleetmaster flush, I will buy it and use it.
Nothing that they make is to good for my truck, I run 25 dollar a gallon Delvac 1 synthetic oil in it as well with a 15 dollar Fleetguard filter.
I am going to change the antifreeze to VC7A and DCA4 just for piece of mind as soon as I get it flushed out good.
