where can u get them? napa never heard of them, nor had oreillys

 

Napa carries it, it's called NapaKool. If they don't have any in store, they should be able to get it within a day I would think.

 

they do have napakool, she said that wasnt it. but she also doesnt know anything other than what the computer said about it

 

Did she even know what SCA stood for. You'd be surprised at how many parts counter people would give you the deer in the headlight look and say huh.

 

I buy mine from B-Line truck lube shop, its only 3 bucks to treat 5 gallons.

 

she asked me what it was... no where here in podunk has stuff like that. i talked to an uncle today who is a mechanic and he had neer heard of it either... in an area full of old diesels i know of 1 who actually treats his truck. and he's offshore, cant find out where he gets his.

 

I like the free barbeque at b-line.

 

I'd rather deal with them than have them try to baffle me with B.S.

What'd really be nice is if car/truck owners would support the parts stores who have knowledgeable counter staff so they could afford to keep them in their employ.
Where I live all of the really knowledgable guys either quit or retired 5-10 years ago, so now I just find out what's right myself and go tell the pimple-faced counter people how to get what I need. It's a sad state of affairs.

 

Tell your uncle it's like Nalcool, if he's been around trucks, he should know that name. Napacool is napa's version.

 

Try a ford dealership, I got some there for $7 a bottle.

 

We use DCA 4 at work.

 

i got some kinda purple looking additive from o rieley i asked for sca's for 7.3, 6.9 diesel and they gave me that, so i guess it works

 

Sounds like the right stuff.

 

yea they said it was, i kinda think that my dads 7.3 may be on the edge of cavitating, we have owned it for a few years, but the people before us had it since it was new, well after i flushed the coolant out of that thing i swear it was what come in it from the factory it was the rustiest stuff i have ever saw, and i bet i wasted 100 gallon of water flushing that thing, and one time about a year ago i went and cranked it, well it turned over one time and it locked up like it was hydrolock, well i kept playing with it and it turned over finally made a kinda knocking sound alittle bit missed a little and never done it again so idk, but i bought me a 6.9 now, and there no telling when his will lay down

 

Is it loosing coolant.

Deopending on where the hole in the cylinder is, the coolant may be on top of the piston or go straight into the oil pan.
The engine will only hydrolock when coolant is on top of the piston.
And if you just bump the starter or if the engine sits long enough the coolant will leak down to the oil pan and the engine will run normally.

If the cavitation hole is low in the cylinder you may not even see compression in the radiator.
