Anybody using this stuff as your DCA?

NAPA Kool

Will it work for our PSD's? I drained the coolant and re-filled with regular green Prestone and distilled water. Now I want to add the SCA and be finished for a while with the cooling system, I just don't want to add the wrong stuff...

 

That's what I've been using for years

 

I figured it's tough to go wrong with anything from NAPA, but I want to get this right before I add it to 4+ gallons of new antifreeze!

 

I've been running it for some time now as well

 

And it tests okay on the WIX test strips?

 

Yes it does.

 

Anybody else before I go dump it in?

 

i have been using it in my 88 for 23 years, and in the 02 since i got it 4 years ago.

 

Well I guess that pretty well settles it for me. I'm gonna dump in about 2 pints and run it a couple days then test it again. Bought a 4 pint jug for $22 at the local NAPA on the way home tonight.

 

Dang I have a napa warehouse about 2 miles from my house and they Sell the single pints for 9. I'm getting hosed

 

Single pints bottles were $8 and change but they had the 4 pint jug right next to them for less than the cost of three single pints.... hmmmm, lets see, lol...

 

Got a bottle of Wix test strips to check my coolant. It is red. Not green or orange. Is this bad? It tested good on all three Wix strip parameters. What kind of coolant do I have and should I switch? This is a new-to-me 145,000 mile old PSD.

 

The new ELC anti-freeze is red. I don't think it's compatible on the 7.3 until the late 99 model year. It eats away at the injector cup sealant and you'll notice fuel in the degas bottle if you let it run long enough.

 

Hard to tell what the red stuff in there is. Might be a specialty coolant or something like Amsoil (usually red). You call on that, but the price of 4 gallons of antifreeze and a few gallons of distilled water, seems to me to be a lot cheaper than injector cups...

 

so you mix it yourself? what ratio do you run? i'm wanting to drain and refill my new truck, never know what has been in there. Thanks also how much of the additive?
