Ahhh.. risking a highjack I suppose, so please forgive me .

Have you tried removing the fan? I assume you're referring to their technique to rid yourself of the water by boiling it off..

Then there is their alternative: Did you use the stuff (almost as expensive as the coolant itself) to remove the water prior to pouring in the coolant?

Thx,

I thought about removing the fan but haven't done it, my luck is I'd put a hole in the radiator....

I actually have extra coolant so I can do that too, but I'd rather just drain this into a clean container and set a propane torch or two under it.

 

Pardon my ignorance guys , but what do the acronyms SCA and DCA mean? I'd like to know as I'm thinking it's about time to change my CTD's anti-freeze fairly soon. I was also thinking about using some of the 5-yr stuff too.

Thanks,
Steve

 

I use Evans Cool in everything. It only seems pricy, but when water pumps last forever, radiators never need cleaning, and hoses never fail from internal rot; it pays for itself after the third year. I convert once, and have some rigs that have been running it since 1992, and will never have it changed again as long as I own them.

The other advantage of Evans Cool is that it is a higher viscosity than water and anti-freeze, so blowing headgaskets at high combustion pressures becomes a thing of the past. It also does not cavitate and that solves the problem of cracking the head between the exhaust valves on the 98.5 through the current engine series rigs when you turn the ponies up over 450 and work them really hard routinely.

 

How do you normally eliminate the water RCW?

SCA is supplemental coolant additive.

 

DCA is Fleetguard's brand name for coolant additive. Not sure exactly what it stands for but assume it's probably a twenty-three letters long chemical name.

Diesel Coolant Additive

If you choose to use a SCA package stay with a single brand and type. The Fleetguard DCA requires Fleetguard test strips due to the unique chemistry. Regular SCA (often called Nalcool) is the most common.

Bill's link to www.imcool.com is a real good source of info, especially related to anti-freeze on the article link he posted. I also found some very interesting reading on "global warming" with several articles pointing out how unlikely it really is happening (I've long had doubts about it too). Anyway, thanks for clarifying the acronyms.
