While preparing to do a Radiator Flush on my '03 Ford Power-stroke 6.0 Diesel, I looked high and low for the specialized Coolant formulated for Diesel Engines and Cast Iron Blocks. I didn't want the premixed stuff so many companies are now only offering. I prefer to mix my own, that way I know what I'm putting in my expensive Diesel motor. It seems companies are offering premixed coolant only to make more money from us, the customer. After all, do you really know what mixture you are getting?
When I mix my own making a 50/50 mix of antifreeze and distilled water, I know I am getting exactly that. And because the straight stuff is only a couple dollars more than the premix, you are getting way more for your money. Coolant of any type is not cheap by no means anyway, why pay what comes out as $4-5 per gallon for distilled water that you can buy for as little as .89 cents at the local market.
In the long run, you make out better buying and mixing your own anti-freeze coolant. Plus when you buy in by the case, you have plenty left over for another flush years down the road. This Zerex is made for Diesel engines and certified by CAT EC-1, which regardless of color, if your coolant is going into your Diesel Engine, it better say CAT EC-1 somewhere on the bottle or don't use it in your 20k motor.
