Zerex Extended Life Red Heavy Duty (HD) Concentrate Antifreeze/Coolant 1 GA

Flushed my truck and put this in. Coolant filter installed. Hate the stupid green. Some shop I had taken my truck for some work done topped my truck off with green. Had to flush it out. I had Motorcraft gold in it, but switched to this. I pay attention to coolant PH, coolant additives and things. I prefer to keep my coolant clean and the PH correct. With the filter, My truck is just like a HD Highway diesel, just keep the filter changed and on top of PH and engine/ water pump last long time. So do hoses when they aren't corroding from inside.Coolant was a good price when I bought it. A little cheaper than autoparts wearhouses locally wanted 20$ something for coolant.

Can't go wrong with this, it's an OAT coolant so make sure your truck needs an OAT coolant.Because if you mix with the older HOAT standard you'll end up with a radiator full of Yello.So, you're warned.

Use it for my caterpillar skid steer works perfectly

Takes a minute to get used to the taste, but other than that works just like any other coolant

It’s wet and keeps my ram 2500 cool

Fresh shipping great product great bargain

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.

Fit the Cummins requirements for the antifreeze/coolant.
