Review: A must have for any car - Good price
Review: Great Diesel Coolant and Cheaper by the Case (Way to go desertcart) - 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.

## Questions & Answers

**Q: can i run this in my 2008 jeep patriot**
A: Formulated for Cummins, Detroit, John Deere, International & other Diesel Engines.  Not sure about your jeep patriot.

**Q: Is this dex cool? I know its a pink color nd i thought dex cool was pink is dex cool orange?**
A: This product is not DEXCOOL. This is intended for heavy duty trucks, most often larger than passenger vehicles. If you are looking for the DEXCOOL formulation, we suggest using the Valvoline Zerex DEX-COOL Antifreeze/Coolant, Ready to Use - 1gal (ZXELRU1).

**Q: Would this work with Toyota Card?**
A: We will need a little bit more information to make an accurate recommendation for this vehicle. Please give us a call at 800-832-6825 option 5 to discuss this application in further detail.

**Q: What color is this coolant?**
A: This coolant is a Pinkish Red color. it is a more economical alternative to Caterpillars EC-1 Rated coolant and will mix with other EC-1 Rated coolant. This coolant was used to Replace Fords Gold coolant in my 06 Power stroke Diesel as it has a longer life and will not crystallize in crucial components such as the Oil cooler. Hope this helps
