Zerex Extended Life Nitrite-Free HD 50/50 Antifreeze/Coolant 1 Gallon - Prediluted & Ready-to-Use Review

I ordered 2 bottles and one was only half full and leaked everywhere. They wrapped her in a bag and the mess was everywhere.

I needed coolant for my Porsche 911 and ordered this particular brand and it works great. Revain sent it to me quickly and well packaged.

AMAZING THING! If you have PSD 6.0 and are using a Ford Gold or any other, you don't have to worry about silicates clogging your EGR or oil cooler. You will need 3 gallons for this. distilled water and 3 gallons of Zerex ELC. This is the EC-1 rating for those wondering. Highly recommended for other PSD owners.

This is the correct coolant to replace my Porsche. I've owned it for five years and have never added coolant. This started to bother me and I found it to be the most economical product in this case. Really good for the price. I'm confident of using it in an expensive engine. I'm glad I bought it.

If you are looking for a long life diesel engine coolant for your drilling rig that is pre-filled and can be topped up after a number of years, then this is for you. Meets the latest cavitation protection requirements. 12 gallons at a 50/50 mix completely filled my class A bus.CAT 3126E 330 hp. It took 6 gallons of distilled water from Walmart.

For Ford 6.0L Diesel after thorough cleaning with chemical coolant. Never mix coolants and never use silicate-based coolants in a 6.0 liter vehicle. The silicate-based coolant falls out and clogs the oil cooler with slime/sludge, eventually causing the oil cooler and EGR cooler to fail, potentially leading to engine damage. Flush the cooling system thoroughly and use this antifreeze.
