48 DIESELTECHMAG.COM MARCH 2016 DIESEL TECH Water-based coolants are quite common, but when it comes to a better alternative that's where Evans Cooling comes in. Its High Performance Waterless Engine Coolant is geared towards light-duty diesel trucks as well as other specific vehicles. Plus it protects from 40 degrees below zero and boils at 375 degrees, so the range is much great- er. But that's just one of the reasons this product is better than water-based coolants. After having a few overheating issues with our LBZ project truck last fall, we went in search for a better solution than to "just add water" when we had a problem. Evans Cooling is one of those companies we've known about for a long time and felt it was time to see for ourselves if its products are as good as they say. Benefi ts It wasn't until we got deep into our research on the High Performance Waterless Engine Coolant that we began to truly understand the benefits over water-based coolants. As mentioned before with that wide range, it really does elimi- nate overheating. It has a boiling point above 375 degrees Fahrenheit and it will not vaporize, thus eliminating overheat- ing, boil-over and after-boil. Another advantage is the reduced pressure. Evans Waterless Coolants generate very low vapor pressures, reduc- ing stress on engine cooling system components. That's an added safety element, and means seals, gaskets and hoses will last much longer. Plus it prevents corrosion and eliminates pump cavitation. And a final benefit is the Waterless Coolant eliminates pre- ignition and detonation caused by overheating and according to Evans improves combustion efficiency while delivering more power. Shop Help After doing our research and talking with other shops, we were sold on Evans and ready to stop our overheating issues on our LBZ project truck for good. Now, changing your cool- ant is obviously a do-it-yourself type project that most owners can do themselves. However the combination of needing a warm shop in the middle of winter to do this, plus our concern about making sure we removed all of the water from our exist- ing coolant led us to Adrenaline Performance in Shelley, Idaho. We lean a lot on our friends at Adrenaline because they're always willing to help, plus our own shops don't have the heat or all the high-end tools and equipment. Step One Adrenaline Performance owner Cam Hulse worked us into his schedule so we could get started. Without a drain plug for the cool- ant we removed the bottom hose and the old coolant began to rush out. Because it's vacuumed sealed it eventually stopped, but then when we removed the cap it once again began to flow quickly. Manny Rodriguez, a technician for Adrenaline Performance, then hooked up an air nozzle and was able to blow out any excess that was left, which actually was quite a lot. It is recom- mended that high volume air is used, rather than high pressure. Step Two The instructions stress over and over the impor- tance of getting all of the water out before adding the new coolant. Evans even goes so far as to offer EVANS COOLING Waterless Engine Coolant TESTED N o . 0 0 0 1 6
