Coolants: What do I need to know about green and red antifreeze? Nothing! Just forget about them and install “EVANS’ Waterless Coolant. It’s good for the life of the engine and doesn’t boil, unless you get your engine over 375 degrees. Yes, Evans is expensive! However, since there will be no pressure in the radiator, heater core, or all of the hoses, they will all last longer. Not only will they last longer, there is no corrosion, so the engine block, water pump and cylinder liners will all last longer. Think about this: You just topped a mountain and feel the need to check the coolant level in the radiator. Well, there’s no need to worry about the pressure pushing the coolant out of the radiator and burning you, because there IS NO pressure. That’s why it WILL NOT blow out of the radiator. The pressure created with green or red antifreeze is from the coolant boiling in the head and next to the cylinder liners. Evans doesn’t do this because of its exceptionally high boiling point. Those of you who are mechanically-inclined have seen how liner pitting can put coolant into the oil pan. Well, not with Evans! The liners WILL NOT pit, so premature engine failures are almost eliminated.
Steam created by boiling antifreeze has a “blanket barrier’ effect and doesn’t show up on the coolant temperature sensor. We do not know how much boiling takes place above the piston in the head because the sensor is not in that area. However, there are more cracked cylinder heads on the electronic engines than we ever had with the older mechanical engines, because the newer electronic engines run hotter. SO, let’s try to eliminate the head cracking issues by using Evans Coolant and 180 degree thermostats and when it’s time for a new radiator, by installing our high-flow dimpled-tubes rads (which also have many MORE tubes AND more “fins-per-inch”). This way, you will not have to stare at the coolant temperature gauge on every hill!!
FUEL SAVINGS: Evans Coolant has been known to improve fuel mileage. I have asked “Why is that?!” for about the past five years! Evans, with the 375-degrees boiling point usually installs 205 degree thermostats, which raises the temperature of the fan coming on by 20 degrees. I’m old school: I like 180 degrees, or up to 205 degrees pulling a mountain with 80,000 pounds and 700 horsepower, which is why we at Pittsburgh Power have stayed away from Evans Coolant for so long. WELL, last summer at the Dallas Truck Show, Evans’ booth was right across the isle from our booth, and at the end of the truck show I asked them why I can’t use a 180 degree stat with the coolant, and they said you CAN. I can?! “Why didn’t you tell me this FIVE years ago?!”, I asked! I never could figure out why higher coolant temperatures could improve the fuel mileage. Well, it turns out the fuel savings results from not allowing the fan to come on at 215 degrees. Well, that is no problem! When we install our high-flow radiator along with 180 degree thermostats, the truck usually never sees 205 degrees, so the fan never comes on. That is why we see an improvement in fuel savings. Always keep this in mind: A thermostat takes 15 degrees to fully open, so a 190-degree stat is fully open at 205 degrees, and a 195 stat at 210 degrees, which is too hot for me.
Remember that silicates are corrosion inhibitors, and are present in green and red antifreeze. They can cause problems such as too much of a buildup on the liners and in the water jacket, which inhibits cooling. Silicates are known to fall out of antifreeze, and on the Cummins BC4 Low-Flow cooling system, they will clog the screens in the coolant tubes going to the aftercooler. Evans does NOT corrode, so there are NO silicates or phosphates in Evans Waterless Coolant. Yes, this stuff IS expensive, priced at $47.95 per gallon, and it takes 3 to 5 hours to drain, clean the cooling system, and install the Evans Coolant. Think about this: With the larger radiator, a bypass oil filtration system such as the OPS-1 Eco-Pur and the Spinner 2, Fleet-Air Filters, our quiet performance mufflers that don’t hold soot, and Evans Waterless Coolant combined, your engine just might run for 2 million miles or more!
Wheel Alignments: As of July of this year, Pittsburgh Power became an MD Alignment authorized shop. If you listen to Kevin Rutherford on the XM-Sirius Road Dog Radio Show, you will know the value of the MD Alignment system. Mike Beckett is the founder and inventor of the MD System and is known throughout North America as the leading expert on tire wear. He spends most of his time on the road finding cures for the OEM truck manufacturers and fleets. I have known Mike for the past four years and have always been impressed by his knowledge of suspensions and alignments. In my 64 years, I have NEVER met a person so well-versed on this subject. Most of the trucks we see in our shop have in excess of 700,000 miles and there is wear in the suspension system. Most of the time, it’s the track bars and on Freightliners, the U-bolts that hold the rear suspension up are loose. How can you get tire mileage and fuel mileage when the differentials are not tracking straight down the road? When your truck is in our shop it only takes one hour to check your alignment. Improper alignment will rob you of thousands of dollars in fuel mileage and tire life. All you have to do is tell our service writer that you want your alignment checked.
