Proper Coolant Maintenance Matters

Check your coolant when you check your oil

(June 3, 2021) – Heavy duty engine coolants are one of those things you might not think about as long as they’re working properly – until you have an overheating problem. By then, it’s probably too late to take the measures necessary to prevent the problem in the first place. Of course, you should follow the OEM’s recommendations in the choice of coolants for the vehicles in your fleet, as well as its maintenance requirements. But best practices in coolant system management suggest going above and beyond the basics.

Fleet maintenance managers are usually diligent about preventive maintenance with their engine oils – for example, pulling samples and running analyses for particle contamination or degradation. But coolants don’t always get that level of attention. They should. One way to implement a routine coolant preventive maintenance program is to schedule checks at the same time as your regular oil checks. Use a refractometer to check the coolant’s freeze point and check the pH levels as well to make sure both are within acceptable limits. If they are not, it could be an indicator of a deeper problem that requires pulling a sample and doing a thorough analysis. Also check to see if the coolant needs topping off. Some evaporation is to be expected, but a big drop in the coolant level may be an indication of a leak in the cooling system. Finally, pressure test the system to make sure the radiator cap is functioning properly.

It’s not uncommon for fleet shops to have several coolants in stock, especially if the fleet has a mix of engine types from different OEMs. One OEM may require coolants containing nitrites while another may specify nitrite-free products. This adds to the complexity of managing coolants and is another reason to have an ongoing and robust preventive maintenance program.

Coolants have become quite sophisticated in their chemistry as they have evolved. In the early days of trucking, just air and water were used to try and keep engines cool. But air cooling alone required too much power to run fans to prevent overheating. And water was problematic in areas where the winter temperatures dropped below water’s freezing point, not to mention the risk of rust and corrosion. Adding glycol to water enabled coolants to operate in a wider range of temperatures, while inhibitors were added to help prevent problems with rust. Over the years, inorganic additives such as phosphates and silicates were introduced to help prevent corrosion by adding a protective layer over all metal surfaces. However, these additives tended to deplete quickly, leading to a relatively short service life for the coolant. That led to the development of organic acid technology inhibitors, or OATs, which target only those areas where corrosion is beginning to occur. Today, the life of a coolant with OATs can be as much as one million miles, or even more when treated with an extender.

Coolants today also do much more than simply prevent overheating. For instance, modern engines have been designed to meet strict emission standards with exhaust after-treatment systems that include exhaust gas recirculating (EGR). In order to do its job, the EGR has to reduce the exhaust temperature, which contributes to more efficient combustion in the engine, and that in turn reduces nitrogen oxide and particulate matter in the exhaust. In order for the EGR to do that, it needs to be able to cool the exhaust gases. Diesel engine coolant is generally used to cool the EGR before it recirculates the exhaust back into the engine.

This simply underscores the need to make sure your coolants are maintaining the proper chemical balance and not degrading. Routine preventive maintenance checks will help prevent problems not only with cooling systems, but with all the engine and exhaust system components that rely on coolants for proper functioning.

The ISOCLEAN System is Right for You!

May 13, 2021 — How important is the cleanliness of oil when it comes to your equipment?

Considering that 82 percent of mechanical wear is caused by particle contamination, it means everything. The two leading types of contamination in oil are particulates and water. Dirt and contaminants are the leading cause of hydraulic system failures.

Often, these contaminates are microscopic – they cannot be seen with the naked eye. Still, they can be quite harmful, causing abrasive wear, erosion, and fatigue of equipment. As little as one teaspoon of dirt in 55 gallons of oil equates to about a billion particles 4 microns and larger.

To maximize productivity and component life, equipment manufacturers machine component parts to precision levels. Oil needs a cleanliness level to protect the tightest machine clearance on your equipment.

Using clean oil that meets your equipment manufacturer’s requirements has multiple benefits to the component with the No. 1 benefit being an increased component life.

The best way to reduce contaminate-caused wear is to start clean, monitor lubricants and stay clean.

At Shrader Tire & Oil, we believe in starting clean. There is no need to worry about the hassle, expense, and risk of pre-filtering new oil. Trust Chevron ISOCLEAN Certified Lubricants.

Our ISOCLEAN program uses different testing methods to ensure the cleanliness level is where it needs to be at delivery. Once you have ISOCLEAN Certified Lubricants in your system, the next step is to ensure your equipment is protected while in production. To do that, utilize the Chevron LubeWatch program.

Finally, STO encourages staying clean with effective lubricant management.

Earth Day 2021:

An Inside Look at Tire Retreads

Truck tire retreads are not just part of the story at Shrader Tire & Oil, they deliver huge savings to fleet managers and owner/operators and have a massive impact on the environment.

Today, April 22, is Earth Day, but in the truck tire retread industry, we do not wait for a special day to think about the impact we are having on the environment. Every day, in every way, our retread plants are having an impact on our surroundings.

For example, retreading conserves oil. The synthetic rubber components in a new medium truck tire require approximately 22 gallons of oil, but it takes only seven gallons to retread the same tire.

It is also estimated that nearly 300 million tires from cars and trucks are thrown away by Americans each year, but the use of retreads saves hundreds of millions of gallons of oil, and millions of tires continue a useful life rather than being consigned to a tire pile or landfill.

Retreading truck tires in the U.S. reduces carbon emissions by 396,000 tons, or 70 percent annually. Finally, nearly 40 pounds of raw material including rubber, steel and carbon black is saved for every retreaded tire manufactured.

Shrader Tire & Oil is the premier tire and lubricant distributor in the Midwest. With locations in Ohio, Michigan and Indiana, Shrader has 15 truck tire and fleet service centers, two state-of-the-art Michelin retread plants and a bulk lubricant operation and a 24-hour emergency road service network.

It’s a Birthday Celebration at STO –
73 years and Counting!

APRIL 19, 2021 – In the spring of 1948, Jim and Bernie Shrader founded Shrader Tire & Oil in Toledo, Ohio.

A true family business, Jim and Bernie’s children Jim Jr., Gerri, and Patti filled roles in the company after school. In the evenings, Jim Sr. would instill the importance of values like honesty, integrity and commitment as the family sat around the dinner table.

The business has progressed over the years. Now with 15 truck tire and fleet service centers, two state-of-the-art Michelin retread plants, and bulk lubricant operations larger than ever, Shrader Tire & Oil has become the premier tire and lubricant distributor in the Midwest.

Happy Birthday STO!

What Causes Truck Tire Misalignment?

Wondering what causes your truck tires to misalign?

Tire misalignment can be caused by anything from:

  • Road conditions — Since trucks often drive through rugged terrain, rough road conditions can make the wheels especially susceptible to misalignments
  • Potholes and bumps — Events like hitting potholes and bumps in the road can immediately knock your truck out of alignment.
  • General wear and tear — Every time you drive your truck, you are subjecting it to massive amounts of torque and friction, which results in slow and gradual degradation of its components. Over time, pressure on shocks, springs, and tires, can cause them to slowly slip out of alignment.

​No matter the cause, when your truck starts pulling to either side or you feel a vibration in your steering wheel, Shrader Tire & Oil can set your truck back on track.

We provide alignments in seven convenient locations, including: Cincinnati, OH; Columbus, OH; Newark, OH; Toledo, OH; Detroit, MI; Warren, MI, and South Bend, IN.
