      Honeywell has announced that its new 
      link hidden, please login to view is now available at all participating NAPA Auto Parts stores across the United States. Solstice yf UV is a low-global-warming-potential (GWP) refrigerant incorporating ultraviolet (UV) dye for leak-detection support in automotive air-conditioning systems.
      This is the first time Solstice yf (R-1234yf) refrigerant with UV dye will be available in the aftermarket.
      The automotive service industry has traditionally used UV dye as a valuable tool to identify and repair air conditioning system leaks. With UV dye incorporated in Solstice yf, the solution provides precise leak detection, shortened service times, accurate repair verification and eliminates call-backs, increasing customer satisfaction, according to Honeywell. Solstice yf UV uses the same UV dye that automakers use on assembly lines and will allow service technicians to save time and money when servicing vehicles that were built with R-1234yf. 
      “At NAPA Auto Parts, we are always looking for opportunities to carry new and innovative tools that help our customers repair vehicles faster and with ease. said Mike Pettyjohn, senior category manager for NAPA Auto Parts. “Honeywell’s Solstice yf UV is exactly that type of product, and it has the benefit of being better for the environment.”
      By the end of 2022, R-1234yf refrigerant will be used in almost 200 million cars on the road globally and in more than 95% of all new vehicles sold in the United States. By 2025, it is estimated that more than 100 million cars using R-1234yf will be on the roads in the United States, significantly expanding R-1234yf servicing opportunities for automotive shops.  
      “As the first manufacturer to offer low-GWP R-1234yf with UV dye to the automotive industry, Honeywell is dedicated to supporting our end-user customers in their environmental transformations while helping them reduce costs and improve customer satisfaction scores,” said Ken West, president of Honeywell Advanced Materials. “With NAPA Auto Parts as our retail launch partner, we are expanding our reach to support customers across the United States, strengthening our commitment to supplying the automotive aftermarket with ready-now solutions that have lower greenhouse gas emissions without sacrificing product performance.”
      link hidden, please login to view Honeywell’s Solstice yf UV is manufactured in the United States and is commercially available today at participating NAPA Auto Parts stores in 8-ounce cans as well as in 10- and 25-pound cylinders.
      Honeywell has invested $1 billion in research, development and new capacity for its Solstice technology, having anticipated the need for lower-GWP solutions to combat climate change more than a decade ago. The product line, which helps customers lower their greenhouse-gas emissions and improve energy efficiency without sacrificing end-product performance, includes refrigerants for supermarkets, air conditioning for cars and trucks, blowing agents for insulation, propellants for personal and household care and solvents for cleaning solutions.
      Customers utilizing Solstice technology have avoided the potential release of the equivalent of more than 260 million metric tons of carbon dioxide into the atmosphere, equal to eliminating the potential emissions from more than 55 million cars for one year.

      The VVT category continues to grow in the automotive aftermarket. These systems are becoming more and more common as manufacturers try to meet tightened fuel-economy standards. When it comes to meeting those standards, variable-valve timing (VVT) is just one piece of the puzzle. As these vehicles exit the factory warranty period, there’s a huge opportunity for counter pros to serve customers’ repair needs.
      Variable-valve timing is the process of altering the timing and/or duration of a valve lift event, to improve performance, fuel economy and emissions.
      On a conventional engine, the opening and closing of the valves is based on their fixed position relative to the timing chain or belt, which is driven by the crankshaft. Without VVT, the valve timing remains the same for all conditions. This means that certain compromises must be made by manufacturers; this is achieved by selecting a specific cam profile. The cam profile affects the valve lift and duration.
      However, an engine equipped with VVT can make additional adjustments, so it isn’t constrained by the cam profile. VVT systems allow for improved performance over a broader operating range. The ability to alter valve timing at any engine speed gives manufacturers the ability to tune for optimal performance and efficiency. The camshaft’s timing can be advanced to produce better low-end torque, or it can be retarded to have better high-end torque as directed by the ECU.
      System Overview
      It’s important to point out that VVT is not just a single part or component – it’s an entire system. There are a number of components that all need to work hand-in-hand in order for the system to function. Let’s talk about some of the components that make up the entire system.
      The part that actually controls the position of the camshaft is the phaser. Cam phasers may feature a piston-type construction, or a vane-type construction. Regardless of construction, they use engine-oil pressure to push against a strong internal spring. A VVT solenoid is used to adjust the engine-oil pressure into the phaser.
      While early VVT systems were active only in higher rpm ranges or under specific conditions, modern systems are actively adjusting the intake and exhaust camshaft positions for the best possible efficiency at all times.
      VVT systems have caused one emissions system to become all but extinct: exhaust-gas recirculation (EGR). Since VVT is able to control the way gasses enter and exit the combustion chamber, there’s no need for EGR systems.
      EGR systems were designed to reduce nitrous oxides (NOx) by recirculating exhaust gasses back into the intake manifold. This causes the combustion temperature to drop below 2,500 F, preventing the formation of these harmful gasses. EGR systems did work, but lacked the reaction time and precision offered by VVT systems.
      Failure Points
      In many ways, engine oil is the lifeblood of the VVT system. Inadequate oil pressure or contaminated oil will hamper system performance. It’s very important that customers are following the manufacturer’s maintenance schedule, and using only the specified type, grade and viscosity of engine oil in their vehicle.
      Clean engine oil is critical to VVT-system operation. The oil passages of a VVT system are like a dead end, and the oil doesn’t flush out the passages all the time. If a piece of debris finds its way into a phaser or oil-control valve, it could be there for a while. Most manufacturers use a metal-screen filter to prevent debris from reaching the variable-valve timing system. Some manufacturers make the screen serviceable but, on some vehicles, it could be inside the oil-control solenoid and almost impossible to inspect or even clean.
      The relationship between the camshaft and crankshaft is critical in today’s VVT systems. The ECU relies on information from the camshaft position sensor and the crankshaft position sensor to determine ignition and valve timing. If either of these sensors produces a faulty signal, the VVT-system performance will suffer. A loose or stretched timing chain or timing belt, or a worn timing guide or tensioner, all could negatively affect the VVT system.

      A leading automotive tool and equipment distributor wanted to make it easier for shop owners, professional technicians and do-it-yourselfers to get the vehicle service equipment and tools they need quickly.
      The result is Wrenchers, a reimagined and rebranded version of the company formerly known as Garage Equipment Supply.
      The new Wrenchers offers more than 12,000 items from leading tool and equipment brands, plus access to more than 50,000 specialty items online at 
      link hidden, please login to view, via phone and through its master product catalog. The expanded lineup includes an array of high-quality lifting systems, specialty tools and equipment solutions including service lifts and parking systems, hand and power tools, tool storage, vehicle diagnostics and various shop essentials, such as wheel service and collision repair equipment. 
      In addition to changing its branding and bolstering its product lines, Wrenchers has relocated from California to a large corporate office and distribution center in Theodore, Alabama. The new location helps Wrenchers deliver products quicker than any other warehouse distributor, according to the company, reaching 98% of the United States with free shipping via LTL trucking, flatbed service or FedEx within one to five days from the time the order is placed. 
      “Not long after we launched in 1996, customers started asking us to offer even more equipment,” said Marco Ortiz, director of factory sales.“Wequickly expanded to include tire changers, wheel balancers, alignment and front-end tools, among others. More than 25 years later, we now serve every facet of the vehicle-maintenance marketplace. With our new website, distribution center and other enhancements, we can offer our more than 350,000 customers more choices, faster delivery, and even better service.” 
       Wrenchers markets its products through multiple distribution sales channels, including retail, e-commerce and independent specialty tool dealers throughout the United States and Canada.
      The company also supports its customers with financing options and an extensive field service network of Wrenchers TechMate reps. These specialists demonstrate, install, set up and service shop equipment systems.
