link hidden, please login to view announced the Cool Car AC Performance Booster, a five-minute service for quick lube and professional automotive service operators. The company said the Cool Car AC Performance Booster delivers an average vent temperature drop of 12.1 degrees Fahrenheit, lowers cabin humidity and speeds cooling without adding refrigerant. The proprietary thermo-conductive synthetic lubricant is designed to address oil fouling inside the A/C system. According to the company, the treatment improves heat transfer, reduces compressor friction and wear, and may extend compressor service life. The service works with R-1234yf and R-134a systems, does not require A/C certification, and uses a dedicated installation tool.
Cool Car AC Performance Booster Field Adoption
The Cool Car AC Performance Booster has expanded into nearly 500 quick lube locations. Dealers have reported take rates of 5% to 10% of car count. Operators report customer demand driven by peak summer heat and longer vehicle ownership, now averaging more than 12 years on the road. Stores also report additional revenue and repeat visits.
“In my career, I’ve rarely seen a product get this kind of reaction from the field,” said Joe Farr, sales director for Groove Technologies. “Technicians are excited to sell it. Store managers are telling us about customers who’ve left five-star reviews on their Jiffy Lube location websites. In some cases, brought in their second or third vehicle the same day to have the service performed. When you have both fast lube operators and customers this happy, you’ve got a winner.”
Field reports document temperature drops as high as 29 degrees, according to the company. Customers have commented that their A/C feels colder after treatment. One district manager reported a 22-degree drop during a store demonstration and said his team plans to position the service as a key seasonal offering during an expected warm summer across much of the U.S.
Pairing with Cabin Air Filter System
The Cool Car AC Performance Booster can be paired with Groove Technologies’ Qik-FIT Premium Universal Cabin Air Filter System. The company said the combination allows operators to offer an A/C performance package.
The Cool Car AC Performance Booster is available exclusively to professional automotive service providers through a Groove Technologies partnership with Service Champ.

Strictly as a word, performance is defined as the act or process of accomplishing something. In the automotive world, it’s often preceded by the word high, to indicate a modification which makes a vehicle perform more like a race car, but even without, it’s often thought of in the same context.
Relating to chassis bushings and mounts, we’ll look at it in both ways. The common link between suspension bushings, body, engine or transmission mounts is what they do and what they are made of.
Their purpose is to allow a minor or controlled degree of movement between two components, while absorbing shock, dampening noise, preventing vibration and preventing metal-to-metal contact between the two components. They can be made of rubber, polyurethane, plastic or metal depending on their application, but rubber is the primary material for production vehicles.
All bushings or mounts are designed to perform in a certain manner, depending on whether the vehicle is designed for luxury, performance or heavy-duty use. The difference in performance comes from the hardness of the rubber (or other material) used in any given component. Hardness is measured by a piece of equipment called a durometer.
Hardness can be related to many everyday objects such as a rubber band, super ball, automotive tires or even skateboard wheels. A rubber band, for example, would have a low durometer reading, while a skateboard wheel would have a higher reading. In automotive applications, not only are mounts and bushings engineered and formulated to meet a specific durometer rating, but all rubber components utilize this scale during engineering, as well such as door seals and O-rings.
Chassis performance, when relating to it in terms of the way any vehicle was designed and built, can be affected by the quality and type of replacement components. Manufacturers that follow original equipment (OE) standards when manufacturing replacement components do so with the intent that the replacement components will be equal to the OE in quality and performance.
This is important because the majority of vehicle owners want their vehicle to perform as it did when new. If the rubber in a replacement component is of a different hardness, a vehicle may not handle or ride as well, or there could be increased vibration transferred from the suspension or drivetrain into the cabin. It all depends on the durometer rating of the rubber.
On the flip side, vehicle performance may improve with different bushings and mounts, which leads me to the high-performance side. With suspension, a common modification is to install polyurethane bushings in place of the OE rubber. The polyurethane bushings have a higher durometer rating, which means they are stiffer than rubber. This keeps suspension components in strict alignment during suspension movement and cornering, which adds up to improved handling. But you sacrifice comfort, noise and vibration levels at the same time.
Polyurethane engine and transmission mounts can improve throttle response and acceleration by preventing excess drivetrain movement, and they handle a greater level of stress, but again you will sacrifice comfort, noise and vibration levels at the same time.
Polyurethane is used for these high-performance applications because it’s easier to customize a specific durometer rating with polyurethane than it is rubber, and therefore a higher rating can be easily attained. Plus, it is more durable and longer lasting than rubber, and it’s not affected by temperature, dirt or oil, all which plague rubber components. Certain oils can affect poly over time, but it takes extended exposure and is uncommon for the most part.
An interesting addition to the mount category has been the modern technology of active engine mounts. Active engine mounts have hydraulic fluid filled chambers inside. They are controlled either by electronics or vacuum, the most advanced of which are ECU-controlled.
The amount of dampening inside the mount is changed to meet operating conditions. With this technology, these mounts can offer comfort, low noise and vibration, along with acceleration and high-performance benefits. It’s the best of both worlds.

The water pump market is evolving fast, with millions of vehicles relying on mechanical or electric water pumps to stay cool and perform at their best.
Mechanical water pumps still dominate most vehicles. However, as OEMs continue to incorporate start/stop systems, hybrids, and electric drivetrains, electric water pumps (EWPs) have gained ground and present real service opportunities for the aftermarket.
When looking for a quality supplier, verify that the pump is thoroughly tested. Also confirm the pump meets OE fit, form and function. Choose suppliers that work with OEMs.
Finally, ensure high-quality materials are used since water pumps face corrosive environments. You want a pump that will last.
Electric Water Pumps for Modern Cooling Systems
link hidden, please login to view offers a full line of link hidden, please login to view for millions of vehicles, all backed by industry-best warranties. Repair shops can have confidence in what they install. Dayco’s electric pumps are direct-fit, bolt-on replacements, so no modifications are needed during installation. They feature self-lubricating, corrosion-resistant bearings compatible with all engine coolants and tapered motor brushes for faster break-in. They also use high-strength seals to prevent leaks.
Installation Best Practices for Electric Pumps
Now let’s talk through four installation best practices, as some common mistakes can happen during EWP replacement.
First, remind your shop customers to flush the system completely to remove any residual contamination. Use a 50/50 mix of the correct coolant and distilled water.
Second, remind customers that reusing old seals or gaskets can cause leaks. Offer to add new gaskets and seals when doing a water pump replacement.
Third, ask the shop if they need a belt, tensioner and pulley when replacing the pump. A systems approach is best since components perform better when replaced together.
Fourth, tell shops that voltage checks are critical when installing electric pumps. Check voltage and grounding before and after. Low voltage can quickly destroy a new pump.
