Your Volkswagen cooling system plays a critical role in keeping your vehicle in optimal working order. The job of the cooling system is to maintain the correct temperature of the engine via circulation of coolant throughout the engine. The coolant picks up excess heat and passes it through the radiator, which cools it using air. The coolant then feeds into a thermostat valve to regulate circulation via a heat detector and regulates external air-cooling fans.

The cooling systems in Volkswagens are made up of 3 important parts: the water pump, the hoses along with the thermostat, the radiator, and the sensors.

Volkswagen Water Pump

The VW water pump manages the VW’s cooling system’s pumping operation, which keeps the coolant mixture in motion. The standard VW water pump is gear or belt-driven. In addition, there are a few instances in other vehicles where an extra electric water pump is utilized to enhance the cooling and movement of the coolant combination. Quite possibly the most essential element of the pump’s functionality is the drive belt; also known as the timing belt on a majority of new automobiles. However on slightly older models, the pump and belt are located on the outside of the vehicle. They both operate off the primary crankshaft pulley utilizing a “V” of flat belt.

The VW water pump is maintained when the coolant or drive belt is being replaced, or tension adjustment on the external type.

The timing belt powered-pumps ought to be switched out whenever changing the timing belt and tensioner.

Volkswagen Hoses

The Volkswagen cooling system is made up of a number of hoses, such as the radiator hose, the control valves, the expansion tank, and the heater core. These parts are subject to high heat temperatures and have to be replaced fairly often.

Scheduled maintenance of the cooling system should involve replacing all hoses and coolant, as well as any unplugged or leaking parts. The hoses should be checked every 6 months to see if there are any abrasions, cracks or leaks. A VW professional who is well aware of all the components of your Volkswagen should perform all repairs on your Volkswagen.

Volkswagen Radiator, Thermostat and Sensors

The temperature controls on the VW’s cooling system consists of coolant temperature sensors, thermostat, cooling fan(s), radiator, expansion tank cap, and fan clutch. Although these parts operate independently of the engine, their job is to maintain the proper temperature of the engine. Each component does their job of maintaining the engine via a series of control signals.

Maintenance of the sensors require very little work. The sensors only have to be cleaned internally and externally. Always check your owner’s manual for specifics.

At the 2015 New York International Auto Show, Volkswagen introduced 4 Beetle Special Edition concept cars that will help commemorate Volkswagen of America’s 60th anniversary. They are the Beetle Convertible Denim, Beetle R-Line, Beetle Convertible Wave, and Beetle Pink Color Edition. They also introduced the All-wheel-drive Golf SportWagen Alltrack set for production in 2016.

There are some visual and technical variances between the Golf SportWagen and the Alltrack. They include the 4MOTION AWD system, over 1” higher ground clearance, wheel arch moulding, body protection by flared side sills, newly designed bumpers, and an upscale interior.

The 4MOTION AWD system employs the newest generation Haldex-5 coupling, set in motion through an electro-hydraulic oil pump. In ordinary driving conditions, the Alltrack performs like a front-wheel-drive car to improve fuel economy. However when the system registers wheel slide, as much as 50 % of the drive torsional power can be redirected to the back wheels. In addition to the Haldex coupling that functions longitudinally, there are electronic differential locks (EDL) at the front and rear axles. These EDLs operate laterally together with the electronic stability control system. The system quickly brakes a wheel that is sliding, allowing for continuous and stable transfer of drive power to the wheel on the reverse side.

In combination with the increased ground clearance, this 4MOTION all-wheel AWD system helps to provide the most recent Golf SportWagen. The off-road functionality and load-carrying capacity of a compact SUV is held together with the on-road behavior, and fuel economy of a compact wagon.

Beetles in the U.S. are powered by 1.8- and 2.0-liter turbocharged and direct-injection TSI gasoline, with engines producing 170 and 210 horse power respectively. Beetles also come prepared with a 2.0-liter TDI® Clean Diesel engine that produces 150 horse power and achieves an EPA estimated highway fuel economy. Specifically receiving a fuel economy of 40 mpg and 41 mpg for the Beetle Convertible.

Beetle Convertible Denim features a fast opening power soft top with a dark blue, textured fabric resembling denim.

Beetle Pink Color Edition is a limited edition Pink Metallic Volkswagen to test the market response for this color VW. This edition will feature the striking R-Line front and rear bumper designs.

Beetle Convertible Wave is designed to enjoy the summer, whether in the Hamptons or in Santa Monica or where ever there is lots of sun to go topless.

A 217-hp 2.0-liter TSI engine that makes an extremely sporty statement powers this Beetle R-Line concept car. Learn more about the latest Volkswagen offerings at Chapman VW Tucson.


Sportier Styling in Step with the Times

A more aggressive design is part of the United States marketing plan for Volkswagen in the near future. The effort begins with a new crossover, as yet unnamed, that will soon go into production at VW’s Chattanooga, Tenn., manufacturing plant. About the same size as an Audi Q7, it will be the biggest vehicle VW has ever produced. It will feature an aggressive, sculpted body style that incorporates a new grill and sharp angles to deliver a bold statement.

Bold Move to Increase Market Share

Although VW has been around in the U.S. for more than six decades, the company has a smaller than average market share. This is much lower than the success the company enjoys in Europe and China, where sales are brisk and reach well into double digits in market share. The company held focus groups in the U.S. and found that customers demand a less conservative look than the one the company has been supplying in vehicles like the Passat and Golf. Further customer involvement will be key in deciding future designs, according to a VW spokesman.

Look for New Tiguan in 2017

Keep an eye out at your Volkswagen in Tucson dealer, Chapman Volkswagen for the all-new Tiguan a little more than a year from now. It will be longer than the current version with more modern lines and a shorter front porch and rear deck. It will feature more cargo room than current models. Taillights that wrap around from the side to the rear and a sportier grill will add to the new design.

New Golf Boosts March Sales

Despite slower overall sales, the release of the new Golf R provided the best March for the little hatchback in 15 years. The Golf sold just over 4,600 units in America last month. VW expects those sales to continue to increase with the release of the Golf Sportwagen, headed for Chapman Volkswagen later this month. The Golf Sportwagen will come with a diesel option that will produce a little more than 43 miles per gallon on the highway. That’s the best fuel economy for any gasoline or fuel-powered SUV. The Jetta had the strongest sales of all VWs, selling just over 11,000 vehicles in March. The Passat, built in Tennessee, sold almost 8,000 cars, spurred by the release of a new Limited Edition trim package.
