Audi Tech Tip: Diagnosing Noisy Power Steering
Noisy power steering on an applicable vehicle may be caused by the following conditions: 1) Air drawn into the power steering pump if the power steering fluid is below the minimum mark during cold conditions; and 2) If any system components have been replaced or disconnected and the system filling or bleeding procedures were not carried out properly ….
Tech Tip: Diagnosing a Faulty Water Pump
The water pump is one of those parts that no engine can run long without. If the water pump shaft seal leaks, the cooling system will lose coolant and the engine will overheat. That means a breakdown – and a sale of a replacement water pump. The water pump circulates coolant between the engine and radiator to keep the engine from running too hot. Almost a third of the heat produced by combustion ends up as waste heat absorbed by the ….

Tech Tip: Inspect the Cooling System When Replacing the Water Pump
Water pumps work hard. As the miles add up, so does the wear and tear on the pump shaft bearing, seal and impeller. Erosion inside the pump can wear away the vanes on the impeller, causing it to pump less efficiently as the impeller is eaten away. This may lead to engine overheating on hot days or when the engine is working hard. If the water pump seal becomes worn ….
Management: Vehicle Maintenance Equals Increased Fuel Efficiency
With gas prices inching above the current national average of $3 a gallon for regular gasoline, the news of a vehicle that achieves 130-150 mpg would be music to anyone’s ears. Enter the highly fuel-efficient Loremo concept car. The German automaker plans to begin production of the car for European markets in 2009 and for the U.S. a year later ….

Tech Tip: Are You Unnecessarily Replacing Starters and Alternators?
How many starters and alternators are replaced unnecessarily every year because of misdiagnosis? Nobody knows for sure, but suppliers of both new and remanufactured rotating electrical parts tell us more than half of their warranty returns have "no fault found" when the parts are examined. Many of these returns are from DIYers who lack diagnostic know-how, but some are from professional technicians who apparently lack the ….
