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 ….
Tech Tip: Diagnosing and Servicing a Coolant Leak
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, coolant will leak past the pump shaft or out of the small vent hole on the housing.
Diagnostic Solutions: Power Steering Pumps
Going Back to the Basics Can Often Resolve Troublesome Power Assist and Noise-Related Issues We often take the commonplace power steering pump for granted until the driver begins to notice a lack of power assist during parking or the pump itself begins to develop an irritating growling or whining noise. Although installing a new or
The Circle of (Engine) Life: The Important Role Water Pumps Play in Engine Preservation…Restoring the Engine to Precise OE Tolerances
Amazingly, up to one-third of the heat energy produced inside an engine’s combustion chambers ends up as waste heat that goes into the block. This heat must be eliminated, otherwise the engine will overheat and self-destruct. The water pump keeps coolant circulating between the engine and radiator to get rid of the heat. The pump

Chrysler & Jeep Cooling System & HVAC Service
Every car make has its quirks, and Chrysler and Jeep vehicles are no exception. In researching this article, we found several examples of heater problems in these vehicles that seem to be fairly common. On 2001 and 2002 Sebring Sedan, Sebring Convertible and Stratus Sedan, plus 1993 to 2002 Chrysler Concorde, LHS, New Yorker and
Tech Tip: What to Know When Coolant Leaks Occur
Engines run hot! Almost a third of the heat energy produced by combustion is absorbed by the engine itself. That’s why engines need a cooling system. The cooling system absorbs the engine’s waste-heat and prevents the engine from overheating and self-destructing.
Management: More New Models, More Repair Opportunities
According to a report in the Wall Street Journal, 2007 will see more new model introductions than any year in recent history. The 2007 model year will bring 61 new models to market, which is almost double the number of new models that typically appear each new model year.
