Honda Tech Tip: Dealing with EGR Issues
Exhaust gas recirculation (EGR) has been used for years to control combustion temperature to prevent spark knock as well as control NOx emissions. For the most part, these systems were trouble-free and required service only if you were dealing with a spark knock issue, or if the valve opened too early, resulting in a tip-in acceleration stumble, or the more common, bad idle quality caused by the valve not closing completely at idle.

Tech Tip: Volkswagen Coolant Pump Leakage
Coolant pump seals are designed to use coolant as a lubricant. This design intentionally uses a small amount of coolant to coat the seals during pump operation. Any excess coolant that accumulates will exit the weep hole when the engine cools down. Minute traces of coolant or lubricant residue around the weep hole is not evidence of a faulty pump. Do not confuse a leaking coolant pump with one that is functioning as designed.

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.
