Tech Tip: Shim Calms Chirping Noises in Honda Models
Some Honda owners may complain of a chirp from the lower timing belt area. The noise is most often noticed at idle, usually after the engine has warmed up. The probable cause is the idler pulley mounting surface is tilted, causing the edge of the timing belt to rub against the side of the pulser flange on the drive pulley (gear).

Tech Tip: Noisy Infiniti Water Pump Flange
An Infiniti driver may complain of a screeching noise when the vehicle is first started in the morning. The noise dissipates once the vehicle is warmed up. This condition may occur if the water pump had recently been replaced and the fan coupling to water pump flange bolts were not torqued correctly.
Tech Tip: Water Pump Plastic Impeller Failure
Plastic impellers erode because of steam in coolant. Head gasket leaks and cracked heads allow aeration of the coolant, which develops pockets of super-heated air that destroys the impeller.

Tech Feature: Replacing Water Pumps as Preventive Maintenance
In today’s import repair market, it’s not uncommon to see a vehicle with well over 200,000 miles on the odometer that still is in cosmetically and mechanically "great" condition. The importance of this trend is that many parts that were formerly being replaced on an as-needed basis are now being replaced on a preventive basis. Water pumps are a good example because they serve as an idler pulley on many engines equipped with timing belts and, due to accessibility issues on many transverse engines, should be replaced during any ….
