How Long Should A Water Pump Last?
The service life of most original equipment water pumps should be 100,000 miles or longer. Some cheap replacement water pumps, however, may not last 30,000 miles before they start to leak.

The Engine Thermostat: Understanding Electronically Assisted Thermostats
The engine thermostat has been an important component in automotive internal combustion engines for almost a century. The engine thermostat helps to speed warmup and reduce cylinder ring wear. Today, the engine thermostat plays an important role in increasing engine combustion efficiency and reducing emissions. To accomplish that task, engine thermostat functions are controlled by the engine’s electronic control unit (ECU), ensuring precise regulation of temperature based on the engine’s loads.
Audi Direct-Injection Issues & Carbon Deposits

Addressing Extended Oil Changes on Modern Vehicles
Auto manufacturers, in general, are continuing to reduce vehicle maintenance requirements by extending oil change intervals. But extended oil change intervals are a mixed blessing. On the upside, extended oil change intervals are conserving precious oil and reducing carbon emissions. On the downside, many vehicle owners are forgetting to check their engine’s oil level between
