Water Pump Replacement: Nissan VQ-35 Series
At the top of the list of the most difficult water pumps to replace are those found in the Nissan VQ-Series V6 engines.
10 Things To Learn From Oil Analysis
For most consumers, a preventive maintenance program for their automobile consists of nothing more than an oil change. While a regular oil change is very important, the most critical part of changing the oil is to know when to change the oil.
Automotive Fuel Pumps Continue To Evolve
On most applications, the pump runs at a constant speed (typically 3,000 to 7,000 RPM depending on the design). However, on many newer vehicles pump speed is controlled by the PCM and will vary depending on engine load and speed. The most common type of electric fuel pump today is the turbine style pump. An impeller ring with many small blades is attached to the electric motor inside the pump.
The Evolving Oil Change Market
The only constant in the oil change business is change itself, especially if you’re trying to maintain an inventory of engine oil for all makes and models of vehicles. Since Volkswagen began requiring application-specific engine oil in the mid-1990s, the oil change business has (pardon the pun) “changed.” While many Asian vehicles currently require only
Why Oil Filters Matter To Extended Oil Change Intervals
Neglected oil change intervals can ruin the best engine oils and filters. As engine oil and the filter accumulate miles, they become contaminated with carbon, water and various acids, all of which are a byproduct of internal combustion that will form a film of black, gooey sludge on the interior parts of the engine.
Auxiliary Water Pumps – How One Component Can Upset Your Cooling System Diagnostic Logic
A Mercedes comes into the shop with a complaint of poor heater performance. The driver says during cold mornings that the heater will blow cold while he’s driving to work during rush hour traffic. The car is not overheating and the air is coming from the correct ducts. Your first reaction might be to install a new thermostat and inspect the heater core for a blockage. During a test drive, the system may perform great for you. Is the customer just cold blooded?
Toyota Hybrid Oil Change
Does the thought of changing the oil on a Toyota Prius scare you? Are you afraid you could be shocked with more than 200 volts? Don’t be afraid, changing the oil is not radically different than any other Toyota.
Import Oil Specification Primer
As engine technology has evolved and fuel efficiency standards have tightened, oil specs have increased in importance. Using the wrong viscosity could set a fault code in some applications or interfere with the normal operation of the variable valve timing system.
Servicing Timing Chain-Driven Water Pumps
Automakers are always trying to remove items from the accessory drive belt. This improves the efficiency of the engine and can extend the life of the belt. But where do you put the water pump? Some manufacturers like Ford and Mazda have driven the pumps with a pulley on the exhaust camshaft. Other manufacturers have
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
