What’s Your Belts and Hoses IQ?
Every motor vehicle on the road has one or more belts, and dozens of different kinds of hoses (coolant, fuel, vacuum, power steering, brakes, windshield washers, etc.). Being familiar with these products allows you to get the correct replacement belts and hoses to match your customers’ needs.
Subaru Service Essentials
Building a planned process for servicing a customer’s vehicle is something to consider. You can start the service sales process by becoming informed on what you can do that will not affect a customer’s factory warranty, then determine the minimum necessary to maintain the warranty so you can service the customer from day one.
Keeping Engine Temps In Check
Keeping an engine cool is no easy task. Nearly a third of the heat released by combustion ends up as waste heat in the engine block and cylinder heads. All that heat has to go somewhere to prevent a meltdown, so coolant circulating through the block and heads soaks up the heat and carries it to the radiator where airflow absorbs the heat and carries it away.
A New Look at Cooling System Technology
While changes in modern cooling system technology might not be apparent in day-to-day servicing, the fact is that auto manufacturers are continuing to increase fuel economy and power output by changing how the cooling system operates.
Hybrid Vehicle A/C Service Basics
As you may know, the air conditioning compressors in many hybrid vehicles are operated by an electric motor instead of a drive belt. The motor’s insulated windings are immersed in the compressor’s lubricating oil. The oils used in these compressors are formulated to have high dielectric properties, that makes them non-conductive. Denso has recently produced
Understanding Air Filter Fundamentals
Air filters remove dirt by trapping contaminants as the air flows through the filter media. The percentage of particles removed is a measure of the filter’s efficiency. A good quality air filter generally trap upwards of 98.5% of the incoming dirt.
The Ins and Outs of Battery Testing and Service
Modern battery technology is changing the way we deal with battery testing and replacement. To illustrate, absorbed glass mat (AGM) batteries are, in some applications, replacing the conventional "flooded" wet-cell batteries.Flooded batteries consist of positive and negative plates suspended in an electrolyte consisting of about one-third sulfuric acid and two-thirds water. The flooded battery is
Battery 411: Testing, Charging and Replacing a Battery
In recent years, the electronic content in vehicles has multiplied several times over. More electronics means more demand on the battery and charging system. A weak battery or low system voltage due to a charging problem can cause all kinds of havoc with the on-board electronics.
Mode $06 Diagnostics Offer Added Insight, More Information
What’s the one thing you always want to avoid when diagnosing and repairing driveability and emissions problems? Comebacks. Nothing is more frustrating than to "fix" a customer’s vehicle, and then have it come back a few days or weeks later with the check engine light on and displaying the same or a new fault code.
Modern Gasket Technology and Installation
When it comes to engine gaskets, the modern technician is often faced with a dizzying array of gasket technologies. The practices that apply to older engines often conflict with those applied to modern engines. Let’s start by separating gasket technology into three different eras.
Performing Cylinder Head Gasket Repairs
Cylinder head gasket failures are one of the most common mechanical issues facing today’s modern technician. One reason head gasket failures are common is because the cylinder head gasket itself can become a wearing part.
Subaru Service Essentials
In this age of extended service intervals and exaggerated claims of longevity with little maintenance, selling service at a fair price is becoming more difficult. To help boost service sales, consider building a planned process for servicing your customers’ vehicles.
