Spark plug replacement is considered one of the least complicated tasks at a shop, but ignorance of what you are dealing with can get you into trouble.
To ensure accurate torque values and to avoid cracking the cylinder block, clean any dust, dirt, oil and fluid from the cylinder block head bolt holes before installing the new head gasket and head bolts. Never lubricate the head bolts with a friction-modified oil. Unless otherwise specified, lightly lubricate the bolt threads with 30w non-detergent motor oil.
With the need to comply with ever-increasing efficiency and emission standards, auto manufacturers have been racing to raise the bar in spark plug performance over the past three decades. The use of precious metals like platinum and iridium in the manufacturing of spark plugs, as opposed to the use of nickel, has resulted in plugs that can last much longer and offer better performance than the spark plugs in circulation prior to the mid-1980s.
As vehicles are lasting longer, the chances the fuel lines will spring a leak are increasing. The main reason metal fuel lines fail is corrosion, but most corrosion starts when abrasive materials start to remove the paint or coating on the line. This can occur at a mounting bracket or from debris kicked up from
Every time a spark plug fires, the spark burns a few molecules of metal off the plug’s electrodes. Over time, this eats away the electrodes and rounds off their sharp edges. The erosion gradually increases the gap between the electrodes, which, in turn, increases the firing voltage required to generate a spark. Eventually the point
Modern passenger and light-duty diesels with ECMs have mass airflow sensors and precisely control fuel delivery. Key to the efficiency and lifespan of the diesel engine is the diesel air filter. A restricted air filter will not affect fuel economy but will drastically affect power output. We asked prominent filter manufacturers for some diesel air
After a faulty ignition coil is diagnosed and replacement is determined, best practices are essential. Here is a list of tech tips when performing ignition coil replacements. • Coils shouldn’t have any visible damage and the boot should be fully seated. While assembling coils to the engine, disregard the coil if you notice any visible
