Diesel Engine Service, Tools & Equipment
Diesel engines are a popular alternative to gasoline engines because of their good fuel economy and torque. More than 55% of heavy-duty pickup trucks are now powered by diesel engines, as are 85% of Class 5 to 7 medium-duty trucks. The GM Duramax, Ford Powerstroke and Dodge Cummins Turbo Diesel engines represent the bulk of
Timing Belt Replacement: Tried and True Repair Method Works Every Time
and below the intake manifold. When this unit fails, it tends to look like the head gaskets are blown. The oil mixes with the coolant and so on, leading to catastrophic engine bearing failure. Saab recommends flushing the cooling system with Shout, a cleaning agent found in many stores. Saab also recommends changing the timing
Diagnostic Solutions: Oil Filters… Are Working Harder Than Ever to Supply Clean Oil to Vital Engine Parts
Although oil filtration isn’t a new science, it’s important to remember that modern engine technology is placing new demands on oil filters. At the very least, modern engines require extremely clean oil for maximum reliability and longevity. But, more important, the use of synthetic lubricants and on-board monitored oil change intervals has allowed manufacturers to
Engine Diagnostics: Mazda
We’re going to take a look at the Mazda line of cars and trucks with an eye on driveability service and diagnosis. In particular, we’ll look at some driveability problems that may result in an illuminated check engine light, as well as some problems that will illuminate the light but may not result in a
Pumping Oil
For me, sourcing automotive chemicals and motor oils goes all the way back to 1957 when I worked at my corner service station. Since we were a small town without a local parts jobber, we bought our oil additives and chemicals from an out-of-town distributor. Our gasoline and motor oil came from our local-branded petroleum
Power Options: Restoring a Vehicle to Like-New Performance
Replacing a worn or broken engine on a customer’s vehicle can be a very sensitive subject for many independent shop owners because it’s a time-intensive and possibly high-liability service. After a replacement is done, a shop’s greatest fear is that a minor ticking noise or oil leak may ruin the profitability of the engine replacement.
TechTalk: Grabbing Dodge Diesel Service ‘by the Horns’
With the massive number of diesel trucks that have hit the roads since around 1998, I believe there is an enormous amount of potential work for independent shops. One fact I thought was amazing is DaimlerChrysler claims that 70% of the Dodge Ram 2500 and 3500 truck market since 2003 is equipped with the 5.9L
Component Connection: The Circle of (Engine) Life
Amazingly, up to a third of the heat energy produced inside an engine’s combustion chambers ends up as waste heat that goes into the block. This heat must be eliminated, otherwise the engine will overheat and self-destruct. The water pump keeps coolant circulating between the engine and radiator to get rid of the heat. The
Subaru Engine Repairs: Attention to Detail Critical in Head Gasket Replacement
To say the first Subaru brought to our shores in 1969 by Malcolm Bricklin was different would be an understatement. The Subaru 360 was a shrunken version of a VW bug, with a small two-cycle engine in the back. It fit into a market niche that probably didn’t exist at the time in the U.S.;
Selling Services: Providing Manual Transmission Clutch Replacement Service
Because a good “stick shift” driver can always squeeze a few more miles per gallon out of a manual transmission or otherwise out-perform their automatic transmission counterparts, it’s no wonder that clutch replacements continue to be a good business for repair shops. In most cases, a routine clutch replacement requires very little in special tooling
Diagnostic Dilemmas: The Pressures of Intake Manifold Vacuum Tests
Several years ago, a retired school teacher brought in a 1994 Chevrolet S-10 Blazer that had developed an intermittent rough idle condition. Although a rebuilt engine had been installed a year before, and all of the wiring and vacuum hoses looked as if they were in factory condition, I took nothing for granted. An ignition
