Honda: Engine Shuts Off, Power Remains ‘On’ Or ‘Accessory’
The culprit could be a misadjusted shift cable.
Why Do Modern Vehicles Require Precious Metal Spark Plugs?
Understanding modern ignition systems will help complete preventative engine maintenance during tune-ups.
K-Seal SolvTec Tech Tip: Curing Heater Core Leaks
A classic sign of a heater core problem is when the inside of the vehicle’s windshield persistently keeps misting.
Anchor Industries Tech Tip: Engine Vibration
When engine vibration is noticeable at idle, especially with 4-cylinder, odd-fire V6 and diesel engines, it is most likely a sign that the mounts are worn or completely broken. These vibrations tend to worsen when the A/C compressor is engaged.
Nissan Tech Tip: Abnormal Noise From Front Engine Mount
A two-piece design front engine mount is currently being used for the vehicle applications listed in this Tech Tip. A single thunk noise may be heard during the first few accelerations of the day from this type of mount, and is considered normal operation.
0W16 Versus 0W20 Oil
The big question among shops is how can four points on the viscosity rating change the performance and longevity of the engine? This is data that is difficult to come by, much less evaluate.
More Than Codes: Finding The Story Behind An Emission Code
If you are the kind of technician who solves emission codes by replacing parts and hoping the check engine light does not come back on, this article is not for you. But, if you want to diagnose a emissions-related problem, confirm the fix, and know when the car leaves the shop the job will be completed, this article is for you.
Catalytic Converter Replacement Rules And Regulations
If you are replacing a catalytic converter for a customer, it is not the same as replacing a muffler or pipe. Since the catalytic converter is an emissions device that is federally and locally mandated, documentation is just as key as proper installation.
RETRO 1974: Refilling Catalytic Converters At The Shop
1974 saw the first catalytic converters placed on vehicles and the use of unleaded gas. While Chrysler went with biscuits, GM, Ford and AMC went with beads. The beads were designed to be serviceable. With special tools, the platinum-covered beads could be removed through a hole and replaced with fresh beads if the owner poisoned the converter with leaded gas.
These are the beads that were in the converter. If the converter was damaged internally, the beads might escape out the tail pipe.
VIDEO: Diesel Particulate Filters And Regeneration Cycles
Jason Stahl discusses diesel fuel systems, and the ideal time to perform a regeneration cycle, if the vehicle is able to perform the procedure. Sponsored by Standard.
Diesel Particulate Filter Regeneration: When, Where And Why?
The Diesel Particulate Filter (DPF) is a ceramic brick with tiny passages that do two things. First, they trap the particulates or soot in the exhaust. Second, these passages create the surface area for the precious metal that helps to burn or break down the particulates. Think of it as a catalytic converter that traps and oxidizes particulates in the exhaust. But, the DPF regenerates in intervals rather than all the time like those found on gasoline vehicles.
Wideband Oxygen Sensors Vs. Narrowband: Understanding The Differences
Wideband air/fuel oxygen sensors may appear similar to conventional narrowband oxygen sensors, but there are quite a few differences that you need to be aware of to service vehicles with this new style sensor.
