Caring For AGM And Flooded Car Batteries
Faulty battery cables, if loose, corroded, or damaged, can lead to power drainage.
Detecting Misfire And Knock Conditions
Knock sensors are mounted on the block near the base of the cylinder head.
Tech Tip: No Start in Cold Weather Due to No Weep Hole
This condition can be caused by condensation freezing in the muffler assembly.
Chassis Control Modules After Reconnecting Battery
To resolve the issue, fully disconnect the negative lead from the battery terminal.
Differentials And Diagnostics
A differential allows the two connected wheels to spin at different rates.
Domestic Gasoline Engine Oil Specifications
If it’s been more than a year since last oil change, the IOLM will display a reminder message, regardless of mileage.
Inspecting Oil Filters
Cartridge oil filters are easy to inspect, but canister oil filters only give you a limited view.
Do Oxygen Sensors Generate Electricity?
They are made of zirconium oxide, a chemical compound used to form the sensor’s thermal-driven electrochemical fuel cell.
EGR, Secondary Air Injection And Emissions Management
EGR systems put a small amount of inert gas into the combustion chamber to control the temperatures.
Mini Cooper Water Pump Service
The water pump is turned by a metal wheel driven by the crankshaft pulley.
How To Diagnose Slow or Sluggish Oxygen Sensors
When oxygen sensors are tested, manufacturers will introduce small amounts of oil to measure sensitivity.
Balancing Combustion Forces
Visual inspection is critical. Any sign of movement laterally is grounds for replacement.
