CVT Maintenance Guide: Extend Transmission Life with These 7 Essential Service Steps The continuously variable transmission (CVT) is a type of automatic transmission. It uses a belt-and-pulley system instead of fixed gears to deliver seamless power. Unlike conventional automatics with discrete gear ratios, the CVT keeps the engine at its most efficient RPM. The pulleys…
Timing Belt vs Timing Chain: The Complete Engine Durability Guide Few decisions in engine maintenance carry the weight of choosing between a timing belt and a timing chain. These two components serve the same fundamental purpose — synchronizing the crankshaft and camshaft rotation so valves open and close at precisely the right moment. But they…
CVT Problems Guide: What to Watch For, How to Diagnose, and When to Walk Away The Continuously Variable Transmission — or CVT — is a type of automatic transmission that uses a belt and pulley system to provide seamless, stepless gear ratios. Unlike traditional automatics with fixed gear sets, a CVT keeps your engine in…
Iridium and platinum spark plugs are the two premium electrode materials dominating modern ignition systems—both are engineered to outlast conventional copper plugs by 3 to 10 times, but they achieve that longevity through fundamentally different metallurgical compromises. The central entity here is the spark plug’s center electrode: a thin wire that must survive millions of…
Spark Plug Gap: The Critical Specification Most Mechanics Overlook Spark plug gap is the precise distance between the center electrode and the ground electrode. It directly controls ignition voltage requirements, flame kernel formation, combustion efficiency, and long-term reliability of the ignition system. In 15 years of dealership and independent shop experience, over 70% of misfires…

Spark plug wires is an ignition system component that transfers high-voltage current from the ignition coil or distributor to the spark plugs by insulated conductive cores, ensuring reliable combustion, reduced misfires, and stable engine performance. In 15 years, over 70% of misfire complaints traced back to aged wires exceeding 12,000 ohms per foot. What are…
Ignition timing is a calibrated engine parameter that triggers spark plug firing by advancing or retarding spark delivery relative to piston position, ensuring optimal combustion efficiency, power output, and emissions compliance. In 15 years, I’ve diagnosed 70% of timing-related failures as misadjusted distributor hold-down bolts (torque spec:18-22 ft-lbs) or worn advance weights—both fixable with a…

Ignition system types is a vehicle electrical control system that converts low-voltage battery power into high-voltage spark by timed electromagnetic induction, ensuring complete combustion, stable idle RPM (650–800), and maximum engine efficiency under load. In 15 years of dealership and independent shop work, over 70% of misfire complaints traced back to ignition architecture limitations—most commonly…
