Timing belts themselves are relatively inexpensive but can easily cause thousands of dollars of damage if they break while the engine is running. Engines come in two configurations: Interference and ...

The timing belt is a notched rubber belt, sometimes called a Gilmer belt. This belt allows the crankshaft to drive the camshaft, which in turn opens and closes the valves. Without this belt, the ...

Your car's internal combustion engine requires a massive amount of individual parts to make it run. From the tiniest nuts and bolts to hulking crankshafts and engine blocks, modern motors are composed ...

Many modern passenger cars have either a timing belt or a timing chain. Generally speaking, timing belts have the advantage of being quieter and cheaper to produce and replace, while timing chains ...

Do timing chains last longer than timing belts? Historically timing chains were considered to be longer-lasting and more reliable than timing belts, although this is not necessarily the case on more ...

Most modern variable valve-timing (VVT) systems use a cam phaser that rotates the position of each cam­shaft relative to the timing chain. Think of making a record turntable go faster or slower by ...

This collection of cam-related phenomena is intended to take you beyond the degree-it-in and set-the-valve-lash plateau. In concert with what you may already know about camshaft types, selection, and ...

Does a 1.6 petrol 2007 Mazda 3 have a timing chain or cam belt? Does the Fiat 500 Twin Air use a belt or chain? I have a 2015 Fiat 500 Twin Air which has done 33,000 miles. Should I be considering ...

At its most basic level, an engine is an air pump. Internal combustion engines breathe fresh air and expel wasted exhaust gases to make power. Something has to tell those intake and exhaust valves ...

If your vehicle uses a timing belt and you’re due for a replacement, don’t ever ask to see the old belt — it’ll look perfect, pristine, and as good as the new one that just went into your engine. In ...

For your engine to start, there has to be a perfect timing for every part, especially the engine valves. Depending on the car model, other parts have to move at the same time for the engine to start.
