timing belt or timing chain?
 

I was reading an earlier thread about when to change out the timing belt.

Please excuse my ignorance...I am not a Hyundai owner yet but am seriously
considering the Tucson or Sante Fe. I thought most new cars nowadays used
timing chains, which I heard can last forever.

Thanks for your response.

Re: timing belt or timing chain?
 

To this day, most of the domestics still use a timing chain, and rarely does
one ever think about them. A few of the DOHC engines (like the 3.2L and
3.5L in the Dodge Intrepids of the last dozen or so years) used a timing
belt.

Imports much more frequently have used a belt. It allows (supposedly) for
smoother, quieter operation and better fuel economy for the set-up. But of
course, any belt is a maintenance item, and since many of those engines are
"interference" engines, meaning if the belt breaks, you bend or break some
things in the engine (valves, etc.), you best not forget about it.

Something to ponder when you are deciding which vehicle to buy. (All Santa
Fe engines for sure would have timing belts).

The Mazda 2.3 DOHC engine has a timing chain, which by itself is good.
It also has something called "Variable Valve Timing", which sounds to
me like a failure waiting to happen.

I'd say most domestic V-6 and V-8 engines have timing chains, but most
of the domestic I-4's, which by and large are based on foreign design,
use timing belts.

Not as much of an eminent failure as you might think. Variable Valve Timing
(in different forms) exists in a lot of engines these days. Most
manufacturers either have a form of VVT or are experimenting with it. Some
of the stuff that's being toyed with is quite radical for your basic
internal combustion engine. It's not inconceivable that the camshaft will
become a thing of the past, giving way to the ever-present computer, which
will monitor and adjust valve timing.

My 2006 Sonata with the 2.4L engine has a timing chain, if the web site
is correct. I think the new 3.3L V-6 has a chain also, but I'm less
sure on that one.

So do the new Hyundai engines. Time will tell...

And I will add that I am very pleased with the results. My new
Alantra scoots much better than my Accent ever did. The VVT seems to
broaden the torque curve quite a bit.
