This repair is best left to a professional. Why are you changing the timing chain? This is not required unless the chain is loose or worn. It should last the life of the engine.
remove right tire, unbolt the power steering pump, go underneat unbolt the alternators damper, remove the timing belt tensor, remove the old belt, put the new belt on and repeat the process...
It must be a timing CHAIN because Gates ( they make timing belts etc. ) doesn't list a
timing belt for the 3.3 liter V6 engine in a 2007 Hyundai Sonata
You don't. Most manufacturers make motors with a timing chain that should last the lifetime of a vehicle. Unlike a timing belt which requires replacement.
since you didnt include any info on the car cant give a decent answer. look at the pulley on the bottom middle of your engine. thatll have to be removed along with the harmonic balancer then all you...
Lots of cars and timing chains and lots have timing belts. You need to be more specific if you wish an answer. What car are you considering. Need year, make, and engine size to provide an answer.
