How do you change the timing chain for suzuki grand vitara 2002?

Hi there,,,,first of all, be careful buying the spare parts because I bough one timing set from the internete, replace the old one and had to put the old one again back.The new one was desintegrating inside the engine...unless it said is made in Japan do not even tink about replacing the old one with an aftermarket one.

....You have to take the fan out, the radiator water pump pulley, idle polleys ( both) , the a/c copressor, the a/c compressor braket and finally the crank shaft pulley which need an air tool to take the mail bolt aout.

after that take the ignition colis out and the spark plogs too , the valve cover and the timing cover.Use a rag to cover the oil pan seccion which is exposed to debris getting inside. Aling the marks in the crank shaft sproket an te one tha is in each camshaft , then retire the upper chain , tensioners and sprokers , then the lower chain and the intermediate sproker, begin reasambling in the reverse order ...then rotate clockwise one or twwo revolution in order to check the marks coincide again and procede to reasambling every part in the reverse order

you must to clean the valve cover, the gasket and the timing chain cover, replace the crankshaft seal and use a litle bit grey silicone to make the gaskets
