Put the crank shaft at TDC. There is a dot on one of the crank gear teeth. It should be pointing toward the cam gear. Put the cam gear on without the chain. Turn the cam until the hole in the cam gear is pointing toward the crank. In other words, the hole in the cam gear and the dot on the crank gear should be in line. Then simply remove cam gear and apply the chain. The computer does the fine timing. Nothing to adjust.
Timing chains should last the life of the engine and are normally replaced when the engine is rebuilt.
Normally the chain will last the life of the engine and is replaced when the engine is overhauled.
Never, it is designed to last the life of the engine and is normally replaced when the engine is overhauled.

Your 1999 Chevy blazer doesn't have a timing belt.
never needs to be replaced

It don't have a timing chain and if it did it would out last the engine. It should have a timing belt and it should be replaced about 60 thousand miles. Sorry I must disagree with my friend who is very knowledgable. The 3.5 Liter and 3.9 Liter Chevy V6 has a timing chain and not a belt. The chain will last the life of the engine.
That engine has a timing chain and gears and will probley out last the engine. NO need to replace it.
Your question really makes no sense. Normally a timing chain will last the life of the engine as replaced when the engine is rebuilt.
unless there is noise coming from the timing chain, you should never need to replace it.
how much play should a 4.3 Chevy engine timing chain have?
