How do you set the engine timing on 300zx v6 twin cam?

Answer 1

First : you need a timing light. you can get one at Walmart. $30

You need to remove the radiator shroud and fan!

so you have a clear view at the crank pully ! see the marks on it .

Next hook the timing light to the Pos. on the battery, then clamp the other wire to the looped wire on the ptu wire harness on the pass. side timing cover. That is your cyl.1 firing.

On the drivers side timing cover is the crank sensor. loosen the three bolt (don't remove them) that hold it in place. you can now adjust your timing by turning left or right one mm at a time. MAX is 15 deg. min. 10deg.

Start your engine run at idle . Point timing light at crank. take reading and make adjustments to the crank sensor by turning it left or right. DO NOT GO MORE THEN 15 deg.

The answer above mine is absolutly correct, I deleted that other answer that made no sense. BUT save yourself the time by leaving your radiator shroud and fan alone. Get a small Phillips head screwdriver and unscrew, yes you can still reach the bolts with the little screwdriver or better yet, a 10mm socket and rachet. Then go ahead and do your timing the way he explained.

If anyone says different about you having to remove the shroud and fan eithier don't know or chooses the hard way. The little screwdriver is also known as a stubby screwdriver or 3" screwdriver
