I would like to know the firing order of the Nissan Maxima Engine V6? I would also like to know how many turn do I turn the crankshaft so that the engnie is back to the normal firing order?

Thanks You.

It should say on the inside of your hood.

 

To figure out the firing order, look at the distributer cap, the numbers on it and the arrow showing the direction of rotation (I'm pretty sure there is an arrow, if not, disconnect the coil, remove the cap, tap the key and see what diretion it moved)..the order the that the rotor hits the contact points on the wire posts is your firing order..can't happen any other way on a cap & rotor style ignition. Or just check Haynes, Chilton, FSM etc to be sure. I'm not sure what you mean by how many turns to get back to the normal firing order. I'm assuming you removed your distributor. In that case to get it back to #1 at TDC, remove the spark plug from #1 cyl (1st cyl on right side if looking at the engine from the crank pulley side, I think), put a long scewdriver in the hole gently, turn the crank until the screwdriver moves vertically up then starts down..TDC is there. Now, is it TDC w/ both valves closed (compression stroke, where ignition occurs) or is it the top of the exhaust stroke? Look at the crank pulley and the timing marks. The crank goes around once for every 2 revolutions of the cam(s). The timing marks should be at the pointer, screwdriver as far out vertically as it will go. I hope this helps. I am not 100% sure about all of this, but since I don't have a manual in front of me, this would be how I approach it.

 

Oh yeah, it should say on the inside of your hood too, forgot about that.

 

Someone correct me if I'm wrong. The Firing order is incremental 1-2-3-4-5-6. The firewall side being 1 3 5 and the other 2 4 6. Say you have cylinder 1 at TDC, a 360 degree rotation of the crankshaft will set the stroke to either TDC exhaust stroke or TDC compression stroke. So if you want it do a full cycle you need to turn the crankshaft 2 full rotations. A sure way to tell is if you take the distributor cap off and look at it as it rotates. A full rotation at the crankshaft should move the distributor end 180 degrees.

 

Right on..it's 123456 like you said. Look at the cap and that's the order of the wire posts..put #1 at TDC compression and that's what you get. Yes, the crank goes around twice for a complete cycle, the cam 4 times and the dist rotor once. Correct me if I'm wrong.

 

The cam will only turn one revolution also. Each valve will open/close once for each two crankshaft revolutions. Remember the size difference of the crank timing belt pulley versus the camshaft pulley? Camshaft is twice the size of the crank pulley = 1/2 the speed.

4-cycle = intake->compression->power->exhaust. First two cycles = crank revolution #1 and last two cycles = crank revolution #2.

Thanks for the correction..all makes sense now..2 crank rotations= 1 cam rotation. Got it.

 

Thanks everybody
