First you are going to need to take out the number one plug to find TDC (top dead center). To find TDC, you will need to either place a piece of electrical tape over the hole where the #1 plug was or have a helper place their finger over the hole. After that you will need to turn the engine over very gently or in quick bursts until the tape is blown off or your helper feels a quick burst of air from the whole. to wnsure you have TDC, try it a couple of times until you find the exact point where the piston is in its highest position. Once you have found TDC, you can replace the distributor. Make sure that when the distributor is going in you will need to offset the rotor button so it will line up with the #1 plug wire. You may have to try it a couple of times until you get it right. If the distributor does not go all the way down then the oil pump is not lining up. No worries, while the distributor is in and lined up slowly turn the crank until it drops nicely into its place. bolt it up and fire it up. you should be set at this point. Get a timing light and check just to make sure. You can tell if the timing is set right by the sound of the engine.
On the Vortec the computer does it all.
how do you set the timing on a distriubtor for a 2002 Chevy blazer
Answer timing 95 4.3 vortec Chevy blazerTiming is non adjustable, period. The high voltage switch ( or known as the distributor) is pinned into lower intake and cannot be moved. The timing is controled by the computer.
look at the manual
The 4.3L V6 GM engine does not have a timing belt it has a chain, and it does not directly drive the distributor.
the 1996 s-10 blazer 4.3 vortec has the computer in the engine compartment on the left hand side....if this is true, you cannot, I repeat, cannot adjust the timing.....the computer adjust the timing....you should be able to read it on the sticker under the hood..... ------- The timing is computer controlled - no way to adjust it, the computer does all of that for you.
set to zero degrees base timingthe computer controls actual timing
what year? popping like a backfire through the intake? check the timing if it has a distributor.
No it will not , The timing is Electronically Controlled, NOT ADJUSTABLE.
There is no ajustment for the timing on vortec engines the computor does it automaticly
It is electronic controlled and requires an OBDII engine scanner to set the timing if it has a distributor. If it don't have 1 then there is NO adjustment for the timing. You did not give the engine size.
No, and you need the flywheel if you expect the car to move. Timing is adjusted in the distributor, not by the flywheel.
There is no more timing marks for a 98 vortec you have to go off marks on distribitor & use a scanner. You are setting cam timing
Short Answer: it is not supposed to change. The actual timing is determined by the ECM using input from several sensors including the CKP and the CMP.
1996 and later 4.3 liter Vortec's timing can not be adjusted. The timing is controlled by the computer
There is no timing adjustment on that year. Computer controls the timing. This is partially correct. The distributor can and has to be adjusted to set the cam retard offset. For this you will need a scan tool that does this.
It should be 6 degrees before tdc, just make sure you disconnect the distributor's computer control wiring harness before you adjust, and check the timing with a timing gun.
The only thing you can do is set the basic timing by ear good enough to get it running If you just put the distributor in the engine. The timing is not ajustable it is controled by the computor. It requires an engine scanner to set the timing, not a timing light.
you face your distributor to your number 1 which should be the driver front plug.get it to where it starts, then you have to get it timed through your computer at a shop.
The timing on that engine is controled by the computer. You can not use a timing light. The only thing you can do is move the distributor enough to get the engine to run and have power and that is called the base timing. When it does run and the engine light is not on then you got lucky, but if the check engine light comes on, then you will have to get an engine scanner and hook it up and go into the timing mode and move the distributor until you get the cam and crank in time. The scanner will show you when it is in time and the engine light will go off. Tighten distributor and your done. The computer will do the rest.
It is bolted to the side of the timing cover right behind the harmonic balancer. That is the bottom pulley on the front of the engine.
Timing is set by the PCM and is not adjustable.

The 96 Chevy Blazer does not have a timing belt.
