Distributors and Distributor Caps
Distributors and distributor caps are components of an ignition system. Most internal combustion engines use these to deliver high voltage sparks into the engine in the correct firing order, which in turn creates combustion.

How to set valve timing on 1995 Daewoo Nexia DOHC?
I learned a few things: You can of course (with the head off or by looking at the bottom of the pistons up through the sump) work out the timing (approximately but accurately enough) to see where the marks should be. And where they should be there will be a very obvious timing mark/spike on the engine block or head cover or something or at least a very obvious alignment of marks with each other. You know, when the #1 piston is coming to the top and the inlet is just opening and the exhaust is just about closed then that is the end of the exhaust stroke and then the intake stroke is about to start - well get the crank and the cams about there, then rotate keeping them in sync and you will see what I mean. Put the pully and cams in the right places (approx) before putting the head back on - less likely to bump piston and valve that way. Turn the engine over a number of times (the cam goes clockwise/forwards) by hand - you should only have very slight resistance from the pistons compressing air (so only twice for a rotation of the crankshaft pully). If you get hard resistance that seems to be from the cams when turning the crankshaft you have got the timing wrong - the pistons are bending the valves. Do not do bolts that go into the aluminum head too tight. To get the pully and cover on/off - just crowbar the engine over a bit. Oh yeah - those half moon shaped dents in the top of the pistons - that is to handle the valve overlap.
Hope that all helps
The crankshaft pulley mark on the timing cover is for the drive belt pulley, the mark at 6 o'clock is for the crankshaft cog (behind the pulley),there is a small dot on the crankshaft cog which lines up on the small mark on the small bottom timing cover. When changing the head gasket to prevent damage to the valves turn the crank back to the 3 o'clock position and when the camshafts are lined up (inlet 3 o'clock exhaust 9 o'clock) turn the crankshaft clockwise to 6 o'clock.
What is the firing order for a Chevrolet ZZ4 engine with hei dist?
Knowing the firing order of an engine can help with troubleshooting later. The firing order of a Chevrolet ZZ4 Engine is 1-8-4-3-6-5-7-2.
Correct firing order is 1 3 4 2 Your distributor cap is numbered 4 2 1 3 on the top in a anti-clockwise direction. Match the HT leads from the cap to the corresponding spark plug.Thats it . PW
sounds like you temperature sending unit is bad. very cheap part usually easy to fix however sometimes hard to find - buy an automotive book for you car or ask someone at parts store
What is the order for a 1994 geo prizm 1.6L engine distributor cap?
1. The firing order for the 1.6L is 1-3-4-2.
2. Looking from the front of the car the cylinder order is 1-2-3-4 from left to right.
Your distributor cap will probably have the numbers on the wire location. If not look at the distributor cap from the driver side.
Number 1: Top right
Number 3: Top left
Number 4: Lower left
Number 2: Lower right
It is always recommended to replace one plug wire at a time to prevent connecting in the improper location.

take off the cap...mark were the distributor meets the engin block.....unbolt the two bolts pull out distribotor...when you replace match up marks and turn rotor back or forward a little till shaft slips in...never force any thing/////o remove the wire conected to it..fits only one way....it real easy
What is a distributor cap for a Ford F-150 Lariat?
If your Ford F-150 is a 1996 model or older it has a distributor / distributor
cap . 1997 and newer either have the EDIS ignition system ( Electronic
Distributorless Ignition System ) or the C.O.P. ( Coil On Plug ) ignition system
depending on the engine size and year
Why does your 1986 F-250 6.9 diesel die when it gets warm and won't start until it cools down?
could be that your wires are crossing to your timing advanse fast idle line. check the volts on the fuel shutoff cyliniod on the fuel pump(front one,back one is the timing advance)after it quits. also try leaving the key on pull the fuel shutoff then put it on you will hear it click. if it does not and it has power ,bad cylinoid. or the fuel return lines are plugged. pull the fuel line off the fuel pump stick air at 10psi blow into the line to the tank (not the pump)youshould hear bubles in the tank shortly. if not your lines are plugged or tank changer problems (bypass) . the shutoff cyliniod blocks the return line to shut the engine off (when it has no power)or it doesn"t work
How does battery get charge while running the vehicle?

The engine cylinders are numbered 1 to 6 , from front to rear
What is the difference between a points distributor and an hei distributor?
an hei has a solid state ignition module rather than mechanical points... the hei is capable of much higher coil voltages because there are no points to wear out.....the hei is better in terms of performance and longevity
Why does your distributor cap keep corroding?
Need to buy a GM factory cap,wires, rotor. That will take care of it.
Where is the ignitor module in the distributor of a 93 Mazda 626 4-cylinder?
It is inside the ignition distributor. You have to remove the distributor cap first. Then remove a rotor that carries a metal contact by unscrewing a screw from the rotor. The ignition module is below the rotor. You need to remove 2 screws to remove a cover for the ignition module. The two screws are extremely tight and cannot be removed using a normal screw driver. You probably have to use an impact type of electric drill with reversable (counter clock direction) speeds. I still have been able to remove the two screws myself.
