The firing order is 18 43 65 72.
43 2 1
When you lift the engine lid and look at the engine, it should say "Zundfolge" 1432 I believe, all engines for the past 60-70 years have had the firing order embossed or stamped where it is readableon the block, engine case, or cylinder head. My '43 Jeep does, my '70 Ghia does, all other cars do as well.
Where is the oil sending unit located on the 2001 Chevy 43. vortec engine?
the firing order is 1-6-5-4-3-2 #1 cyl is drivers side front of engine follow it to the dist. and go clockwise. this is striaght from the book. it's easy to do.
On my Astro, the firing order is located on the distributor cap- Where each plug wire goes into the cap, there is a number on the cap-find#1 go clockwise for the next number etc. That's your firing order
if your saying your engine is a 4.3 your have a v6 not a v8. even with that I've not seen a Chevy engine with cap in front like a ford or Chrysler product. v8 up until 96 i know for sure are 18436572 I have found that some police package cars with a 4.3 it can be a version of the LT1 motor that does have the distributor in the front. I didn't believe it till I saw one at a police auction. I do not, however, have a firing order for this six banger. I hpoe that this might at least help.
Owners manual, positive.
You don't need a diagram to find spark plugs on this engine. Follow the plug wires and you will find the plugs.
there isn't one.
.43 is the gap
