Question about 1994 Chevrolet S-10 Blazer
Your going to need a spark plug socket with a swivel, extension, and a spark plug wire pliers. You can access the spark plugs through the wheel well. you can from the top but that takes too long and you can't get to all of them from there. You can raise the front end just enough to give you some room in the wheel well with out removing the front wheels. To get to the spark plugs, move the wheel well splash guard up and out of the way so you can access the spark plugs on the side of the engine. One the passenger side is the easy one to work out and should take you under 20 min to do all three, change them one at a time so you don't mix the spark plug wires. On the drivers side is work on the #1plug (towards the front) and #5 (towards the fire wall) first and do #3 plug last. Spark plug #3 is behind the shock tower mount, you need to loosen it first with the socket, then remove the socket and remove and install the plugs by had. It should take you almost 10 min just to do that plug and a cramped hand. When replacing the spark plugs, use anti seize so it's easier to remove the plugs next time and use platinum plugs so your good to go for 100,000 miles unless you have a plug failure due to running too lean or rich. Bring the truck down and place the ignition to the run position for 30 seconds and turn off for 10 seconds and then start and let idle for 1 min then go for a test drive to reset all the engine management sensors. Good luck and hope this helps. Keep me posted, be glad to help.
