See the Related Links below for "How to replace the spark plug behind the steering shaft." for the walkthrough with pictures.
it is so to do . first remove your 2 front tires (the plugs are way easier to do through to wheel well) take a 3/4 or 19mm that you are not fond of and cut it in half, trust me. take your 5/8 spark plug socket and remove the boot inside of it, trust me. slip the socket on to plug # 5 make sure it goes all the way on, use the box end of the wrench you cut to turn the socket if you cannot get it to start turning grab a pry bar put it between the exhaust manifold and use that to help your half wrench i have done that for about 30 tune-ups never failed me once!
not all sockets are the same length, try one that you can put a wrench on, or a long extension through the wheel well, Snap-On is great for those fancy tools, they have a plug socket 5/8 that is on a ball socket (60 bucks for it!) You will probably have to use a wrench on a socet to crack it and then a very short extension with ratchet or a reducer extension that goes 3/8 to 1/4 so you can use a 1/4 ratchet....HTH
I have a 96 Jimmy with 5 new spark plugs. Number 4 is still right behind that steering shaft! Here are some general tips on changing spark plugs in Vortec engines.
1) get a spark plug boot puller ($10 at Crappy Auto) It will be very handy.
2) Jack the truck and remove the front tire. Pull the rubber splash shield aside, and you should have a good view of at least a couple of the plugs.
3) Use a long extension ($15 @ Sears) and universal adapter ($10 @ Sears) to get the plugs out.
4) Pull the boots and change the plugs one at a time. That is, don't pull all the wires off, take all the plugs out, etc... The plugs can be stubborn to get in, so take 'em one at a time.
5) Plan at least 90 minutes for the job if you have a good deal of experience, more time if you have less. It took me two hours, including 20 minutes or so trying to get by the steering shaft.
6) Have patience, and good luck!
I just ripped into what I thought would be a traditional 30 minute change out of spark plugs. YOWIE...was I wrong. 6 bandaids later and over an hour invested, I have 5 new plugs in and one behind the stearing column. Runs ok right now. As I sit here laughing I wonder how long before I attempt that stuborn plug again.
I read the posting on loosening and then changing to a 1/4" rachet. I don't have room for an adaptor nor a swivel. 2001 Jimmy might win a trip to the dealership.
need a puller to remove the power steering pump pulley, then remove the bolts holding the pump on
You will need a power steering pulley puller. It is designed to remove and install the power steering pulley. If you attempt to remove the pulley without it you will probably damage the pulley or the pump or both.
NO you do not. Just loosen all the bolts up on the bracket that holds the power steering pump and then pull the big bracket back enough to get to that corner bolt. It does not have to be moved very far. You must be working on a vortec.
It is bolted into the passenger side of the engine block BEHIND the starter. You can not see are get to it UNTILL you remove the STARTER.
it is an 8 cylinder
If it has a 350 Vortec engine, then it is on the left bottom side of the timing cover behind the harmonic balancer. If it has the genaration II engine then it is behind the starter. You will need to remove the starter to be able to see it.
By running the vins and serial numbers on the VORTEC engine its self and going to the DMV you might have to pay them $50 but it will give you basically all the information on it! (:
The egr valve on the 1999 vortec v6 is bolted to the intake valve. It is just behind the distributor.
Check your coolant temperature switch first to make sure it is working. Thermostat should be behind the flywheel on the front of the block in the water pump. You have to remove the flywheel to get to it.
You have to remove the engine cylinder heads to get to the lifters on the 5.3.
The knock 1 sensor on a Vortec 4.8 is located on the top of the engine. You will have to remove the intake to gain access to replace it.
USE special wrenches.
135 from front to back located on the drivers side or right.246 front to back located passenger or left.
behind the glovebox
It is hard to see and to get to. But it's right behind the distributor.
Usually found behind/under the glove box or behind the kick panel.
you would need to change the cylinder heads also.See link below
under the plastic cover that says vortec there is a huge aluminum cover called a planum disconnect the hoses to that remove the throttle cable unscrew 5 bolts i think it is remove the planum under that is what u be looking for
It is on the front of the engine, behind the timing cover where the timing chain and gears are. You will have to remove the front of the engine to get to it.It is not in the oil pan were they use to be. It now slides over the front of the crankshaft.
It is behind the engine and you can see it clearly in the middle its got your spark plug wires going to it and it has numbers on it if your looking at your engine from the front its directly in the middle at the back of your motor
Regardless of the block, you have to use Vortec heads to use a Vortec intake.
Lefty loosey, righty tighty.
It is inside of the oil pan. You will have to remove the oil pan to get to it.
