The plugs are accessible from the top of the engine, there is an individual coil pack over top of each spark plug (they are kinda egg shaped and they have a little heat sink in them) just pull these out and below you will find the spark plug. you may have to remove the air intake to gain access to them.

Where are my spark plugs located in my 02 Gmc envoy?

Attached is a diagram of where the plugs and coilpacks are located, you need to remove the air intake resonator box to access this area. Plugs should be changed around 100K miles. Use only AC Delco 41-103 Iridium plugs. #1 is the coilpack and #5 is the spark plug

Where are the spark plugs located on a 2004 GMC Envoy?

Assuming you have the 6 cyl. engine, the plugs are located under the airbox (the black box with Vortex on it). Each coil pack must be removed to get access to the plug (see figure below). Be very careful in removing the bolt holding the coil pack.

How do i change spark plugs on my envoy?

If you have a 4.2 L engine, Remove the 10mm bolts on the coils, on top of the engine, remove the electrical connector then the coil, your truck has individual coils, spark plugs are in the hole, 5/8 spark plug socket, don't buy cheap spark pluggs for this truck, it will miss fire, I prefer autolites Autolite Xp Iridium/Spark Plug

Where are the spark plugs located on a 4.3 2004 gmc envoy

Under the plastic resinator on the top of the engine. Remove this along with the hoses connected to it. When removed, you'll see the tops of 6 coils. Remove one at a time (2 screws) and lift straight up and out. I reccommend using AC Delco 41-103's for spark plugs, our engines love these and will idle better. When replacing the coils on top of the new plugs, make sure and either listen to or feel the little click. It's very easy not to get them seated correctly, which will cause an easy misfire and check engine light.

Where are the spark plugs located in a 2004 GMC Envoy, 6 cyl

Hello erikkaloves,

The spark plugs are under the coils. To get to them you must remove the plastic cowling from the top of the engine. Then you will see the coils, there will be six coils, one for each cylinder each looks the same with an aluminum heat sink on the top. These are removed by removing and the retaining the screw and wires.

Once removed the spark plugs can be access but before you remove the spark plugs make sure the spark plug well is clear of foreign material. Dirt or debris in the spark plug well can fall into the engine and cause damage.

I cant find the spark plugs on my 2004 gmc envoy

Assuming you are talking about the 6 cylinder engine, the spark plugs are under a cover on top of the engine. There is a coil pack on top of each spark plug, the plugs are recessed in the valve cover.

Coolant Temp Sensor

The sensor is located on the drivers side engine block...although you can see if from looking from the top of the engine, you would have to get under the vehicle and look up to replace it. Be aware that it takes a special tool to unscrew the old one and screw in the replacement.
