The Chevrolet Tahoe nameplate was introduced in 1995, replacing the full-size Chevrolet Blazer name. The Blazer became solely an S-10 smaller series truck from 1995 onward. The 1995 Chevrolet Tahoe was equipped with a 5.7-liter V-8 engine, commonly known as a "350." The Tahoe produced 200 horsepower and 310 foot-pounds of torque and was available in both two- and four-wheel-drive versions. Replacing the Tahoe's spark plugs will increase the spark and ignite the fuel better. Higher fuel ignition can increase fuel mileage and engine performance.
Instructions
- 1
Open the Tahoe's hood and set the prop. Disconnect the negative battery cable from the battery using an open-end wrench.
2Remove the spark plug wire from one of the spark plugs using boot puller pliers or standard pliers on the boot. Do not pull the wire itself, as this can ruin the wire ends. Twist the boot of the wire and pull it off the spark plug.
3Remove the spark plug with a ratchet, a spark plug socket and an extension. Turn the spark plug counterclockwise until it is thoroughly loose and easy to rotate. Disconnect your ratchet from the spark plug socket and extension. Rotate the spark plug completely out of the engine using the socket and extension.
4Set the spark plug gap on the new spark plug to 0.035 inches using a spark plug gap tool or feeler gauge set. Some spark plugs do not have an adjustable gap, so read the packaging carefully before trying to adjust the gap size. If you have non-adjustable plugs and the gap is wrong, take them back to your parts supplier and get plugs with the exact gap your truck needs.
5Install the new spark plug into the spark plug socket, with the threaded end protruding out of the socket. Use your socket and extension to turn the spark plug into the engine a few threads to ensure proper threading of the plug. Tighten the plug to 11 foot-pounds using a 1/2-inch-drive torque wrench, socket adapter, spark plug socket and extension.
6Apply a small portion of dielectric grease into the spark plug hole, in the end of the spark plug wire. Install the spark plug wire onto the plug and push the wire into the plug until it clicks and locks into place. Push only on the boot of the wire and not the wire itself.
7Repeat steps 2 through 6 to replace the remaining spark plugs. Use different-length ratchet extensions and a U-joint swivel socket to access the plugs, based on the room you have in the engine compartment. Connect the negative battery cable when all of the plugs have been replaced and the spark plug wires have all been set. Tighten the battery cable snug with an open-end wrench.
