How to Replace Spark Plugs in a Cadillac Escaladeby Editorial Team
The Cadillac Escalade is a luxury SUV produced by the Cadillac Car Company. Spark plugs are the parts inside an engine that produce a spark that catches the gasoline on fire. If a spark plug is faulty or damaged, replacing the spark plug is vital to keeping a Cadillac Escalade in working order.
Pop the hood and look at the engine. The spark plug wires are located on the right and left sides of the engine. If the Cadillac Escalade has a six-cylinder engine, there are three spark plugs on the right side and three spark plugs on the left side. If the SUV has an 8-cylinder engine, there are four spark plugs on either side of the engine. These plugs are located halfway down the engine, slightly lower than the height of the battery. Spark plug wires are generally red with black tips.
Remove the spark plug wire from the end of the spark plug. Grab the tip of the spark plug wire. It is the cushioned part of the spark plug wire attached to the spark plug. Never pull the spark plug wire by the wire itself.
Place the 16 mm socket over the spark plug and attach the wrench. Turn the socket counter-clockwise one to two turns to loosen the spark plug.
Remove the socket from the spark plug and turn the plug with your hand until it comes out of the engine.
Clean the inside of the spark plug wire with the wire brush. Lightly brush away any debris or corrosion inside the tip.
Insert the new spark plug into the engine. Consult the owner's manual for the correct spark plug part number for the year the Escalade was manufactured.
Tighten the spark plug into the slot with your hand. Once it is tight, use the socket and wrench to tighten the spark plug about 1/4 of a turn more.
Replace the spark plug wire and repeat Steps 1 through 7 for the remaining spark plugs. If a spark plug wire is connected to the wrong cylinder, the Escalade will have problems firing, which causes problems with the engine.
