How do you remove the spark plug boots on a 2000 Alero (2.4L)
I saw some links describing how to remove the cover plate on the Alero to get to the spark plugs. I did that without issue, but I can't seem to get the spark plug boots off. There is a plasic housing at the base that looks to hold the boot in place. I twisted the housing to free the tabs on the boot, but when I pul on the boot it still does not seem to be coming off.
Re: How do you remove the spark plug boots on a 2000...
All i did to remove the plug boots is used a long pair of needle nose pliers. Just be careful not to damage the boot. I recommend a twist and up and down movement when pulling and it will pop off. Dont forget to put some plug lube on when you replace the boots on the plugs

THE COILS ARE BOLTED TO THE VALVE COVER BY ONE 8MM HEAD MACHINE SCREW, REMOVE IT AND SLOWLY TWIST THE COIL BACK AND FORTH TO FREE UP THE RUBBER SPARK PLUG BOOT ON THE COIL FROM THE SPARK PLUG WHILE APPLING UPWARD PULL. AFTER THE COIL (DO ONE AT A TIME) IS REMOVED THE PLUG USES IS A 5/8" SPARK PLUG SOCKET TO REMOVE, YOU WILL NEED AN EXTENSION.
if the engine says its a 2.4. then it is a 4 cylinder ( 4 plugs ).on the 2.4 remove the four bolts on the ignition coil cover. pull the idi cover straight up until the boots are off the spark plugs, then set cover aside. if the boots stick to plugs, you can reatach them to coil cover on bottom of idi cover. thats it !! have a good day !!
On the top of the engine there should be a silver looking plate with a electrical connector on the driver side. Remove the connector, remove the 4 10mm bolts, gently pull up and wiggle at the same time, there are boots that connect to the top of the spark-plugs. put the boots on the plate when you put it back together. This procedure applies to the 2.2L 4 cylinder engine
To gain access to the spark plugs and spark plug wires do the following. In a 2.4 liter engine, remove the ignition coil and module assembly from the top of the engine to gain access. In this Alero model's engine, the spark plugs run down the center of the engine. In a 3.1 liter engine, remove the air cleaner to gain access. The spark plugs are located next to the engine oil reservoir. For a 3.4 liter engine, remove the windshield wiper module cover and rotate the engine for service access. For a 2.2 liter engine, the spark plug wires are located across the top of the engine and require no components to be removed for access to the spark plugs.
your car has an unusual ignition set up, it's all located in the top cover,no plug wires, just plug boots. unless you are having a missfire or other drivability problems,just repace the spark plugs, fuel filter and air filter
There are no spark plug wires on the 2000-up Northstar engines. They use coil on plug design. First remove the engine service cover.(The Pretty plastic peice that has the Cadillac symbol on it) Then disconnect the coil connector which sits to the right of the coil and should just snap off by hand. Next If you remove the screws that holds the coil pack (8 screws) to the top of the cam covers, you will see 4 black round rubber boots that sit on top of the plugs. Pull the boots free to expose the plugs. The tops of the spark plugs sit directly underneath
IF YOU GOT A 3.1 OR 3.4 ENGINE.LOCATE ALTERNATOR.THEN GO TO RIGHT.SEE A COIL PACK WITH 6 SPARK WIRES ON TOP FOLLOW WIRES .TO YOU SEE PLUG BOOTS.SPARK PLUGS IS UNDER THE BOOTS.YOU NEED A 5/8 SPARK PLUG SOCKET.3/8 RACHET WRENCH WITH 3 INCH EXTENSION OR 6 TO 10 INCHES.YOU NEED ALSO NEED PLUG WIRE BOOT REMOVER TOOL.AND A SPARK PLUG GAP GAUGE. NOW IF YOU GOT THE 2.4 ENGINE YOU HAVE TO REMOVE THE TOP PLATE COVER.ITS THE WHOLE COVER ON THE INTAKE.IT HAS 4 SCREWS THAT HOLDS IT IN PLACE .YOUR SPARK PLUGS IS UNDER PLATE.
