In an effort to reduce engine noise Cadillac has added a shroud under the engine and revised the one over the top of the engine. Both of these need to be removed in order to access the filter on top and the drain plug below.
From under the hood, unscrew the oil filler cap and then wiggle the shroud – you will notice something is holding the left side intact. Pull the left side straight up about 2 inches to release. Next slide the top shroud forward until it clears the strut tower cross brace. The picture shows it upside down, the two lugs on the rear are visible at the bottom of the picture as is the conical seat in the upper left for the latch, and the oil filler hole on the right.
At this point you might want to replace the filler cap in case you drop a socket. This should take all of 60 seconds to do.
The bottom shroud is held by three push pins accessed from the front bumper and four screws (two each side) accessed from behind each front tire. The screws are shown in the picture for a visual aid, but they are not captive and will fall when released. Remove all 4 screws using a 10 mm nut driver – the shroud will not drop as there are two plastic clips (the rectangular holes between the two screws) that will hold the weight of the shroud.
Reaching under the front bumper, wiggle the shroud and you will see that there are three push pins holding the shroud as is shown by the arrows on the silver duct tape. Only remove these as there are other push pins for other components. The push pins have two slots, one under the head and one between the pin and the shroud. Rotate the push pin until you can see the one under the head. Using a small flat bladed screwdriver, gently twist the blade until the head pulls away enough to grab it and then pull down. The head will pop out about a half inch (or all the way if you pull hard enough) and then remove the body. These are reusable if you pull the head straight out of the body.
To reassemble, I slid a 12-pack box under the shroud, installed the screws hand tight and then slid in the push pins. I went back and tightened the 4 screws using a nut driver. Removal was about 10 minutes to do this the first time, but the next time I could have all the shrouds removed in less than 5. Putting it back together took 2 minutes. Best part is that you do not have to jack up the car to do this.
Here are a couple pictures with the engine top shroud removed. The picture with the element visible is resting on the housing, the other picture show it fully installed.
If you can change your own oil, removing the shroud isn’t that hard; understanding how to get the push pins apart was my biggest challenge. Good luck!
