Today we are going to install a bug shield on a 2002 Chevy Trailblazer and we are going to be using part number 321251 bug shield accessory for your vehicle. And now we will get started on showing you how it gets installed. Once you have your hood open, the first thing you want to do with your bug shield is go ahead and put it up there and give it a good test fit. Get a feel for how it is going to mount up, find the locations of the mounting holes, and get a good idea of what is going on. Once you figure out how the bug shield is going to install, go ahead and install the hardware. We will show you how that works next. Once you have the hardware installed on the hood we will loosely attach our bug shield. The hardware will just simply screw into the plastic blocks in the hood. Once we have our bug shield loosely installed, we will lower the hood and slide it back and forth in a way where it is centered on the hood the way you want it.
Once you have it the way you want it, carefully lift it back up and go ahead and snug up the screws. Once you get the bug shield tightened up, go ahead and close it, latch it, and make sure the latch operates like it is supposed to. Then check for its alignment one more time if not, go ahead and loosen it back up and re-adjust it until you get it the way you want it. As you can see this is a real nice product, it enhances the appearance of your vehicle and functionality. With the functionality it will blow dirt, bugs and what not away from your windshield up above and past your vehicle. This product is also available in three different sizes, such as part # 391251 and part # 301251.
