If you have gotten into a front-end collision or would like to upgrade your hood to one that is lighter or one that has a hood scoop, you will need to replace your hood. Replacing the hood seems like a task for a body shop but is actually one of the simplest things you can do on your vehicle if you have a helper to give you a hand.
The hood (US & Canada) or bonnet (most Commonwealth countries) is the hinged cover over the engine of motor vehicles that allows access to the engine compartment for maintenance and repair. In British terminology, hood refers to a fabric cover over the passenger compartment of the car (known as the 'top' in the US). In many motor vehicles built in the 1930s and 1940s, the resemblance to an actual hood or bonnet is clear when open and viewed head-on; in modern vehicles it continues to serve the same purpose but no longer resembles a head covering.
On passenger cars, a hood may be held down by a concealed latch. On race cars or cars with aftermarket hoods (that do not use the factory latch system) the hood may be held down by hood pins. A hood may sometimes contain a hood ornament, hood scoop, power bulge, and/or wiper jets. Hoods are typically made out of steel, but aluminium is rapidly gaining popularity with auto companies. Aftermarket manufacturers may construct hoods out of fiberglass, carbon fiber, or dry carbon.
1. Open the hood and prop.
2.Instruct your helper to go to one side of the hood while you remain on the other.
3.Use an appropriately sized ratchet to loosen the two bolts at the base of the hood where it attaches to the hinges that allow it to move up and down.
4.Give your helper the ratchet that you were using and instruct him/her to remove the other two bolts holding the hood. Make sure to hold the hood firmly while your helper is removing the final two bolts.
5.Grasp the hood firmly and pull the prop rod out of the hood.
6.Remove the hood from the hinges and place it out of your work area.
7.Install the new hood on the hinges and prop it with the prop rod.
8. Tighten all four bolts with a ratchet.
9. Close the hood.
In Japan and Europe, regulations have come into effect in recent years that place a limit on the severity of pedestrian head injury when struck by a motor vehicle. This is leading to more advanced hood designs, as evidenced by multi-cone hood inner panel designs as found on the Mazda RX-8 and other vehicles. Other changes are being made to use the hood as an active structure and push its surface several cm away from the hard motor components during a pedestrian crash. This may be achieved by mechanical (spring force) or pyrotechnic devices.
