Installing a new hood release cable is not very difficult. It is very important to look at the routing of the cable. The cable is just long enough to be installed in its original position and does not leave much slack for deviations. It starts at the hood latch and travels under the top radiator support and through a hole near the driver’s-side head light. It goes from there along the driver’s-side fender well, usually under the air cleaner or whatever is located on the fender well, which varies from one car to another. In all cases, it covers the same path. A close look will reveal its location on the fender well. It should be able to be replaced removing very few items, if anything. It then goes down through the firewall right below the brake power booster. This location on many vehicles is difficult to see, but can always be felt.
Lift the hood. Remove the hood release cable at the hood latch using the needle-nose pliers.
