For Camry, undo the front
Bumper to remove it; draw a line around the latch for installation, then take off the plastic shield and remove bolts securing the hood latch to the radiator support. To make the hood latch line up straight or down, undo these holding bolts and take the latch off. Pull the hood cable away from the latch assembly, then gently move the cable retainer end out of its groove on the back of the hood latch. To set up the latch correctly, push the hood closed, adjust it until it holds firmly, and make sure the rubber bumpers press together just right. Raise your vehicle, place jackstands under it, then pull off the front wheel. Take off the lower pad from the fender's bottom edge and the inner fender lining. Step by step: Free the hood cable from the latch by pushing on a small clip holding the cable, then moving the cable away from the fixture. Hook a piece of thin wire to the end of the cable, then remove all cable retainers on both sides of the radiator support and firewall. Take off the driver's door sill cover and kick panel from inside the car. Then, get the driver's knee bolster panel aside, letting the cable end detach from its release lever assembly. Hook the end of the cable up to a piece of thread, then gently move the cable and its attached grommet back into your car's passenger area. Hook the new cable on through a grommet, take off the wire or string from the old cable, and fix it to the new one. After joining the new cable to the wire or string, wind it through the firewall until you find the latch assembly. Put the new cable back in the hood cable handle, folding the cable housing neatly into its spot on the handle's bracket piece. When putting the grommet back into the firewall, push it from the inside of the car with your fingers.
