Installation

Install video is located HERE.

Start by removing the engine bay cover from the car. Remove the rubber seals and the metal hinges from the engine cover using a 10mm socket.  Fill the 4 bolt holes with the rubber plugs provided in the installation kit. Before proceeding or removing the VHB adhesive tape backing, place the seals on the open holes to get a sense of placement and positioning. Do not place the oil cover too close to the back of the hole/center of the car - use the outside edge and place just inside the lip - this will prevent the back of the Fast Access Cover it from rubbing on the engine bay cover.

Use the alcohol preps to thoroughly clean the mounting area around the coolant and oil seal holes.  Allow to dry 1 minute. Once dry, apply adhesion promoter to the mounting area around the perimeter of the coolant and oil seal holes. Allow to dry 1 minute.  Remove the VHB acrylic tape backing and center the covers over the holes, pressing down firmly.  Lift the top bezel off to expose the black mounting ring. Press down on the black mounting ring down all the way around to ensure good adhesion and full contact is made. Reinstall the engine bay cover. Snap on your new C8 Corvette HTC Fast Access Covers and head to your nearest car show!

IMPORTANT INSTALLATION AND USE WARNING:  Do not use glass cleaner, alcohol or other chemicals on the acrylic windows. Remove the covers if removing the engine bay cover and when washing the engine bay to avoid damage and clean with a soft detailing cloth.  Do not wipe when dry to scratches - always use Novus or another acrylic safe eyeglasses cleaning product that is alcohol free.
