Heat Shield Instructions
Protect your wood bed from the heat of the exhaust pipes by installing a
Mar-K exhaust heat shield available in stainless steel or electrogalvanized
steel. One or two may be used depending on what exhaust system the truck
may have. The heat shield protects the wood where the exhaust pipe or
pipes bend up and over the rear axle housing and come close to the wood floor.
- Place the exhaust heat shield directly over the pipe at the point where
the pipe comes closest to the wood boards bottom surface. It may fit
on one individual board or may need to fit onto two boards side by side.
Place the heat shield with the open area pointing towards the front and rear
of the truck so that air may flow under it between the wood and heat shield.
- Mark the wood board or boards through the exhaust heat shields holes.
Make sure that the hole locations are greater than 3/4" from the edge of any
of the wood boards. Any closer than this and you may drill into a bed
strip groove which will not be the full board thickness.
- Drill at the marked locations with a 1/8" drill bit. The holes
should not be more than 3/8" deep. Use a drill stop if necessary to
prevent drilling completely through the wood board.
- If using the electro-galvanized heat shields, paint them before
installing. If using the stainless steel heat shields, remove the
protective tape from the surface.
- Install the heat shield with screws provided. As you install these
screws, you may wish to seal the holes in the wood with a wood sealer or
some water-tight sealer to prevent the wood from rotting.
