Supercharger Replacement

Supercharger Replacement

Removal Procedure

Caution: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.

Notice: Servicing of the supercharger unit itself is limited to replacement only. No attempt should be made to disassemble the supercharger, as parts damage may result.

Caution: Refer to Battery Disconnect Caution in Service Precautions.
