GP214S STAINLESS HEADER FORD F150 TRUCK 4.2L 2/4WD WITH EGR FITTING HAS 02 SENSOR 2/ 2 Thank you very much for purchasing our Gibson header for your vehicle. If you need further assistance, please do not hesitate to call our Technical Department at (800) 528-3044 Monday through Friday 8:00 a.m. to 5:00 p.m. PST.
WHEN THESE INSTRUCTIONS ARE FOLLOWED PRECISELY, YOU WILL FIND THE INSTALLATION OF YOUR EXHAUST SYSTEM TO BE RELATIVELY SIMPLE. WE CANNOT OVER EMPHASIZE THE IMPORTANCE OF ADHERING STRICTLY TO THIS PROVEN APPROACH, AS IT WILL VIRTUALLY ELIMINATE ANY DIFFICULTIES, WHICH YOU MIGHT OTHERWISE ENCOUNTER. DUE TO RESTRICTED ROOM IN THE ENGINE COMPARTMENT, YOUR HEADERS MAY COME CLOSE TO CERTAIN BODY AND CHASSIS COMPONENTS. THIS IS A NORMAL CONDITION FOR AN INSTALLATION OF THIS TYPE.
WARNING! – Do not rely on bumper jacks or chassis jacks for support during header installation. The subject vehicle should be raised and supported with jacking equipment and jack stands or ramps intended for undercarriage auto maintenance. It is extremely dangerous to work under an improperly raised and/or supported vehicle. WARNING! - Make certain there is ample clearance around components such as brake lines; brake proportioning valves, fuel lines, hoses and pumps, and electrical components and wires.
CAUTION! Gloves or other protection should be worn to protect installer from burns due to hot exhaust components during these final steps! IT IS CRITICAL that all bolts be re-tightened HOT after about 20 minutes of operation to prevent gasket failure. NOTE: HEADERS ARE NOT MEANT TO SERVE AS “EXHAUST SYSTEM SUPPORT HANGERS”. Additional hangers may need to be added at the time of the installation of the headers so that THE EXHAUST SYSTEM SUPPORTS ITSELF when the collector bolts are removed.
INSTALLATION INSTRUCTIONS NOTE: INSTALLATION OF THESE HEADERS REQUIRES AN ADEQUATE WORK SPACE, GENERAL MECHANIC'S TOOLS, GENERAL MECHANIC "KNOW-HOW" AND A REASONABLE DEGREE OF EXPERIENCE. 1. PLACE VEHICLE IN A LOCATION WHERE THE FLOOR IS SOLID AND FLAT, WITH ADEQUATE LIGHTING. DO NOT ATTEMPT TO WORK ON A HOT ENGINE. HEAT CAUSES METAL TO EXPAND AND MAKES REMOVAL OF FASTENERS DIFFICULT. 2. REMOVE POSITIVE BATTERY CABLE FOR INSTALLATION. NOW JACK UP THE VEHICLE USING A FLOOR JACK AND JACKSTANDS.
