How to service the thermostat on a 4.2L engine on 2006 Ford F-150?

The first step for servicing the thermostat of a 4.2L engine requires cooling system draining. Remove the thermostat by first releasing the clamp of the upper radiator hose from the water outlet connection then remove the bolts securing the outlet while simultaneously gathering both the gasket and the thermostat. The correct method to prepare sealing surfaces involves using a plastic scraper alongside a metal surface cleaner that follows the product directions for installation of the new thermostat. The thermostat requires proper installation by placing the vent facing at either the 11 o'clock or 1 o'clock position before securing it against the cam. Attach the new coolant outlet connection by tightening the bolts at first to 8 Nm which is equivalent to 71 inch lbs before turning them another 60 degrees. The cooling system receives its proper fluid level by refilling it after reattaching the upper radiator hose and securing its clamp.
