2009 Ford Taurus X Camshaft Parts Q&A

• Q: What precautions should be taken when removing and replacing the camshaft to prevent engine damage and ensure proper installation on 2009 Ford Taurus X?

  A: The camshaft replacement process requires smoking and open flames to be absent because it poses a significant risk of flammable mixture ignition. Cleanliness procedures should be followed to stop mysterious materials from causing engine breakdowns. After installing the camshafts you should check the valve clearance while maintaining the crankshaft in free wheeling position where the dowel pin points to 9 o'clock. The crankshaft should be rotated counterclockwise to reach the 9 o'clock position. Engine damage can be prevented by setting the camshafts to neutral before removal which requires clean engine oil coating prior to installation. The LH and RH cylinder heads should receive their camshafts with the bearing caps fixed in their native locations then tightened with 10 Nm (89 lb-in) torque using the specified sequence. Validate the engine valve clearance through feeler gauge measurement after installation to confirm technical specifications when new components are involved. Place the Top Dead Center (TDC) on both LH and RH camshafts before putting on the Camshaft Holding Tool to assemble Variable Camshaft Timing (VCT) components by lining the colored links with timing marks. Assemble the secondary timing components while performing a four-step bolt tightening procedure then remove lockpins from the tensioners. Follow the crankshaft clockwise rotation until it reaches TDC (dowel pin at 11 o'clock) before installing the primary timing chain that links with proper timing marks. Put in the LO LH primary timing chain guide before torquing it to 10 Nm (89 lb-in) and put in the primary timing chain tensioner arm and reset it. You should put in the primary tensioner while tightening it to 10 Nm (89 lb-in) until the lockpin becomes removable. All timing marks should be aligned before new VCT housing seals are installed as well as the VCT housing dowels are securely seated before torquing bolts to 10 Nm (89 lb-in). Put Motorcraft High Performance Engine RTV Silicone on the engine front cover sealing locations before you mount the front cover using 3 Nm (27 lb-in) torque while following bolt installation order. Proceed with installing the engine mount bracket and remaining engine front cover bolts through two stages by correctly applying thread sealer to engine mount studs. Put on the crankshaft front seal while fitting the crankshaft pulley and tighten the pulley bolt through four stages. Fitting of accessory drive belt tensioner and power steering pump goes hand in hand with putting any needed new seals into place. Install RTV Silicone to engine front cover-to-cylinder head joints before fitting the RH and LH valve covers and tighten the bolts to 10 Nm (89 lb-in). Follow the installation order of PSP tube bracket, coil-on-plug assemblies and complete electrical connector reconnection. The presence of upper engine failure requires inspecting the intake manifold for metal debris then obtaining a new manifold if needed. To complete the installation wrap up by placing the upper intake manifold then secure all wiring harness retainers with bolts torqued up to 10 Nm (89 lb-in).
