  Q: How to service and repair the timing chain tensioner on Ford Freestar?

  A: Service of the timing chain tensioner requires positioning the vehicle on a hoist with NEUTRAL setting then removing the engine front cover. You must detach the synchronizer drive gear after unbolt ing it followed by removing the actual gear. Align the marks and keyways on the crankshaft before compressing the timing chain tensioner and putting in a retaining pin to keep it compressed. Service the timing chain tensioner by removing first the camshaft gear together with crankshaft gear and timing chain assembly and then all the bolts and the tensioner itself. The installation process requires fitting the timing chain tensioner along with its bolts before torquing them to 11 Nm (8 ft lbs.). Set the tensioner pad mechanism aside before putting in a retaining pin. Start by rotating the crankshaft to No. 1 piston TDC with the key at the 12 o'clock mark followed by manually adjusting the camshaft gear to position the balance shaft at its lowest point. Line up the timing marks alongside the keyways before taking out the retaining pin by mounting the timing chain assembly consisting of crankshaft gear and camshaft gear. Seal the engine front cover in place after tightening the synchronizer drive gear and bolt to 45 Nm (33 ft. lbs.).
