  Q: How to service and repair the timing belt on Mercury Villager?

  A:

  The maintenance process for the timing belt begins with draining the engine cooling system followed by removing bolts from the crankshaft pulley and water pump pulley. The next step of servicing the timing belt requires removing the six bolts from the lower timing belt cover followed by lowering the vehicle. Begin by unclipping the clamps above the Radiator Hose and removing the bolt before moving to detach the coolant bypass hose that needs its clamps to be released. Dispose the A/C compressor idler pulley and bracket through bolt removal before placing wire harnesses to the side after unclipping them. First disconnect the vacuum reservoir vacuum hose and unclip the main wire harness before repositioning it and unclip another wire harness to place it aside. Start by releasing the clamps of the spark plug wire and removing the bolt before taking out the positive crankcase ventilation breather hoses and tubing followed by removing the bolt. The timing belt covers require removal through separation of seven upper and seven lower cover bolts. The mechanic first positions the number 1 piston at Top Dead Center (TDC) of its compression stroke then removes the timing belt guide and belt through nut and tension loosening. Before placing the new timing belt be certain to position the arrow toward the opposite direction of the engine along with precise alignment of the three white timing marks with their respective camshaft and crankshaft timing marks. The timing marks on the left and right camshaft sprockets should have 40 teeth separation while the left camshaft sprocket and crankshaft sprocket should have 43 teeth separation. Check that the camshaft timing marks located on the seal plate match the crankshaft sprocket timing mark while it points to the oil pump timing mark. First, begin belt installation at the crankshaft sprocket before moving it in a counterclockwise direction to attach to the camshaft sprockets with no looseness in the belt. Install the timing belt on the tensioner after proper timing mark alignment then raise the vehicle before installing the crankshaft pulley bolt. To properly set piston number one at TDC the technician must rotate the tensioner clockwise then counterclockwise twice before locking the nut and manually moving the crankshaft two full rotations clockwise. Press the timing belt in its center point then measure the amount of deflection that results between both camshaft sprockets. Start by removing the crankshaft pulley bolt then lower the vehicle before installing the outer timing belt guide followed by the upper timing belt cover through bolt installation of its seven components. Join all PCV breather tubes and tubes to their clamps before installing the securing bolt. First reinstall the wire harness bracket and then put on the spark plug wire followed by connection of the main wire harness. Follow these steps to attach the vacuum reservoir vacuum hose while the technician returns the wire harness back before they mount both the A/C compressor idler pulley and bracket using their bolts. Bypass the coolant hose and secure its clamps while connecting the upper hose and positioning both clamps before installing the bolt. You should raise the vehicle for installing the six lower timing belt cover bolts followed by the water pump pulley and crankshaft pulley. Fill the complete engine cooling system as the last step.
