To do that, take away the passenger’s aspect wheel and tire assembly and splash protect so as to entry the crankshaft pulley. Examine that the white mark on the pulley is in keeping with the pointer on the quilt. If not, flip the crankshaft to line up the marks utilizing a breaker bar, ratchet extension and socket.
If piston #1 is on Top Dead Center, the mark on the front camshaft pulley and the pointer within the higher cowl ought to be aligned as nicely, says Ken Freund in “Honda Pilot, Acura MDX Haynes Restore Guide.” If not, flip the crankshaft pulley yet another revolution. With piston primary set at TDC, take away the drive belt and assist the engine with a ground jack beneath the engine oil pan with a wood block on the jack. To entry the timing belt, take away the higher half of the aspect engine mount bracket, the crankshaft pulley, and the higher, rear and lower timing belt covers.

Remove one of many maintain-down battery bolts and grind the threaded tip right into a conical form, leaving a flat tip on the finish. Use this bolt to carry the timing belt adjuster. Barely above and to the left of this adjuster, you will notice an arm protruding from the again cowl of the timing belt. Screw the bolt by hand by way of the outlet on the finish of this arm till the tip rests towards the belt adjuster to maintain it from transferring.
With the adjuster secured in place, you may take away the timing belt information plate, the lower aspect engine mount bracket, the loafer pulley and the timing belt. Ensure the crankshaft and camshaft stay in place. The brand new timing belt must be put in with piston primary at TDC.
Installing the Honda Pilot Timing Belt
When you find yourself prepared to put in the brand new timing belt, take away the battery clamp-down bolt from the belt rear cowl. Remove the auto-tensioner as effectively and put together the tensioner for belt set up.
Utilizing a vise, fastidiously compress the rod contained in the tensioner till the holes within the rod and tensioner align. Then insert a zero.08-inch pin by each holes to maintain them in place. Then set up again the tensioner in place and ensure you have entry to the pin for removing.

The loafer pulley ought to be capable to transfer however mustn’t come off. Now, set up the timing belt in a counter-clockwise course beginning on the crankshaft sprocket. As soon as put in, tighten the loafer pulley bolt to 33 ft. lbs. (44Nm) utilizing a torque wrench and take away the pin from the auto-tensioner.
With the timing belt in place, you’ll be able to take away the battery clamp-down bolt and set up the lower half of the aspect engine mount bracket, the belt information plate, the lower cowl, the crankshaft pulley and the front and rear higher covers, in that order.
