Honda recommends that the timing belt be modified each a hundred and five,000 miles beneath regular service or 60,000 miles beneath extreme service. The earlier service historical past is the main contributing consider its dedication. Honda has recognized the 2000 Civic DX engine as an interference engine. That is essential as a result of it’s designed with small chamber cylinder heads and valve to piston clearance is just current when the timing belt is in place. If the belt ought to break when the engine is working, in all chance the valves will contact the pistons leading to critical injury. The ethical of this story is all the time change the timing belt at or earlier than it’s time to accomplish that.
Honda Civic DX Install the Timing Belt Instructions
Loosen the lug nuts on the driver’s aspect front wheel utilizing the lug wrench. Increase the front of the automobile with a jack and place jack stands behind the front wheels on the subframe rails on each side of the automobile. Decrease the automobile so it rests on the stands. Proceed remove the lug nuts on the left front wheel and take away the wheel.
Remove the interior splash protect, utilizing a socket. Place the ground jack underneath the oil pan with a block of wooden on the lifting level. It will shield the oil pan. Elevate the jack simply sufficient to the touch the pan. Remove the accent drive belts. The alternator and air compressor belt is tensioned at the alternator. There’s a slotted bracket beneath the alternator with an adjusting bolt and locknut.
Loosen the high pivot bolt with a socket and ratchet. Loosen the lower locknut going through the fender utilizing a socket and ratchet. Utilizing the identical device, rotate the adjusting bolt counterclockwise to alleviate the rigidity. Elevate the belt off the alternator. Loosen the energy steering belt in the identical method, besides the bracket is on the backside of the pump. Loosen the pivot bolt at the prime and the locknut on the backside adjuster bracket. Flip the adjuster nut counterclockwise to alleviate the rigidity. Remove the belt. Remove the energy steering pivot and adjuster bolt and transfer the energy steering pump apart so the timing cowl might be eliminated. Don’t take away the hoses.
Remove the high engine mount, utilizing a socket and ratchet to take away the bolts. Remove the valve cowl bolts with the socket and ratchet. Label every spark plug wire and take away them from the cylinder head and valve cowl. Remove the valve cowl from the engine.Remove the timing belt higher cowl, utilizing a socket and ratchet. Utilizing a socket and ratchet on the crankshaft bolt, flip the crankshaft counterclockwise, the regular path of rotation, till the timing groove on the crankshaft pulley aligns with the two vertical tips about the lower timing belt cowl at 12 o’clock.
Verify the alignment on the high camshaft sprocket. The phrase “Up” have to be straight up at the prime of the sprocket. There’s a groove in the sprocket at the 9 o’clock and three o’clock positions that should align with the cylinder head higher floor. One other timing mark is on the sprocket at the 7 o’clock place that should align with the left finish of a raised piece beneath the sprocket. If the marks don’t align, flip the crankshaft one full flip counterclockwise and they’ll align.
Remove the crankshaft pulley bolt, utilizing the breaker bar and a socket. Pull off the pulley. Remove the lower timing belt cowl, utilizing a socket and ratchet. Loosen the timing belt tensioner bolt and push the tensioner away from the belt. Loosely tighten the tensioner bolt to carry it in place. Remove the belt.
Recheck the timing marks to ensure they’re nonetheless in place earlier than putting in the timing belt. The crankshaft timing mark with the pulley eliminated is a notch on the face of the crankshaft sprocket between the gear enamel. It should align with an arrow on the block at the 1 o’clock place. Install the new belt beginning at the crankshaft pulley. Make completely positive that the pressure aspect of the belt is reverse the tensioner. Maintain the belt tight and stretch it from the crank pulley, round the adjuster pulley, round the water pump and round the camshaft pulley.
Test the timing marks on the camshaft sprocket and ensure the phrase “Up” is at the 12 o’clock place and the notches at the three and 9 o’clock positions are aligned with the mating floor of the cylinder head. The timing mark on the crankshaft sprocket is a notch on the sprocket and it should align with an arrow on the block at 1 o’clock. Loosen the tensioner bolt and permit it to use stress to the belt. Tighten the tensioner bolt to carry it in place for the second.
Install the crankshaft pulley and bolt. Flip the crankshaft counterclockwise six turns and realign all the timing marks. The timing marks on the crankshaft and camshaft should nonetheless be in excellent alignment. Loosen the timing belt tensioner bolt. Torque the tensioner bolt to 33 foot-kilos. If they do not align, take away the belt and repeat the means of seating the belt.
Remove the crankshaft bolt and pulley. Install the lower timing belt cowl. Install the crankshaft pulley and torque the bolt to 14 foot-kilos plus an extra ninety levels. Install the higher timing belt cowl. Install the higher engine mount to dam bolts and torque them to forty foot-kilos. Install the by way of bolt and nut and tighten it to forty seven foot-kilos. Install the valve cowl onto the cylinder head. Install the valve cowl mounting bolts and tighten to 7.2 foot-kilos with the torque wrench. Install every spark plug wire based on the labels made beforehand.
Install the energy steering pump. Install the energy steering belt, the alternator belt and air compressor belt. Pressure the energy steering belt by rotating the lower adjuster bolt clockwise. Place the fish weighing scale in the middle of the largest span between pulleys. Maintain the small ruler base even with the high of the belt. Apply 22 kilos of strain upward on the belt. The strain is appropriate when the belt could be lifted or deflected by three/eight inch. Regulate the tensioner till that is achieved.
Torque the energy steering adjuster bolt to 17 foot-kilos. Torque the pivot bolt to 33 foot-kilos. The identical applies for the alternator and air compressor adjuster nut at 17 foot-kilos and the pivot at 33 foot-kilos. Install the interior splash protect. Install the wheel and torque the lug nuts to eighty foot-kilos. Elevate the automobile with the flooring jack and take away the jack stands. Decrease the automotive.
