Step 1: Disconnect – (neg) battery cable.

Step 2: Remove engine covers 4 bolts with 10mm socket and wrench.

Step 3: Set the park brake, jack up the front end and rest it securely on jack stands.

Step 4: Remove passenger side front wheel (13/16 socket, 4 lug nuts)

Step 5: Remove the 2 spark plug cables shown by pulling from the rubber boot.

Step 6: Remove both coil packs (2 bolts each, 10mm socket).

Step 7: Using a 3/8 ratchet, extension, and 13/16 socket unscrew all 4 spark plugs. Fish out the spark plugs with a telescoping magnet as shown. (it is good practice to discard old plugs and install new ones once we are ready to go back together)

Step 8: Remove the upper timing belt cover. There are 5 bolts (10mm) and one engine cover mount. Only once these are removed can you pull the plastic cover off.

Step 9: Install a compression gauge into the #1 spark plug port. This is the closest to the passenger side front tire.

Step 10: Remove the plastic wheel well cover shown (3 bolts 10mm)

Step 11: Using a 7/8 deep socket and ratchet turn the now exposed crank shaft pulley clockwise until your compression gauge reads pressure. Now we know we are on the compression stroke on the # 1 cylinder. Turn the crank pulley until the marks on both cam sprockets line up with the marks shown. I have painted them red so you can identify them easier.

Step 12: Lock the cams in place with a tool such as the one shown.

Step 13: with a 12 and 14 mm wrench loosen the 2 bolts on the alternator and unthread the tensioner until it can be rotated out of the way.

Step 14: Using a 13mm socket and ratchet loosen the tensioner pulley shown. Now both serpentine belts can be removed ( again it is a good time to replace old belts).

Step 15: Using a 3/8 “ impact and a 12 mm deep socket remove the crank shaft pulley.

Step 16: With a 10mm ratchet wrench remove the water pump pulley. You may have to place a small pry bar in between the heads of the bolts to stop it from spinning.

Step 17: Support the engine enough to relief pressure at the passenger side engine mount. You can do so either by placing a piece of wood, at least 1.5 inches thick and equal in geometry to your oil pan on a floor jack and lifting only enough to take tension off of the previously discussed engine mount. Preferably you will use a hoist from above with a chain hooked to the 2 engine support brackets shown.

Step 18: Remove the 3 engine mount bolts and 1 nut with 17mm deep socket and a wrench. Now remove the engine mount to gain access to the lower timing belt cover. Note if you find damage to the upper or lower timing belt cover they should be replaced.

Step 19: Remove all 8 bolts from lower timing belt cover with 10mm socket and wrench. Careful not to break it pull the lower cover down through the bottom.

Step 20: Now it is time to make sure all 5 of our timing marks are “ in time”. The 5 marks are the 2 previously discussed cams, the crank, the oil pump, and finally the rocker shaft. We already have our cams set now we check the other 3.

Step 21: Now that our engine is in time we remove the timing belt tensioners starting with the outer belt. Loosen both bolts on the tensioner about 1 turn, then completely remove the bottom bolt this will release tension on the outer belt now remove the top bolt completely, careful not to move any gears out of time. Once the tensioner is removed remove the outer timing belt. If the old tensioner is to be reused compress it in a vice slowly (over a period of 5 minutes) until the hole lines up so you can install a retaining pin as shown.

Step 22: Remove the crank position sensors 2 bolts with a 10 mm wrench, delicately hang the sensor out of the way.

Step 23: With a 12 mm socket wrench remove the tensioner pulley. To remove the inner timing belt (the smaller of the 2) you will have to rotate the crank allowing the belt to roll out from behind the cranks sensor plate.

Step 24: With a 12 mm socket wrench remove the tensioner pulley assembly. Replace the old pulley by unbolting it form the assembly torque the new pulley to the assembly to 40 ft lbs. With new lock washer.

Step 25: Drain the coolant out of the radiator into a clean bucket if you are re using it. with a ¼ inch air ratchet and a 12 mm socket remove the ring of 5 bolts around the water pump. With a razor blade scrape the remaining gasket and silicone from the engine block as shown, then clean and dry the surface.

Step 26: Figure out which side of the water pump gasket faces the engine block place a thin bead of silicone rtv on that side of the gasket and stick it to the side of the engine, making certain that the bolt holes on both the gasket and the engine block are aligned. You will notice a metal tube that protrudes into the water pump sealing with a rubber o-ring. Replace with a new freshly greased o-ring, make sure you align this hose with its mating orifice on the back side of the water pump. Now finagle the new water pump in place from the top and secure with the top bolt. Do not tighten this bolt yet. Install the rest of the bolts in the hole in whence they came only finger tight. Remember to install the alternator mount on the water pump as shown. Now in a star pattern torque each bolt to 19 ft lbs.

Step 27: If your timing belt kit came with a new idler pulley (which it should have) you must now remove the power steering pump it has 4 bolts 2 facing the front side of the engine and 2 facing the right side of the engine. Once these bolts are removed the power steering pump can be slid out of the way of the idler pulley.

Step 28: Remove the idler pulleys 1 bolt in the center with a 14mm socket wrench. Install new pulley and torque to 40 ft, lbs. Now reinstall the power steering pump and oil dip stick tube retrained by the bottom front bolt. Torque these to 40 ft lbs as well.

Step 29: Lace the inner timing belt on the crank shaft and balance shaft pulleys keeping their timing marks in place now install the tensioner with 12mm socket to 15 ft lbs.

Step 30: Reinstall the crank position sensor torque to 12 ft. lbs.

Step 31: Now we are ready to install our new outer timing belt tensioner with a new bearing and pinned gas shock, lace the belt starting with the tensioner pulley, crankshaft sprocket, oil pump sprocket, guide pulley, right hand cam sprocket, and finally the left hand cam sprocket. Make sure all your timing marks are still aligned if not do not pull the pin on the tensioner uninstall belt and try again. Once you have your belts on and marks aligned pull the tensioner pin. With a ratchet turn the engine over clockwise 2 revolutions to insure no interference is taking place between the valves and pistons. Insure the marks have all lined back up and reassemble.

Step 32: Insert the lower timing belt cover in place through the same passage it was removed, and loosely install the bolts. Once they are all in place snug them up equally until they are hand tight.

Step 33: Install the water pump pulley torquing the 4 bolts to about 18 lbs.

Step 34: Now install the upper timing belt cover be sure to attach the engine cover mount to the upper left cover bolt shown.

Step 35: Install crankshaft pulley and torque the 4 bolts to 55 ft. lbs.

Step 36: Lace the inner cerpintine belt (the smaller one) around the back side of the crankshaft pulley, around the water pump pulley, and around the alternator pulley. Use the adjusting screw on the altrnator bracket to apply tension to the belt until the slack is taken out of it. Now tighten the remaining 2 alternator bolts.

Step 37: Now lace the outer cerpintine belt around the a/c comprssor, the power steering pump the tensioner pulley, and the crankshaft pulley.

Step 40: Install the motor mount and torquer hardware to 85 ft lbs. Remove hoist or jack as the engine is now supported in the vehicle.

Step 41: Fasten the power steering fluid line to its retainer snuggly as shown.

Step 42: Install the new spark plugs and torque them to 19 ft. lbs.

Step 43: Install the spark plug cables and coil packs. Tighten the bolts for the coil packs hand tight.

Step 44: Now replace the plastic engine cover and tighten all 4 bolts hand tight.

Step 45: Install the wheel back on to the vehicle and tighten bolts to 85 ft. lbs.

Step 46: Lower the vehicle back to the ground.

Step 47: Refill the radiator with the proper mix of coolant and water (50/50)

Step 48: Reconnect – (neg) battery cable.

Step 49: check engine oil. Add if needed. And start the engine. Let it warm up checking coolant level periodically.
