Repair And Fix it

Audi AG is a German company that makes cars in a range of styles. A V6 engine is common in late-model Audi cars, such as the A6. This executive car typically features the AHA series engine, a six-cylinder, 2.8-liter engine with a double overhead camshaft. This engine has a timing belt to synchronize the movements of the crankshaft and camshafts. The timing belt requires regular replacement, unlike a timing chain, which can last the lifetime of the car.

Instructions

1

Disconnect the negative battery cable with a socket wrench. Detach the accessory drive belt from its pulleys. Turn the crankshaft clockwise by hand to align the timing mark on the crankshaft pulley with the timing mark on the crankcase. The timing marks on the camshaft must also align with their respective timing marks on the crankcase.

2

Remove the plug from the left side of the engine block by the crankshaft with a socket wrench. Align the timing marks on the crankshaft again if necessary. Connect Tool No. 3242 to the crankshaft and tighten it slightly to hold it in place.

3

Disconnect the upper timing belt covers, crankshaft vibration damper and lower timing belt cover in that order. Loosen the mounting bolts for the camshaft sprockets with a socket wrench, and release the sprockets from the ends of the camshafts.

4

Turn the roller for the timing belt tensioner clockwise with an 8 mm Allen wrench to compress the tensioner. Place a 2 mm spring pin through the holes in the tensioner housing and plunger to hold the plunger in place. Turn the tensioner counterclockwise to release the tensioner.

5

Remove the mounting bolts for the crankshaft damper with a socket wrench and detach the damper from the crankshaft. Disconnect the serpentine belt from the idler pulley and remove the guard for the crankshaft damper. Detach the timing belt from its pulleys.

6

Align the timing marks for the camshaft and crankshaft pulleys, if necessary. Place the new timing belt onto the pulleys, so that the arrow on the timing belt points in the clockwise direction.

7

Turn the roller for the timing belt tensioner clockwise with an 8 mm Allen wrench to compress the tensioner. Pull the 2 mm spring pin from the housing of the tensioner plunger. Turn the tensioner roller counterclockwise to apply tension to the timing belt.

8

Connect the damper guard for the crankshaft and attach the serpentine belt to the idler pulley. Tighten the mounting bolts for the idler pulley bolts to 33 foot-pounds with a torque wrench. Replace the crankshaft damper and tighten its mounting bolts to 15 foot-pounds. Fasten the mounting bolts for the camshaft sprockets with a socket wrench. Install the timing belt covers.

9

Remove Tool No. 3242 from the crankshaft pulley. Install the sealing plug into its hole on the lower left side of the engine with a socket wrench. Attach the accessory drive belt and connect the cable for the negative battery terminal.

The oil pan in your 2003 V6 Ford Mustang is secured to the bottom of the engine block, and it holds a certain amount of oil for the lubrication system to do its job. If the pan in your Mustang becomes damaged and begins to leak oil, you need to install a new pan. You can replace the pan at home with the help of some special tools.

Instructions

Removing the Used Pan

1

Park your Mustang on level ground. Raise the front of the vehicle with a floor jack. Position two jack stands under the frame for support. Apply the parking brake, and block the rear wheels with chocks.

2

Place a clean, large drain pan under the engine oil pan. Remove the drain plug with a wrench. Allow the oil to drain completely. Cover the pan to keep dirt off the oil for later reuse.

3

Remove the black negative battery cable, air cleaner tube and coolant recovery reservoir with a wrench.

4

Detach the upper radiator shield with a ratchet and socket.

5

Slide the drain pan under the oil filter. Remove the oil filter with a filter wrench.

6

Set up engine lifting brackets and a support fixture on top of the engine compartment, and secure the engine.

7

Remove the left and right motor mounts with a ratchet and socket.

8

Take off the starter motor with a ratchet, short ratchet extension and socket.

9

Unfasten and lower the engine support bracket just enough to gain access to all the oil pan mounting bolts.

10

Detach the wiring harness bracket next to the oil pan. Remove the pan with a ratchet, ratchet extension and socket. Remove the oil pan from the vehicle.

Installing the New Oil Pan

11

Clean the engine block mating surface with a gasket scraper and solvent. Let it dry completely. Apply a light coat of silicone sealant to the oil pan gasket mating surface. Set a new pan gasket on the pan. Position the pan under the engine block. Install the pan mounting bolts, and tighten them with your fingers. Tighten the bolts alternately with a torque wrench, working toward the rear of the engine, to 44 inch-pounds (5 Nm) and then to 88 inch-pounds (10 Nm). Tighten the three bolts that hold the transmission housing bell to 33 foot-pounds (45 Nm). Make sure the pan drain plug is correctly installed.

12

Reinstall the wiring harness to the oil pan and the engine support bracket. Tighten the larger upper bolts to 85 foot-pounds (115 Nm) and the smaller ones to 68 foot-pounds (90 Nm) with the torque wrench.

13

Replace the starter motor, and tighten the bolts to 18 foot-pounds (15 Nm) with the torque wrench.

14

Install the left and right motor mounts, and tighten the bolts to 85 foot-pounds (115 Nm) with the torque wrench.

15

Replace the oil filter by hand. Replace the upper radiator shield with the ratchet and socket.

16

Lower your Mustang with the floor jack.

17

Connect the black negative battery cable, air cleaner tube and coolant recovery reservoir with the wrench.

18

Refill the engine with oil using a small funnel.

19

Check the oil pan for leaks.
