The R family of engines from Toyota, produced from 1981-85, were four-cylinder gasoline engines for front-wheel-drive vehicles. The 22R had a displacement of 2.4 liters and a single overhead camshaft. It used a timing chain, which had a lower risk of causing engine damage than a timing belt. The procedure for removing the timing chain from a 22R engine is generally the same for all vehicles.

Instructions

1

Disconnect the cable from the batterys negative terminal. This prevents the engine from starting during the timing chain removal. Remove the mounting bolts for the cylinder head with a socket wrench. Pry the cylinder head from the mounting dowels with pry bars in front and behind the valve rocker assembly. Lift the cylinder head off the mounting dowels.

2

Drain the radiator, and detach the hoses from the radiator. Disconnect the mounting bolts for the radiator, and remove the radiator from the vehicle with a socket wrench. Perform this step only if the radiator blocks your access to the timing chain.

3

Disconnect the oil pan with a socket wrench if it blocks your access to the timing chain.

4

Relieve the tension on the drive belts with the belt tensioner, and remove the drive belts from their pulleys. Attach a suitable puller to the crankshaft pulley, and remove the pulley from the crankshaft.

5

Remove the retaining bolts for the water bypass tube with a socket wrench, and detach the tube. Disconnect the heater tube. Remove the bolt for the alternator bracket, and push the bracket towards the alternator to access the timing chain cover.

6

Disconnect the mounting bolts on the timing chain cover with a socket wrench, and remove the cover from the engine. Lift the timing chain off the camshaft damper. Slide the timing chain and camshaft sprocket off the camshaft.

7

Pull the crankshaft sprocket from the crankshaft by hand. Lift the oil pump spline from the crankshaft, and pull it from the crankshaft by hand.

The Pontiac Grand Am SE came standard with a 150-horsepower, 2.4-liter four-cylinder engine, but did have an optional 170-horsepower, 3.4-liter V-6 engine, which some people know as the 3400 V-6. The 2000 Grand Am SE used a muffler-like component, the catalytic converter, to convert the toxic gasses in the exhaust to less harmful ones. Replacing the cat on the 2000 Grand Am SE 3400 is a straightforward task, thanks to the vehicles simple exhaust design.

Instructions

Removal

1

Allow the vehicle to sit until the engine is cool to the touch, then allow it to sit for an additional hour to allow the exhaust and catalytic converter to cool completely.

2

Lift the front of the Grand Am with a floor jack and slide jack stands under its subframe. Lower the vehicle onto the jack stands.

3

Crawl under the center of the vehicle and find the catalytic converter-and-front pipe assembly. Position a pair of jack stands under the catalytic converter-and-front pipe assembly to support it.

4

Remove the three bolts securing the catalytic converter-and-front pipe assembly to the intermediate pipe -- the pipe to the rear of the catalytic converter -- using a ratchet and socket.

5

Unfasten the two bolts securing the catalytic converter-and-front pipe assembly to the exhaust manifold crossover pipe, which is the pipe connecting the front and rear exhaust manifolds, using a ratchet and socket. Slowly lower the catalytic converter-and-front pipe assembly and remove it from the vehicle.

6

Pull the old gaskets from the crossover and intermediate pipes, if needed, and scour the mating surfaces of both pipes with a wire brush.

Installation

7

Crawl under the vehicle with the catalytic converter-and-front pipe assembly in hand and set the assembly on the jack stands to hold it in place.

8

Line up the bolt holes in the catalytic converter-and-front pipe assemblys front-most flange with those in the crossover pipes flange. Slide a new gasket between the flanges, aligning the gaskets bolt holes with those in the flanges, and hand-tighten the two retaining bolts.

9

Align the bolt holes on the catalytic converter-and-front pipe assemblys rearmost flange with those on the intermediate pipes flange. Slide a new gasket between the flanges, aligning the bolt holes in the gasket with those in the flanges, and hand-tighten the bolts.

10

Tighten all five of the catalytic converter-and-front pipe assemblys retaining bolts to 25 foot-pounds using a torque wrench and socket.

11

Raise the Grand Am off the jack stands and remove the stands. Lower the vehicle to the ground.

International Harvester manufactured the 7.3-liter diesel engines that appear in Ford trucks from 1988 to 1992. This engine is most common in Ford trucks with a rated carrying capacity of at least 1/2 ton. The 7.3-liter Ford diesel engine uses a single cylinder head for all eight cylinders in the engine. The cylinder head is on top of the engine block and is part of the combustion chamber. The procedure for removing the cylinder head from a 7.3-liter engine is the same for all Ford trucks.

Instructions

1

Disconnect the cables from the negative terminals of both batteries with a socket wrench. This prevents anyone from starting the engine while removing the cylinder head.

2

Put a drain pan under the radiator. Remove the drain plug with a socket wrench and allow the coolant in the radiator to drain into the pan. Store the coolant for later use.

3

Detach the shrouds for the radiator fan with a socket wrench. Disconnect the fan and clutch for the radiator as an assembly by using tools T83T-6312-A and T83T-6312-B. The mounting nut for the radiator fan and clutch has a left-hand thread, so you must turn it clockwise to remove the nut.

4

Label the electrical wiring on the alternator so you can connect it correctly later and detach the wiring from the alternator. Disconnect the bolts for the alternator and vacuum pump with a socket wrench. Remove these components from the engine block.

5

Disconnect the coolant hose from the cylinder head with a socket wrench. Remove the fuel injection pump from the engine block. Disconnect the intake manifold and valley cover from the engine block.

6

Raise the vehicle with a floor jack and support it with jack stands. Remove the exhaust pipes from the exhaust manifolds with a socket wrench. Disconnect the clamp and mounting bolt for the oil dipstick tube. Detach the oil dipstick tube from the cylinder head and lower the vehicle.

7

Disconnect the valve covers with a socket wrench and remove the rocker arms from the engine block. Record the position of each push rod, so you can re-install them correctly later. Remove the push rods from the engine block.

8

Remove the fuel injector nozzles and glow plugs from the engine block with a socket wrench. Disconnect the mounting bolts for the cylinder head with a socket wrench. Install lifting eyes on each end of the cylinder block with tool T70P-6000.

9

Lift the cylinder head from the engine block with the lifting eyes. Use caution to prevent the pre-chambers of the cylinder head from falling onto the engine when you remove the cylinder head.
