Removal the cylinder head [Toyota Carina T170]

The cylinder head can be removed without removing the engine, and this is the job described below.

Engines 4A-F/FE

• Loosen the water pump pulley nuts, loosen the V-belt adjusting bolt and remove the V-belt (Fig. 5). Loosen the water pump pulley.
• Remove the four spark plugs. You will need a long spark plug wrench for this.
• Disconnect the crankcase ventilation hose from the ventilation valve.
• Unscrew the three cylinder head cover nuts and remove the cover with the sealing washers, nuts and gasket.
• Turn the crankshaft pulley until the mark matches the "0" mark on the timing belt cover. Check if there is any play in the valve tappets of the first cylinder. If there is no play, turn the engine one more revolution. Fig. 7 shows how the crankshaft pulley should be installed so that the engine is at TDC.
• Unscrew the coolant drain pipe (2 bolts).
• Unscrew 2 bolts and remove the exhaust manifold support.
• Loosen 4 bolts and remove the upper heat shield of the exhaust manifold.
• Loosen 3 bolts and 2 nuts of the exhaust manifold and remove the exhaust manifold with gaskets. Loosen 3 bolts and remove the lower heat shield of the exhaust manifold.
• Remove the ignition distributor together with the ignition wires.
• Remove the cooling system inlet housing. To do this, disconnect 2 water hoses, unscrew 2 nuts and a bolt (Fig. 37) and remove the housing.

• On carburetor engines (4A-F), remove the fuel pump (Fig. 38).

• Disconnect the crankcase ventilation hose, disconnect the water hose from the intake manifold and remove the 2 intake manifold support bolts.
• Unscrew 6 bolts and 2 nuts, remove the cable clamp and remove the intake manifold with the gasket.
• Unscrew the upper and lower timing belt covers and remove the gaskets. In total, you need to unscrew 3 bolts on each side.
• When installing the old timing belt, mark it with an arrow indicating the direction of travel and marks the location relative to the camshaft gear and crankshaft pulley, as shown in Fig. 10, but in this case, mark it only on the camshaft gear.
• Loosen the front toothed belt tensioner bolt, push the tensioner all the way to the left, as shown in Fig. 11, and tighten it in this position. Now the toothed belt is free and can be removed. When doing this, remove the belt with tension so that it cannot jump off the crankshaft toothed wheel. Do not allow foreign objects to get into the timing mechanism and do not dirty the belt.
• Loosen the camshaft gear bolt. The shaft should be held as shown in Fig. 12 so that it does not turn.
• Measure the axial clearance of both camshafts. To do this, install a dial indicator on the end of the camshaft, as shown in Fig. 14, and use two screwdrivers to move the camshaft in both directions. Take readings from the dial indicator. The clearance of the inlet camshaft should be between 0.030 and 0.085 mm; the clearance of the exhaust camshaft should be between 0.035 and 0.090 mm.
• Remove both camshafts in accordance with the instructions in Chapter 2.2.
• Using a Torx key, loosen the cylinder head mounting bolts in the sequence shown in Fig. 19. Loosening the bolts in a different sequence may cause the cylinder head to become skewed. Raise the cylinder head. If the head is firmly seated, insert a screwdriver into the place shown in Fig. 20 between the protrusion of the engine block and the head, without damaging the surface. The head sits on pins.

Engine 3S-FE

• Disconnect the battery and drain the coolant.
• Release the generator mounting bar, tilt the generator and remove the drive belt. Remove the generator.
• Loosen the engine lifting brackets and remove the upper generator mount.
• If there is a catalytic converter, remove the exhaust manifold and the catalytic converter or exhaust manifold. Remove all heat shields to gain access to the bolts and nuts.
• After removing the spark plug caps, unscrew the spark plugs using a long spark plug wrench.
• Unscrew the 4 cylinder head cover nuts and remove the cover with sealing washers and cover gasket.
• Remove the fuel injection unit throttle body, disconnect the air hose and air pipe.
• Unscrew the intake manifold support, disconnect the vacuum hose and unscrew the manifold. Remove the manifold with the gasket.
• Turn the crankshaft until the mark on the crankshaft pulley aligns with the "0" mark on the scale on the front side of the engine (see fig. 7). Check that the valves of the first cylinder have clearances. If they switch, turn the crankshaft one more revolution. To avoid mistakes, watch the toothed wheel of the camshaft. There is a hole on the wheel that should coincide with the mark on the camshaft bearing cap, as shown in Fig. 26.
• Remove the cooling system drain assembly housing (2 bolts).
• Remove the ignition distributor with ignition wires.
• Unscrew the cooling system drain pipe. First disconnect the water hoses. Then unscrew 2 bolts and 2 nuts, remove the pipe and gasket, as well as the sealing ring.

• If equipped, remove the EGR valve and control valve. They are located in the location shown in Fig. 31. To remove, disconnect the vacuum hoses, loosen the union nut and loosen the two bolts. Remove the control valve with the gasket. The EGR valve is secured with one bolt.
• Remove the injection pipes and injectors.
• Unscrew 5 bolts and remove the upper timing belt cover. Remove the gasket.
• When installing the old belt, apply an arrow indicating the direction of belt movement and a mark on the belt relative to the camshaft wheel, as shown in Fig. 27.
• Loosen the toothed belt tensioner bolt, push the tensioner all the way to the left, as shown in Fig. 11, and tighten it in this position. The toothed belt is now free and can be removed. At the same time, ensure that the belt is taut so that it cannot jump off the crankshaft toothed wheel.
• Loosen the camshaft wheel bolt. Since the shaft rotates, it should be held. Usually, the device shown in Fig. 30 is used for this, which is inserted into two holes in the wheel, but you can also insert a long rod into one of the holes, turn the wheel until the rod rests against the cylinder head and then loosen the bolt. Remove the washer and gear wheel.
• Unscrew 4 bolts and unscrew the cover from the front side of the cylinder head. The cover is shown in Fig. 40.

• Before removing the camshafts, their axial clearance should be measured. These works have already been described above. After this, remove the camshafts.
• Using a Torx key, loosen the cylinder head mounting bolts in the sequence shown in Fig. 19. Loosening the bolts in a different sequence may cause the cylinder head to become skewed. Raise the cylinder head. If the head is stuck, insert a screwdriver, as shown in Fig. 20, between the ledge on the engine block and the head, without damaging the surface. The head sits on pins.
