How to Remove a 3S FE Cylinder Head

The Toyota 3S-FE engine is a four-cylinder, 2.0-liter engine with a double overhead camshaft. It was produced from 1986 to 2000. During that period, it was the engine that powered various Toyota vehicles, including Camry models for 1987 through 1992. The cylinder block in the 3S-FE engine is iron, and the cylinder head is an aluminum alloy. The removal of the cylinder head for this engine should require four to five hours for an experienced mechanic.

Instructions

1

Put a drain pan under the radiator, and open the radiator drain. Allow the coolant in the radiator to drain into the pan. Replace the drain plug. Seal the container, and store it for later use.

2

Disconnect the throttle cable and its bracket from the throttle body with a socket wrench if your vehicle has an automatic transmission. For all vehicles, detach the accelerator cable and its bracket from the throttle body. Remove the actuator and its bracket from the cruise control if your vehicle is so equipped.

3

Detach the hose from the air cleaner with a socket wrench. Disconnect the alternator and oil pressure gauge from the engine. Loosen the lug nuts on the right front wheel with a lug wrench and raise the vehicle with a floor jack. Support the vehicle with jack stands and disconnect the right front wheel assembly. Detach the splash shield from the right front wheel well.

4

Disconnect the lower cross member for the suspension with a socket wrench. Remove the exhaust pipe from the catalytic converter and disconnect the distributor from the engine. Disconnect the electrical connector for the water temperature sender gauge and remove the sender gauge from the vehicle. Detach the switch connector for the cold start injector.

5

Disconnect the radiator hoses and emission control hoses from the engine with a socket wrench. Detach the water bypass pipe and the exhaust gas recirculation valve from the engine. Disconnect the air hose for the throttle body and remove the throttle body. Remove the hoses from the power steering unit if your vehicle is so equipped.

6

Disconnect the intake manifold from the engine with a socket wrench and discard the gasket. Disconnect the fuel pipe from the injectors and remove the injectors from the engine. Unscrew the spark plugs and remove them from the engine.

7

Disconnect the camshaft pulley and the No. 1 idler pulley with a socket wrench. Remove the spring from the timing belt tensioner and detach the No. 3 cover for the timing belt. Support the timing belt to prevent it from shifting on the crankshaft pulley.

8

Disconnect the grommets on the cylinder head cover with a socket wrench. Label the grommets to ensure you install them in their original positions. Remove both camshafts from the engine.

9

Remove the 10 mounting bolts on the cylinder head with a socket wrench by loosening them in three separate passes. Tap the cylinder head with a rubber mallet to loosen it from the engine block. Place the cylinder head on a clean work surface. Discard the old gasket for the cylinder head. Remove any traces of the gasket from the cylinder head and engine block with a gasket scraper.
