Water pump torque TOYOTA CAMRY 2000 Service Repair Manual

The 5S±FE engine is an in±line, 4±cylinder engine with the cylinders numbered 1±2±3±4
from the front. The crankshaft is supported by five bearings inside the crankcase. These bearings
are made of aluminum alloy.
The crankshaft is integrated with eight weights for balance. Oil holes are placed in the center of
the crankshaft to supply oil to the connecting rods, bearing, pistons and other components.
The firing order is 1±3±4±2. The cylinder head is made of aluminum alloy, with a cross flow
type intake and exhaust layout and with pent±roof type combustion chambers. The spark plugs
are located in the center of the combustion chambers.
The intake manifold has four independent long ports and utilizes the inertial supercharging effect
to improve engine torque at low and medium speeds.
Exhaust and intake valves are equipped with irregular pitch springs made of special valve spring
carbon steel which are capable of functioning no matter what the engine speed.
The intake camshaft is driven by a timing belt, and a gear on the intake camshaft engages with
a gear on the exhaust camshaft to drive it. The cam journal is supported at five places between
the valve lifters of each cylinder and on the front end of the cylinder head. Lubrication of the cam
journals and gears is accomplished by oil being supplied through the oiler port in the center of the
camshaft.
Adjustment of the valve clearance is done by means of an outer shim type system, in which valve
adjusting shims are located above the valve lifters. This permits replacement of the shims without
removal of the camshafts.
Pistons are made of high temperature±resistant aluminum alloy, and a depression is built into
the piston head to prevent interference with the valves.
Piston pins are the full±floating type, with the pins fastened to neither the piston boss nor the
connecting rods. Instead, snap rings are fitted on both ends of the pins, preventing the pins from
falling out.
The No.1 compression ring is made of steel and the No.2 compression ring is made of cast iron.
The oil ring is made of a combination of steel and stainless steel. The outer diameter of each
piston ring is slightly larger than the diameter of the piston and the flexibility of the rings allows
them to hug the cylinder walls when they are mounted on the piston. Compression rings No.1 and
No.2 work to prevent gas leakage from the cylinder and the oil ring works to scrape oil off the
cylinder walls to prevent it from entering the combustion chambers.
The cylinder block is made of cast iron. It has four cylinders which are approximately twice the
length of the piston stroke. The top of each cylinder is closed off by the cylinder head and the
lower end of the cylinders becomes the crankcase, in which the crankshaft is installed. In
addition, the cylinder block contains a water jacket, through which coolant is pumped to cool the
cylinders.
The oil pan is bolted onto the bottom of the cylinder block. The oil pan is an oil reservoir made of
pressed sheet steel. A dividing plate is included 'inside the oil pan to keep sufficient oil in the
bottom of the pan even when the vehicle is tilted. This dividing plate also prevents the oil from
making waves when the vehicle is stopped suddenly and the oil shifts away from the oil pump
suction pipe.
The 5S±FE engine uses two balance shafts. The balance shafts are fitted in balance shaft
housings that are located at the bottom of the cylinder block. The No. 1 balance shaft is driven by
the drive gear of the crankshaft No.3 counterweight at twice the speed of the crankshaft. The No.
2 balance shaft is driven by the No±1 balance shaft at the same speed in the same direction as the
crankshaft. The balance shafts are designed to eliminate secondary inertia force from the engine,
thereby reducing the engine noise (booming noise).
