Toyota RAV4 (XA40) 2013-2018 Service Manual: Valve clearance
Adjustment
- Disconnect cable from negative battery
terminal
Caution:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and seat belt pretensioner activation.
- Remove front wheel rh
- Remove no. 1 Engine under cover
- Remove front fender apron rh
- Remove no. 1 Engine cover (see page em-22)
- Remove ignition coil assembly (see page ig-9)
- Remove spark plug
- Remove the 4 spark plugs.
- Remove cylinder head cover sub-assembly
(see page em-24)
- Set no. 1 Cylinder to tdc/compression (see
page em-25)
- Check valve clearance
- Check only the valves indicated.
- Using a feeler gauge, measure the clearance
between the valve lifter and camshaft.
Standard valve clearance (cold)
- Record any out-of-specification valve clearance
measurements. They will be used later to
determine the required replacement valve
clearance lifters.
- Turn the crankshaft 1 revolution (360°) and set the
no. 4 Cylinder to the tdc/compression.
- Check only the valves indicated.
- Using a feeler gauge, measure the clearance
between the valve lifter and camshaft.
Standard valve clearance (cold)
- Record any out-of-specification valve clearance
measurements. They will be used later to
determine the required replacement valve
lifters.
- Adjust valve clearance
- Remove the no. 2 Camshaft (see page em-60).
- Remove the camshaft (see page em-61).
- Remove the valve lifters.
- Using a micrometer, measure the thickness of the
removed valve lifters.
- Calculate the thickness of a new lifter so that the
valve clearance comes within the specified values.
New lifter thickness
Calculation example (intake):
- Measured intake valve clearance = 0.40 Mm
(0.0158 In.)
(Measured - specification = excess clearance)
(a)0.40 Mm (0.0158 In.) - 0.24 Mm (0.0095 In.) =
0.16 Mm (0.0063 In.)
- Measured used lifter thickness = 5.250 Mm
(0.2067 In.)
- New lifter thickness = 5.410 Mm (0.2130 In.)
(Excess clearance + used lifter thickness = ideal
new lifter)
(a)0.16 Mm (0.0063 In.) + 5.250 Mm (0.2067 In.)
= 5.410 Mm (0.2130 In.)
- Closest new lifter = 5.420 Mm (0.2134 In.)
– Select no. 42 Lifter
- Select a new lifter with a thickness as close as
possible to the calculated values.
Hint:
- Lifters are available in 35 sizes in increments of
0.020 Mm (0.0008 In.), From 5.060 To 5.740 Mm
(0.1992 To 0.2260 In.
- The identification number inside the valve lifters
shows the value to 2 decimal places. (The
illustration shows 5.420 Mm (0.2134 In.)
- Valve lifter selection chart (intake).
Standard intake valve clearance (cold):
0.19 To 0.29 Mm (0.0075 To 0.0114 In.)
Example:
The 5.250 Mm (0.2067 In.) Lifter is installed, and the
measured clearance is 0.400 Mm (0.0157 In.).
Replace the 5.250 Mm (0.2067 In.) Lifter with a new
no. 42 Lifter.
- Valve lifter selection chart (exhaust).
Standard exhaust valve clearance (cold):
0.38 To 0.48 Mm (0.0150 To 0.0189 In.)
Example:
The 5.340 Mm (0.2102 In.) Lifter is installed, and the
measured clearance is 0.430 Mm (0.0169 In.).
Replace the 5.340 Mm (0.2102 In.) Lifter with a new
no. 42 Lifter.
- Install the selected valve lifter.
- Install camshaft
- Apply a light coat of engine oil to the journal portion
of the camshaft.
- Install the timing chain onto the camshaft timing
gear with the paint mark aligned with the timing
mark in the camshaft timing gear as shown in the
illustration.
- Examine the front marks and numbers, and check
that the order is as shown in the illustration. Then
install the bearing caps into the cylinder head.
- Apply a light coat of engine oil on the threads and
under the heads of the bearing cap bolts.
- Using several steps, uniformly tighten the 10
bearing cap bolts in the sequence shown in the
illustration.
Torque: 29.5 N*m (301 kgf*cm, 22 ft.*Lbf) for no.
1 Bearing cap
9.0 N*m (92 kgf*cm, 80 in.*Lbf) for no. 3
Bearing cap
- Install no. 2 Camshaft
- Apply a light coat of engine oil to the journal portion
of the no. 2 Camshaft.
- Put the no. 2 Camshaft on the cylinder head with the
paint mark of the chain aligned with the timing mark
on the camshaft timing sprocket.
- While holding the no. 2 Camshaft by hand,
temporarily tighten the camshaft timing sprocket set
bolt.
- Examine the front marks and numbers, and check
that the order is as shown in the illustration. Then
install the bearing caps onto the cylinder head.
- Apply a light coat of engine oil to the threads and
under the heads of the bearing cap bolts.
- Using several steps, uniformly tighten the 10
bearing cap bolts in the sequence shown in the
illustration.
Torque: 29.5 N*m (301 kgf*cm, 22 ft.*Lbf) for no.
2 Bearing cap
9.0 N*m (92 kgf*cm, 80 in.*Lbf) for no. 3
Bearing cap
- While holding the camshaft with a wrench, tighten
the camshaft timing sprocket set bolt.
Torque: 54 n*m (551 kgf*cm, 40 ft.*Lbf)
Notice:
Be careful not to damage the valve lifter.
- Check that the paint marks on the chain are aligned
with the timing marks on the camshaft timing gear
and camshaft timing sprocket. Also, check that the
crankshaft pulley groove is aligned with the timing
mark "0" of the timing chain cover.
- Install no. 1 Chain tensioner
- Release the ratchet pawl, then fully push in the
plunger and hook the hook to the pin so that the
plunger is in the position shown in the illustration.
- Install a new gasket and the chain tensioner with the
2 nuts
Torque: 9.0 N*m (92 kgf*cm, 80 in.*Lbf)
Notice:
When installing the chain tensioner, set the
hook again if the hook releases the plunger.
- Turn the crankshaft counterclockwise, then
disconnect the plunger knock pin from the hook.
- Turn the crankshaft clockwise, then check that the
plunger is extended.
- Install cylinder head cover sub-assembly
(see page em-40)
- Install spark plug
- Install the 4 spark plugs.
Torque: 25 n*m (255 kgf*cm, 18 ft.*Lbf)
