Subaru Crosstrek Service Manual: Installation

1. CYLINDER HEAD RH

1. Clean the bolt holes in the cylinder block RH.

CAUTION:

To avoid erroneous tightening of the bolts, clean out the bolt holes sufficiently by blowing with compressed air to eliminate engine coolant etc.

2. Apply liquid gasket to both sides of the cylinder head gasket RH as shown in the figure.

NOTE:

• Use a new cylinder head gasket RH.

• Before applying liquid gasket, degrease the mating surface of cylinder blocks RH and cylinder head RH.

• Install within 5 min. after applying liquid gasket.

Liquid gasket:

THREE BOND 1217G (Part No. K0877Y0100), THREE BOND 1217H or equivalent

Liquid gasket applying diameter:

3±1 mm (0.1181±0.0394 in)

3. Attach the cylinder head gasket RH.

NOTE:

Check that liquid gasket RH is squeezed out from the cylinder head gasket.

4. Install the cylinder head RH to the cylinder block RH.

CAUTION:

Be careful not to scratch the mating surface of cylinder head RH and cylinder block RH.

(1) Clean the cylinder head bolt threads and apply sufficient engine oil to the washer and cylinder head bolts threads.

(2) Mount the cylinder head RH onto the cylinder block RH, and tighten all bolts with a torque of 29 N·m (3.0 kgf-m, 21.4 ft-lb) in numerical order as shown in the figure.

(3) Tighten all cylinder head bolts further with a torque of 100 N·m (10.2 kgf-m, 73.8 ft-lb) in numerical order as shown in the figure.

CAUTION:

If the bolt makes stick-slip sound during tightening, repeat the procedure from step 1). In that case, the cylinder head gasket RH can be reused. But it is necessary to remove liquid gasket completely from cylinder block RH, cylinder head RH and cylinder head gasket RH and re-apply to them.

(4) Loosen all cylinder head bolts 180° in numerical order as shown in the figure, and then loosen all cylinder head bolts 180° further in numerical order as shown in the figure.

(5) Tighten all cylinder head bolts with a torque of 42 N·m (4.3 kgf-m, 31.0 ft-lb) in numerical order as shown in the figure.

(6) Using angle gauge, tighten all cylinder head bolts with specified angle in numerical order as shown in the figure.

Tightening angle:

80°±2°

(7) Using angle gauge, tighten the cylinder head bolts (2 places) with specified angle in numerical order as shown in the figure.

Tightening angle:

75°±2°

(8) Using angle gauge, tighten the cylinder head bolts (4 places) with specified angle in numerical order as shown in the figure.

NOTE:

After tightening, if the liquid gasket is squeezed out onto the seal surface of the chain cover, completely remove any squeezed-out liquid gasket.

Tightening angle:

30°±2°
