Title: A25A-FKS (INTAKE / EXHAUST): EXHAUST MANIFOLD: INSTALLATION; 2021 - 2024 MY RAV4 [08/2020 - ] |
INSTALLATION
PROCEDURE
1. INSTALL NO. 2 EXHAUST MANIFOLD HEAT INSULATOR
(a) for Type A:
Install the No. 2 exhaust manifold heat insulator to the exhaust manifold with the 3 bolts.
Torque:
11 N·m {112 kgf·cm, 8 ft·lbf}
(b) for Type B:
Install the No. 2 exhaust manifold heat insulator to the exhaust manifold with the 6 bolts.
Torque:
11 N·m {112 kgf·cm, 8 ft·lbf}
2. INSTALL EXHAUST MANIFOLD
(a) Install a new exhaust manifold to head gasket to the cylinder head sub-assembly.
(b) Temporarily install the exhaust manifold, No. 1 upper front floor heat insulator and No. 1 exhaust manifold heat insulator.
HINT:
At this time, do not install the parts with bolts or nuts.
(c) Using a 12 mm deep socket wrench, temporarily install the exhaust manifold to the cylinder head sub-assembly with 7 new nuts.
|
|
(d) Using the 12 mm deep socket wrench, tighten the 7 nuts in the order shown in the illustration.
Torque:
26 N·m {265 kgf·cm, 19 ft·lbf}
3. INSTALL MANIFOLD STAY
(a) Temporarily install the manifold stay to the exhaust manifold and cylinder block sub-assembly with the bolt and nut.
|
|
(b) Tighten the bolt and nut in the order shown in the illustration.
Torque:
43 N·m {438 kgf·cm, 32 ft·lbf}
4. INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR
(a) for Type A:
Using a 10 mm union nut wrench, install the No. 1 exhaust manifold heat insulator to the exhaust manifold with the 3 bolts.
Torque:
Specified tightening torque :
10 N·m {102 kgf·cm, 7 ft·lbf}
HINT:
-
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
