INTAKE MANIFOLD COLLECTOR Removal and Installation PFP:14003 ABS0095V 1. Electric throttle control actuator 2. Gasket 3. Vacuum hose 4. EVAP canister purge volume control solenoid valve 5. Bracket 6. Intake manifold collector (upper) 7. Intake manifold collector cover 8. Gasket 9. Water hose 10. Bracket 11. Water hose 12. PCV hose 13. Intake manifold collector (lower) REMOVAL WARNING: PBIC2081E To avoid the danger of being scalded, do not drain the engine coolant when the engine is hot. Gasket for intake manifold collector (upper) is secured together with mounting bolt for intake manifold collector (lower). Thus, even when only gasket for upper side is replaced, gasket for lower side must be also replaced. EM-18
1. Remove engine cover with power tool. A EM C D E F KBIA0956E 2. Drain engine coolant, or when water hose is disconnected, attach plug to prevent engine coolant leakage. Refer to CO-10, "Changing Engine Coolant". CAUTION: Perform this step when engine is cold. Do not spill engine coolant on drive belts. 3. Remove air cleaner case and air duct. Refer to EM-16, "AIR CLEANER AND AIR DUCT". 4. Remove electric throttle control actuator as follows: a. Disconnect harness connector. b. Loosen bolts in reverse order as shown in the figure. CAUTION: Handle carefully to avoid any shock to electric throttle control actuator. Do not disassemble. G H I J K L M KBIA0957E 5. Remove fuel sub-tube mounting bolt to disconnect from rear of intake manifold collector (lower). Refer to EM-38, "FUEL INJECTOR AND FUEL TUBE". 6. Disconnect vacuum hose and water hose from intake manifold collector (upper). 7. Remove EVAP canister purge volume control solenoid valve bracket mounting bolt from intake manifold collector (upper). EM-19
8. Loosen bolts in reverse order as shown in the figure to remove intake manifold collector (upper) with power tool. PBIC0773E 9. Remove PCV hose [between intake manifold collector (lower) and rocker cover (right bank)]. 10. Loosen bolts in reverse order as shown in the figure, and remove the intake manifold collector cover, gasket, intake manifold collector (lower) and gasket with power tool. INSPECTION AFTER REMOVAL Surface Distortion Check the surface distortion of both the intake manifold collector (upper and lower) mating surfaces with straightedge and feeler gauge. Limit : 0.1 mm (0.004 in) If it exceeds the limit, replace intake manifold collector (upper and/or lower). PBIC0774E PBIC0775E EM-20
INSTALLATION Note the following, and install in the reverse order of removal. Indication of Part Installation Direction Referring to front marks, install parts shown in the figure. A EM C D E F G Intake Manifold Collector (Lower) Tighten in numerical order as shown in the figure. NOTE: Tighten mounting bolts to secure gasket (lower), intake manifold collector (lower), gasket (upper), and intake manifold collector cover. PBIC0776E H I J K Intake Manifold Collector (Upper) If stud bolts were removed, install them and tighten to the torque specified below. Shank length under bolt head varies with bolt location. Install bolts while referring to numbers shown below and in the figure. (Bolt length does not include pilot portion.) Tighten in numerical order as shown in the figure. Water Hose : 4.9-6.9 N m (0.5-0.7 kg-m, 44-61 in-lb) Bolt M6 25 mm (0.98 in) : 7, 8, 10, 11, 13, 14, 15, 16, 18 M6 45 mm (1.77 in) : 2, 4, 5 M6 60 mm (2.36 in) : 1, 3, 6, 9 M6 Nut : 12, 17 Insert hose by 27 to 32 mm (1.06 to 1.26 in) from connector end. PBIC0774E PBIC0773E L M EM-21
Clamp hose at location of 3 to 7 mm (0.12 to 0.28 in) from hose end. Electric Throttle Control Actuator Install gasket with three protrusions for installation check facing any direction other than upward. Tighten in numerical order as shown in the figure. Perform the Throttle Valve Closed Position Learning when harness connector of electric throttle control actuator is disconnected. Refer to EC-42, "Throttle Valve Closed Position Learning". Perform the Idle Air Volume Learning and Throttle Valve Closed Position Learning when electric throttle control actuator is replaced. Refer to EC-42, "Idle Air Volume Learning". KBIA0957E EM-22
