Removal and Installation

Removal


NOTE: Removal steps in this procedure may contain installation details.

1. Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).

2. Refer to: Air Conditioning (A/C) System Recovery, Evacuation and Charging (412-00 Climate Control System - General Information, General Procedures).


3. WARNING: Make sure to support the vehicle with axle stands.
Raise and support the vehicle.


4. NOTE: Some variation in the illustrations may occur, but
the essential information is always correct.


























5. WARNINGS:


Since injury such as scalding could be caused by escaping steam or
coolant, do not remove the filler cap from the coolant expansion tank
while the system is hot.


Be prepared to catch escaping fluid.

CAUTION: Be prepared to collect escaping coolant.

1 Pipe clip bracket (2 off) 2 Coolant outlet connection 3 Lower attachment bracket (2 off) 4 Coolant inlet connection 5 Upper attachment bracket (2 off) 6 Expansion hose connection (with engine cooling system) The charge air radiator is a cross flow type with an aluminum core and plastic end tanks. The charge air radiator is installed in
the cooling module, in front of the A/C (air conditioning) condenser. Brackets on the end tanks attach the charge air radiator to
the front of the engine cooling system radiator.

The RH end tank incorporates the coolant inlet and outlet connections, and a connection for the hose to the engine cooling system. Hoses connect the inlet of the charge air radiator to the charge air coolers, and the outlet to the charge air coolant
pump.

CHARGE AIR COOLERS

A charge air cooler is installed in each intake manifold.
Refer to: Intake Air Distribution and Filtering (303-12C Intake Air Distribution and Filtering - V8 5.0L Petrol, Description and Operation). CHARGE AIR RADIATOR

Accessory Drive - V8 S/C 5.0L Petrol - Accessory Drive - Overview
Description and Operation

OVERVIEW

The accessory drive is a belt system powered by a pulley attached to the front of the crankshaft. The crankshaft pulley, which
incorporates a torsional vibration damper, drives two drive belts. An automatic belt tensioner in each belt run maintains the
drive belt at the correct tension. Together with idler pulleys, the belt tensioners also guide the drive belts clear of obstructions
and set the correct 'wrap-around' of the accessory component drive pulleys to ensure a slip-free drive.

PRIMARY DRIVE BELT
The primary drive belt is a six-ribbed poly-V belt that drives the:
Coolant pump
Power steering pump
A/C (air conditioning) compressor
Generator.

SECONDARY DRIVE BELT

The secondary drive belt is an eight-ribbed poly-V belt that drives the SC (supercharger).

BELT TENSIONERS

Each belt tensioner consists of an idler pulley on the end of a spring loaded pivot arm. The pivot arms can be turned manually
for removal and installation of the drive belts.
Each belt tensioners is calibrated to automatically maintain the correct tension in the related drive belt.

NOTE: ROW vehicles.

Description Specification Air conditioning (A/C) refrigerant R-134a A/C compressor oil SPA2
NOTE: EU vehicles.

Description Specification Air conditioning (A/C) refrigerant R-1234yf A/C compressor oil SPA2 Capacities
Description Grammes A/C refrigerant - all engine variants 700 Refrigerant Oil Adding Capacities

NOTE: Rotate the A/C compressor shaft at least 6 to 8 turns when draining the refrigerant oil.

Item Milliliters A/C condenser core and desiccant bag Add 25ml oil A/C evaporator Add 30ml oil A/C compressor
1. Drain old A/C compressor. With drain plug removed and ports uncapped, rotate
shaft to remove A/C compressor oil and measure the amount of oil captured. 2. Drain
new A/C compressor into a clean vessel. With drain plug removed and ports
uncapped, rotate shaft to remove oil. Then add back a quantity of the new oil that is
identical to the quantity of oil removed from the old A/C compressor. However, if this quantity is less than 30ml, then make it up to 30ml. A/C lines - if air conditioning has been operational. Add 5ml oil per A/C line A/C system after flushing - with new compressor installed No oil should be used- new oil in new compressor is sufficient A/C system after flushing - without a
new compressor installed - remaining
A/C compressor oil is to be drained.
Compressor and expansion valve must
not be flushed (removed from the circuit) Add 80ml oil A/C compressor drain plug Torque 12Nm www.JagDocs.com

Inspection and Verification


WARNING: Servicing must be carried out by personnel familiar with both vehicle system and the charging and testing
equipment. All operations must be carried out in a well ventilated area away from open flame and heat sources.


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern

2. Visually inspect for obvious signs of damage and system integrity
