7 Bleed pipe connection (containing check valve) The body of the coolant pump contains an impeller attached to a shaft supported in a bearing assembly. The impeller is driven
by a pulley, pressed on to the front of the shaft, which is driven by the accessory drive belt. For additional information, refer to
303-05E Accessory Drive - 5.0L, Vehicles Without: Supercharger or 303-05F - 5.0L, Vehicles With: Supercharger.

Two coolant outlet flanges attach the coolant pump to the front of the cylinder heads. A pipe connects a further coolant outlet
to a pipe from the engine oil cooler. A bleed connector is installed in the front of the coolant pump, adjacent to the coolant
inlet connection from the thermostat. A check valve is incorporated into the bleed connection.

THERMOSTAT



Item Description 1 Screw (3 off) 2 Lower body 3 Upper body 4 Thermostat 5 Seal The thermostat is a multi-stage device located in the coolant pump inlet to provide fast response and control of the engine
outlet temperature.

The thermostat allows rapid engine warm-up by preventing coolant flow through the radiator and by limiting coolant flow
through the cylinder block when the engine is cold. During warm-up and at engines speeds above approximately 1800 rev/min,
a by-pass valve opens to control the coolant flow and pressure, to protect the engine components. When the thermostat
opening reaches 6 mm (0.24 in.), the by-pass flow is shut-off. When the thermostat opening exceeds 6 mm (0.24 in.), the
radiator coolant flow is further controlled up to the point where the thermostat is fully open. At this point maximum radiator
coolant flow is achieved to provide maximum cooling.

On both naturally aspirated and supercharger vehicles, the thermostat begins to open at 88 - 90 °C (190 - 194 °F) and is fully
open at 102 °C (216 °F).

The SC is a Roots blower with high angle helix rotors driven at 2.1 x engine speed by the secondary belt of the accessory drive.
The two rotors of the SC are contained in a housing. The ends of the rotors are supported in bearings in the front cover and the bearing plate. A rear cover seals the bearing plate and incorporates a filler/level plug for lubricant. A pulley transfers power
from the accessory drive to the shaft of one of the rotors.

A pneumatic actuator on the front cover is attached to a by-pass valve in the housing. The bypass valve regulates a flow of air
from the outlet of the SC back to the inlet side of the rotors, to control the outlet pressure of the SC. Hoses connect the pneumatic actuator to the throttle T-piece of the air ducts, upstream of the electric throttle, and to the front cover, downstream
of the electric throttle. A lever connects the actuating rod of the pneumatic actuator to the shaft of the bypass
valve. A screw in the front cover limits movement of the lever in the closed direction to allow calibration of the SC output. The front cover also incorporates:

The SC air inlet and mounting face for the electric throttle. A connector stub for the part load breather.
A MAP (manifold absolute pressure) sensor.
A connector stub for a hose from the EVAP (evaporative emission) canister purge valve.
Intake Manifolds

Each intake manifold is attached to the SC with three screws and a bolt. Two dowels ensure correct alignment of each intake manifold. The RHD (right-hand drive) intake manifold incorporates a connection port for the noise feedback system. The LH intake manifold incorporates:
A connector stub for the brake vacuum system.
A MAPT (manifold absolute pressure and temperature) sensor.

1 Sprags 2 Inner race 3 Outer race 4 Sprag and cage assembly 5 Sprag outer race 6 Sprag inner race 7 Retaining ring The free wheel clutch can perform three functions; hold the stator stationary, drive the stator and free wheel allowing the
stator to rotate without a drive output. The free wheel clutch used in the ZF 6HP28 transmission is of the sprag type and
comprises an inner and outer race and a sprag and cage assembly. The inner and outer races are pressed into their related
components with which they rotate. The sprag and cage assembly is located between the inner and outer races.

The sprags are located in a cage which is a spring which holds the sprags in the 'wedge' direction and maintains them in
contact with the inner and outer races.

Referring to the illustration, the sprags are designed so that the dimension 'B' is larger than the distance between the inner
and outer race bearing surfaces. When the outer race rotates in a clockwise direction, the sprags twist and the edges across
the dimension 'B' wedge between the races, providing a positive drive through each sprag to the inner race. The dimension 'A'
is smaller than the distance between the inner and outer race bearing surfaces. When the outer race rotates in an
anti-clockwise direction, the dimension 'A' is too small to allow the sprags to wedge between the races, allowing the outer
race to rotate freely.

On the illustration shown, when the outer race is rotated in a clockwise direction, the sprags twist and are 'wedged' between
the inner and outer races. The sprags then transfer the rotation of the outer race to the inner race, which rotates at the same
speed.

Lock-Up Clutch Mechanism

The TCC (torque converter clutch) is hydraulically controlled by an EPRS, which is controlled by the TCM. This allows the torque converter to have three states of operation as follows:
• Fully engaged
• Controlled slip variable engagement
• Fully disengaged.

The TCC is controlled by two hydraulic spool valves located in the valve block. These valves are actuated by pilot pressure supplied via a solenoid valve which is also located in the valve block. The solenoid valve is operated by PWM (pulse width One Way Free Wheel Clutch – Typical

1 Securing ring 2 Shaft oil seal 3 O-ring seal 4 Pump housing 5 Ring gear 6 Crescent spacer 7 Roller bearing 8 Impeller 9 Centering pin 10 Spring washer 11 Outlet port (high pressure) 12 Inlet port (low pressure) The pump comprises a housing, a crescent spacer, an impeller and a ring gear. The housing has inlet and outlet ports to direct
flow and is located in the intermediate plate by a centering pin. The pump action is achieved by the impeller, ring gear and
crescent spacer.

The crescent spacer is fixed in its position by a pin and is located between the ring gear and the impeller. The impeller is
driven by drive from the torque converter hub which is located on a needle roller bearing in the pump housing. The impeller
teeth mesh with those of the ring gear. When the impeller is rotated, the motion is transferred to the ring gear which rotates
in the same direction.

The rotational motion of the ring gear and the impeller collects fluid from the intake port in the spaces between the teeth.
When the teeth reach the crescent spacer, the oil is trapped in the spaces between the teeth and is carried with the rotation
of the gears. The spacer tapers near the outlet port. This reduces the space between the gear teeth causing a build up of fluid
pressure as the oil reaches the outlet port. When the teeth pass the end of the spacer the pressurized fluid is released into
the outlet port.

The fluid emerging from the outlet port is passed through the fluid pressure control valve. At high operating speeds the
pressure control valve maintains the output pressure to the gearbox at a predetermined maximum level. Excess fluid is
relieved from the pressure control valve and is directed, via the main pressure valve in the valve block, back to the pump inlet
port. This provides a pressurized feed to the pump inlet which prevents cavitation and reduces pump noise.

DRIVE CLUTCHES



Item Description 1 Input shaft 2 Main pressure supply port 3 Piston 4 Cylinder – external plate carrier 5 Clutch plate assembly 6 Baffle plate 7 Diaphragm spring 8 Output shaft 9 Bearing 10 Dynamic pressure equalization chamber 11 Piston chamber 12 Lubrication channel There are three drive clutches and two brake clutches used in the ZF 6HP28 transmission. Each clutch comprises one or more
friction plates dependent on the output controlled. A typical clutch consists of a number of steel outer plates and inner plates
with friction material bonded to each face.

On 5.0L SC (supercharger) and 3.0L diesel models, the uprated transmission includes additional clutch plates to enable the
transmission to manage the additional power output from these engines.

The clutch plates are held apart mechanically by a diaphragm spring and hydraulically by dynamic pressure. The pressure is
derived from a lubrication channel which supplies fluid to the bearings etc. The fluid is passed via a drilling in the output shaft
into the chamber between the baffle plate and the piston. To prevent inadvertent clutch application due to pressure build up
produced by centrifugal force, the fluid in the dynamic pressure equalization chamber overcomes any pressure in the piston
chamber and holds the piston off the clutch plate assembly.

When clutch application is required, main pressure from the fluid pump is applied to the piston chamber from the supply port.
This main pressure overcomes the low pressure fluid present in the dynamic pressure equalization chamber. The piston moves,
against the pressure applied by the diaphragm spring, and compresses the clutch plate assembly. When the main pressure
falls, the diaphragm spring pushes the piston away from the clutch plate assembly, disengaging the clutch.

PLANETARY GEAR TRAINS

The planetary gear trains used on the ZF 6HP28 transmission comprise a single web planetary gear train and a double web
planetary gear train. These gear trains are known as Lepelletier type gear trains and together produce the six forward gears
and the one reverse gear.

Single Web Planetary Gear Train
The single web planetary gear train comprises:

Body Repairs - Water Leaks - Water Leaks
Description and Operation

General Published: 11-May-2011

If water leaks occur after bodywork repairs, the cause can be established using the checks described below. A
systematic and logical procedure is required to locate water leaks. Before beginning extensive checks, a thorough visual
inspection must be carried out.
Visual Inspection
- The following characteristics may indicate existing leaks:
- Check the clearance and accurate fit of ancillary components such as the hood, tailgate, liftgate, doors, and so
on.
- Check for correct fit and possible damage to sealing elements such as blanking plugs, rubber door seals, and so
on.
- Check water drain holes for unhindered flow.
Various tests can be used to provide further information on possible leaks:
- Water test
- Washer test
- Road test
- Chalk (powder) test

Practical execution of tests and checks

Water test


NOTE: Never aim a jet of water directly at a rubber seal.

Carry out the water test with a second person present (in the passenger compartment).
Use variable washer nozzles (concentrated water jet to fine spray mist).
Start in the lower section and spray the whole area, working upwards in stages.

Washer test

Further tests can be carried out in the washer system.
Some leaks originate here, or only occur here.
The relevant passenger compartment should be checked using a torch during the wash procedure.
Road test

If no leaks are located during the tests above, road tests should be carried out on wet roads.
Road tests under various conditions:
- At various speeds.
- On various road surfaces (asphalt to cobbles).
- With loaded or unloaded vehicle.
- Driving through puddles (splash water).

Chalk test (powder test)

In this test, the clamping load and the bearing surface of the seal are checked.
Performing the test:
- Dust the door seal with powder or coat with chalk.
- Coat the bearing surface of the seal with a thin film of Vaseline.
- Slowly close the door and open it again.
- Check the width and continuity of the imprint on the door seal.

Other test equipment

Other equipment such as stethoscopes, UV lamps, special mirrors or ultrasound measuring instruments can be used to
locate leaks.

Rectifying the leak using recommended tools, auxiliary equipment and materials

Tools and auxiliary equipment:
- Dry, absorbent cloths
- Variable washer nozzle
- Torch, fluorescent tube
- Mirror
- Compressed air
- Seal lip installer
- Wet/dry vacuum cleaner
- Sealing compound compressor
- Remover for interior trim
- Cutter blade or pocket knife
- Wedge (wood or plastic)
- Hot air blower
- Special mirror for concealed leaks

Side windows

In the case of side windows, the same problems can arise as for a windscreen. The same corrective actions must therefore be
used.
Door seal

Diagnosis:
- Water ingress in the lower part of the interior door trim or in the rocker panel area.
Cause:
- The water shield fitted behind the interior door trim exists to drain off water that has entered the door via the
drainage holes, either downwards or outwards. If the water shield seal is damaged or has been fitted incorrectly,
then water can get into the passenger compartment.
- In addition to this, the drainage holes can become clogged with leaves, dirt or excess cavity protection agents.
Water gathers in the door and ingresses into the passenger compartment.
- Check water shield for damage or correct fitting.
- If the water shield needs to be re-bonded, then approved seam sealer should be used.
- Before the water shield is installed, the drainage holes must be checked for unhindered flow.
Door seals

Diagnosis:
- Ingress of water into the rocker panel area
Cause:
- Insufficient clamping load between seal and door.
Corrective action:

NOTE: When adjusting the clamping load, the profile alignment of the relevant components must always be taken
into consideration.


NOTE: Do not realign the flange too far in the direction of the door, as this can reduce the bearing surface of the
seal to the door.
- Check clamping load:
- The easiest way to check the clamping load of a seal to the respective bearing surface is by means of a paper
strip test. This consists of trapping strips of paper at various points between the door and the seal, and fully
closing the door. If it is possible to pull out the paper with no great resistance, then the clamping load is too
low.
- Adjust the clamping load:
- The clamping load is normally adjusted using the striker. When doing so, the edge alignment from the door to
the side panel, or from the front door to the rear door must be taken into account.
- Another setting method is to realign the panel flange for the seal mounting. The clamping load is increased by
moving the flange towards the door.
- Check the bearing surface:
- Apply chalk evenly to the surface of the seal. Evenly coat the bearing surface of the door with Vaseline.
- Close the door fully, the lock must engage. Open the door. The imprint of the chalk (bearing surface) can be
identified in the film of Vaseline.
- The bearing surface should be at least 5mm across at all points.

Other causes:
- The door seal must completely seal the door where it meets the bodywork.
- Water can ingress directly or indirectly into the interior of the vehicle if the seal is damaged at any point.
Corrective action:
- A damaged or worn door seal must always be renewed in full.
- When renewing the seal, the following must be taken into account:
- Always fit the seal first in the area of the narrow radii (corner points).
- Next, secure the seal to the flange evenly by tapping lightly with a rubber hammer. The installed seal must not
be kinked at any point.

NOTE: The prescribed length of a seal must not be shortened.
Other cause:
- The door seal is attached to the welded flange all the way round. If this welded flange is uneven or damaged at
any point (usually in areas with small radii) then this point could be subject to leaks.
- A stretched seal carrier can also cause a leak.
- In both cases, water gets into the vehicle interior under the seal carrier.
Corrective action:
- Align the deformed welded flange using a hammer and anvil block, prevent and, if necessary, repair any paint
damage.
Sliding roof/tilting roof

Diagnosis:
- Ingress of water at sliding roof aperture
Cause:
- The sliding roof/tilting roof is installed in a water trap. The water drains off via the water trap, water drain holes
and drain hoses. The drain hoses lead downwards on both sides via the A-pillar and B-pillar.
- The drain holes or drain hoses can become clogged with leaves, dirt, underbody protection and so on.
Corrective action:
