DEVICE FOR HEATING THE INLET AIR
It consists of the following
A - A vacuum capsule situated at the air-filter intake
B A thermal sensor, situated in the duct linking the air-filter to the carburettor
C - A,device for heatinq the inlet air by means of the exhaust (by having a take-off on the exhaust manifold shield). ASSEMBLY DIAGRAM

to air filter
Situated at the air-filter inlet. the vacuum capsule controls a flap and a closing plate allowing simultaneously supply
or no supply of warm air and no supply or supply of cold air. When starting ( Diagram 1 ) the capsule is subjected to
vacuum, the flap stops the supply of cold air, and the closing plate allows the supply of warm air to the air filter.
When the effect of the vacuum ceases, the capsule returns to length Ll ( Diagram 2 ) : the flap.opens, allowing supply
of cold air and the closing plate stops the supp[y of warm air.
The vacuum capsule operates via a thermal sensor.

This is situated in the duct linking the air filter to the carburettor ( see diagram below ).
__
Depending on the temperature of the inlet air. it allows or not vacuum to reach the control capsule for the flap and
the closing plate.
It consists of a number of valves and bi-metallic strips.
To inlet manifoldb-yTu-4
I To vacuum capsule Operating principle :
For an inlet air temperature below 6’ C, the position of the bi-metallic strips and the valves is such that vacuum in
the inlet manifold is communicated to the capsule (see para. A, diagram No. 1 )
For an inlet air temperature above 19” C, the bi-metallic strips change shape. and the position of the valves stops
the vacuum from reaching the capsule ( see para A. diagram No.2 ).
For an inlet air temperature between 6 and 19” C, the positions of valves and bi-metallic strips allow the action of
the vacuum on the capsule to be regulated. In this case, the flap and the closing plate are in an intermediate position,
allowing simultaneous supply of warm and cold air.

This device entails modifying the following components
- Heater distribution box ( outlets towards side vents unplugged, different radiator )
Side vents with twin outlets ( ambient or heated air )
Addition of Westaflex ducts ( link from heater distribution box to side vents ). III. WATER TEMPERATURE GAUGE
The presence of a water temperature gauge entails modifying the following components :
- water pump spacer ( addition of a temperature sensor )
steerinq column surround ( location of temperature gauqe )
- engine harness for warning lamp senders ( addition of lead from temperature sensor to front wiring harness )
addition of a temperature sensor and a temperature gauge.

1. Longitudinal adiustment :
Check
the clearance of the front door with the
front wing and the rear door : J=6+_3mm
If necessary. add or withdraw the adjustment shims
( thickness 1 or 2 mm ) at <( a 1) and << b to_ a) Fitting shims at SC a u :
Remove screw (2) and loosen the 2 screws ( 1).
Slide the shims between hody and hinge.
Fit screw (2) and tighten the three fixing
nuts of upper hinge.
b) Fitting shims at <, b n :
Remove the two fixing screws (4) for distance
strop (3) and tilt it.
Loosen the two screws (5 ).
Slide the shims between body &hinge and
retighten fixing screws (5 ). 2. Transversal and height adjustments :
Loosen hinge fixing screws.
Move the door vertically in order to obtain a
clearance of : Jl = 7 +‘2mm
between the upper port of the window frame and
the roof edging.
Check ‘the continuity of the a light line 1) and
the difference in alignment between door and
front wing. Inset of front door in relation to
front wing = maximum of 2 mm.
Tighten the hinge fixing SCWNS and fix door
check (3) using screws (“4). 3. Adjustment of door striking plate engagement :
Loosen. the two door striking plate fixing screws
and adjust the plate so that correct locking and
sufficient compression of the door rubber sealing
strips is obtained.
If necessary, fit shims at (cc )P.
The rear edge of the front door must not stand
proud by more than 2 mm with respect to the front
edge of the rear door.
Tighten the screws (6 ).
