The cooling
pack incorporates the radiator a
ssembly with integral transmission oil cool er (located in the radiator outlet tank),
an air conditioning condenser, and the cooling fans and cowl assembly.
The cooling pack on supercharged vehicles is the same as described above, but with the addition of a charge air cooler
coolant radiator located in front of the condenser.
Radiator Mounti
ng/Retention
T
he radiator is mounted on four rubber mounts, one on each
end of the upper and lower horizontal face. The two lower
mountings are supported on two isolated brackets mounted on the body; the lower cradle assembly has subsequently been
deleted.
A closing panel made from polypropylene, which retains the radiat or assembly, fits over the top of the radiator and is bolted
to the vehicle top panel.

NOTE: During cranking with the engine disabled, observe the engine cranking speed. A cranking speed as low as 90 rpm
is acceptable, but will be difficult to measure. A degree of discretion must be used as to when an engine is cranking too
slowly.

T
he canisters are fixed to the underside of the vehicle either
directly or via semi-enclosed mounting brackets. Two fixing
bolts are used at the front of the canister(or bracket) and a single rear bolt supports the canister and the canister close
valve (CCV).
The vapour pipes to the canisters, other than the CCV, use multi-tang connectors which are push fitted and pulled out
without the use of tools.
The canister close valve has a stub pipe with 'O' ring seal wh ich is a simple push fit into the canister. A mounting bracket on
the canister close valve enables it to be secured to the underbody via the canister rear mounting bolt.
A hose connects the CCV to the bracket mounted adaptor into which the vent system air filter is screwed.
