Vertically mounted intercooler
To remove
1 Release the hose clips (A7) which fasten the air
hose from the turbocharger to the intercooler. Slide
the hose away from the intercooler air inlet pipe.
Warning! Do not drain the coolant while the engine
is still hot and the system is under pressure because
dangerous hot coolant can be discharged.
2 Drain the coolant system and release the hose clips
(A5) which fasten the hoses to the coolant inlet and
the outlet connections of the tube stack. Remove the
hoses.
3 If a fuelled starting aid (A8) is fitted to the top cover
(A4), remove the electrical connection and the fuel
pipe.
Caution: Do not use a lever between the flange
faces to separate the intercooler top cover from the
induction manifold.
4 Release the setscrews (A2) which retain the
intercooler cover to the induction manifold (A6); work
from the outside of the flange to the centre. Remove
the top cover and discard the joint.
Caution: Be careful with the tubestack (A9) when it
is removed and fitted, be especially careful not to
damage the fins.
5 Remove the four setscrews (A1), six cylinder
engines have six setscrews, that secure the
tubestack to the induction manifold.
6 Carefully lift the tubestack from the induction
manifold, Do not use force. It may be necessary to
push the inlet and outlet connections from the outside
of the manifold to fully release the tubestack. Remove
and discard the "O" rings (A3) for the inlet and outlet
connections.
