Lotus Service Notes
PL.8 - CONDENSER
The engine cooling radiator, a.c. condenser and cooling fans are secured together as a package and are
mounted horizontally, with fans lowermost, on top of the crash structure. The all aluminium condenser is of
parallel flow construction, with tanks at each side which direct the refrigerant flow from the front inlet connec-
tion successively through 10, 7, 5 and 4 rows, before it emerges from the rear outlet union. Bonded to the front
and rear of the condenser are steel channels which incorporate mounting brackets to attach the unit to the
lower flanges of the engine cooling radiator, and also to provide mountings for the two cooling fans.
For access to the condenser or cooling fans, the front clamshell must be removed followed by the radiator
mounting panel with the complete cooling pack.
1. Remove the front clamshell (see sub-section BR.6).
2. Remove the two air deflector/water shields.
3. Drain the coolant and disconnect the feed and return hoses from the radiator.
4. Unplug the fan harness connector(s).
5. Recover the refrigerant using suitable equipment connected to the service ports at the right hand front of
the engine bay.
6. Using two spanners on each connection to avoid twisting the union, release the two refrigerant pipes from
the condenser and immediately cap both the pipes and the condenser unions to prevent the ingress of dirt
and moisture.
