Lotus Service Notes
7. Release the radiator mounting panel from the crash structure and lift away the complete assembly.
8. To remove the radiator pack from the mounting panel, pull out the sealing foam, release the three bolts
securing each rear bracket to the panel, and the two bolts fixing each front bracket to the panel. Separate
the fans, condenser and radiator as necessary.
9. On re-assembly, note that the two angle brackets securing the rear of the condenser to the radiator duct,
are positioned below the condenser flange, and use a spacer washer at the adjacent fixing point to
replicate the flange thickness. Ensure that the sealing foam is refitted around the sides and rear of the
condenser, and that the spreader plates are fitted on top of the housing at the front fixing points.
10. - If a new condenser is fitted, add 30 cm³ of approved refrigerant oil to the system.
- Use new 'O' rings on the pipe connections, and lubricate with refrigerant oil.
- Using two spanners, tighten the condenser inlet connection to 25 - 30 Nm.
- Using two spanners, tighten the condenser outlet connection to 20 - 25 Nm.
- Recharge the system with 0.55 kg of R134a.
- Refill the cooling system (see sub-section KH.3).
PL.9 - RECEIVER-DRIER
If the system has been open to at-
mosphere for any length of time, e.g. fol-
lowing accident damage or a burst hose or
damaged component, the receiver-drier
unit must be renewed, and should be the
last component to be fitted, and uncapped
only immediately prior to connection and
recharging.
The receiver-drier is clamped to a
mounting bracket at the front of the climate
chamber. If the receiver-drier is to be re-
placed, the refrigerant must first be recov-
ered using suitable equipment connected
to the service ports at the right hand front
of the engine bay.
- Cap all pipes and ports immediately
after disconnection to prevent the in-
gress of dirt and moisture.
- When reconnecting the pipes, use
new 'O' rings coated in an approved
refrigerant oil, and tighten to 20 - 25
Nm.
PL.10 - EXPANSION VALVE
The expansion valve is fitted onto the evaporator inlet and outlet pipes above the climate chamber, and
is accessible from within the front services compartment. To replace the valve:
1. Recover the refrigerant using suitable equipment connected to the service ports at the right hand front of
the engine bay.
2. Release the single M6 screw securing the clamp plate to the top of the expansion valve, and withdraw the
plate and both pipes from the valve. Immediately cap the pipes and ports to prevent the ingress of dirt
and moisture.
