The securing bolts of the condenser are difficult to access. With
the aid of a second mechanic, lift the charge air cooler out of the
radiator mountings. The charge air cooler can now be moved
»back and forth« to allow access to the securing bolts.
– Unbolt condenser from charge air cooler -arrows-.
– Attach condenser to lock carrier using cable ties.
– Take out charge air cooler from underneath.
Installing:
Installation is carried out in the reverse order. When installing,
note the following:
♦ Hose connections and hoses for charge air system must be
free of oil and grease before assembly. The seal and sealing
surface must be oiled lightly only for plug-in connectors
