On turbocharged (T) and turbocharged and aftercooled (TA) engines with radiators, install the temperature shutoff contactor in Location (A).2. On T and TA engines with radiators, use the 7W2967 Adapter (see Illustrations 2 and 3) and install the temperature prealarm contactor group in Location (D).3. Use Locations (B), (C), and (E) in the cylinder heads, for other, smaller temperature protection devices. On engines equipped with aftercoolers, the aftercooler water inlet tube must be removed and reinstalled so that these water temperature protection devices can be installed in Locations (B), (C) and (E).
