Important Repair Hints
If the pressure relief valve is removed, always replace the aluminum sealing ring, PN N 043 815 3 and install a new O-ring.
For valve PN 944 107 035 11 use O-ring PN 944 107 935 11.
For valve PN 944 107 035 01 use O-ring PN 944 107 935 01.
Coat the relief valve O-ring and outer surface with oil to prevent binding during installation.
It is imperative that the oil cooler housing and the oil pressure relief valve bore in the engine block be perfectly aligned. If they are not, the oil pressure

one-piece pressure relief valve will cause the valve to come apart. If this occurs, the valve must not be reassembled and used. Instead, a new valve should
be installed. This unit is considered a NON-serviceable part and must not be disassembled.
Alignment of the pressure relief valve bore is accomplished by using the following tools:
