Alfa 145/146 Boxer air conditioning compressor union. This is the alternator/AC compressor union for the Alfa 145/146 Boxer models. This union can also be fitted to the Alfa 33 models by adding a 6 mm spacer/washer on the alternator mounting lug (green circle on diagram).
OEM part number is 60588397.
Due to the alloy material that the union is made of, it usually corrodes from the electrolysis which occurs in the cooling system. Signs of deterioration are leaks from the hose connections or blobs where coolant passes through, which once pressed or pried will result in coolant leak.
Suitable for Alfa 145/146 boxer models but also easily adaptable to Alfa 33 AC equipped models by adding a spacer of 6mm on the alternator mounting lug.
