Oil cooler Volvo B230ET/FT (-1987)

Oil leaks around the filter housing or rising oil temperature on a hard-driven turbo can point to tired seals in the oil cooler circuit. On the Volvo 740/760/780 with B230ET/FT up to 1987, the oil cooler works against considerably higher heat loads than the naturally aspirated engines, which makes O-rings and washers common check points during service.

This category gathers parts for the oil cooler circuit on these specific turbo engines. The group includes oil filters, washers, O-rings, coupling nuts and cones – components that are often replaced at the same time once the connections have been opened. Since the fit is governed by the engine code and the model year (-1987), the chassis number and code should be verified before ordering, so that seals and nuts match the correct version.
