TD5 Oil Cooler Repair Kits for Defender & Discovery 2
TD5 oil cooler repair kits and complete PBC500230 housing assemblies for Defender and Discovery 2, including the OE Nissens cooler and Elring gasket kit for rebuilding a serviceable original housing.
Check the cast aluminium housing before ordering. A sound housing can be rebuilt with a new cooler, gaskets and sealing hardware; cracked castings, damaged threads or a damaged oil-pressure-switch port require the complete housing assembly.

Why use the Nissens and Elring kit?
The main distinction is the cooler itself. The kit combines an OE Nissens oil cooler with an Elring ERR7220 housing-to-block gasket, LVH100230 oil filter housing gasket, ERR7098 centrifugal filter housing O-ring, new banjo bolts and Dowty sealing washers. It provides the principal parts needed to rebuild a serviceable original housing around an OE cooler rather than a standard replacement cooler.
