SDEC Oil Cooler

Oil cooler and gasket parts for SDEC diesel engines operating in hot oilfield and construction environments. This listing spans four separate engine platforms — the 6.44 L SC7H, the 8.82 L SC9D, the 10.5 L SC11CB and the 12.88 L SC13G — and core size scales with the engine, so nothing crosses between series. Most enquiries that reach us as oil cooler turn out to need the housing gasket set and O-rings rather than a complete assembly; those are the parts that fail and they cost a fraction of a core. The distinction that matters is where the oil is going: an external weep is usually gaskets, while oil found in the coolant or coolant in the oil means the core itself has failed. Tell us which you are seeing.
