Q&A Section

Q1: How can I tell if my 101-1741 oil cooler has failed?

A: The most common sign is "oil in the coolant" or "coolant in the oil." If the internal core leaks, the higher-pressure oil usually forces its way into the cooling system, resulting in a milky residue in the radiator or expansion tank.

Q2: Should I repair or replace a leaking oil cooler on a D9?

A: While some specialty shops can "boil out" or patch a cooler, it is generally recommended to replace the unit. A failure in the 101-1741 can lead to contaminated oil, which can destroy the main bearings of a multi-thousand-dollar engine or transmission.

Q3: Does the 101-1741 come with the necessary seal kit?

A: This varies by supplier. However, because the oil cooler must be pressure-sealed against the engine block or housing, it is critical to use new CAT-spec O-rings and gaskets during the installation of the 101-1741.
