Condition
Some customers may comment on a coolant leak. Upon investigation, the technician may find that the leaks appears to be coming from the lower radiator tank near the lower hose outlet.
Cause
The cooling system may experience increased internal pressures during sustained high RPMs at elevated operating temperatures. This increased pressure may cause a weakening of the core-to-tank mating surface.
Correction
Replace the radiator with a redesigned radiator, P/N 19129908. Refer to the Radiator Replacement (LS6) procedure in the Engine Cooling sub-section of the Service Manual (SI Document ID 1389672).
