International Engine >> INCORRECT THERMOSTAT ON 6.9L DIESELS
Caution On Using Correct Thermostat On
International 6.9L Diesel Engine Including
Those In Ford Vehicles
International Trucks reports that thermostats in 6.9L diesel
engines are being replaced with will fit replacements, which
may cause premature cylinder head gasket failure due to engine
overheating. The overheating occurs because a flat washer
secured to the end of the power pill obstructs the bypass and
normal coolant flow passage. See illustrations below.
