Dearfield Co. | Well after owning a bunch of low flow cooling trucks I will state yes the radiator needs kept clean and chemical levels checked but thats every diesel engine not just big cam cummins.The only issue I ever had with any of the low flow motors is thermostats and fuel issues on the 444.They only had a dozen or so updates on inj in the first 2 years in the life of this engine.the thermostat issue is unpredictable and all my trucks carried a set when we ran them.I think the 444 and 365 were way better engines than the early big cam 1 engines that had worse issues with the odd head bolts and paper thin cam bearings | |
