Now it seems to be leaking a lot again I'm not gunning it or slamming on the gas at all Maybe once in a while. We looked at five components in a cummins engine that could cause coolant loss with no leaks These issues include cylinder head crack, defective water pump, and head gasket problems Natural evaporation and blocked radiators can also cause this issue
White smoke, overheating, and warning light are symptoms of coolant loss outside of leaks. My 6.7 is losing coolant, with no visible leaks Replace thermostat, still didn't help Oil looks good, doesn't white smoke, pressurized the coolant system all was good, head gasket looks good If you notice your coolant reservoir empty, you'd expect a puddle under your car But what does it mean if you're losing coolant yet don't see a leak?
Be sure to check your coolant levels on a regular basis and top off when necessary until you discover and fix the source of the leak. Well, pressure tested coolant system Pressure stayed steady on both and once again no leaks could be found I’m now at a complete loss 🤔 2007.5 ram 3500 6.7, 853,000mi as of 11/24.
