Brown Sludge on Coolant Dipstick?

[Gearhead54]

I totally agree with your desire to have the coolant flushed. Should be part of the service for fixing the issue

Also, the part that was replace doesn't have any extra warranty.. not even a year for this replacement. When my powertrain warranty ends in April, so does the warranty for this new oil cooler...

I just got off the phone with the service advisor. Tech did a pressure test and found that the oil cooler failed allowing oil to get into the coolant and radiator. He said they ordered a new radiator, oil cooler and all hoses to replace.

He said the oil coolers fail on the 2019’s frequently due to the design. He said Ram changed the design starting 2021 and that I will be getting the new design.

Do you have a part number for the new design? I'd like to swap mine out before it causes problems.
