2020 Bighorn with 5.7 L with 41K miles. I’ve had a distinct antifreeze smell with no obvious leaks the last few months. Temps and gauges have all been fine. Just a strong antifreeze smell. Read up on it and it seems others have as well. Reservoir tank shows acceptable level of coolant. Oil level is fine and looks normal in color and nothing mixed.
I did take off the radiator cap after the engine cooled and noticed a slight brown liquid but under it was the right red color. I checked under the radiator cap this morning with the truck just sitting overnight and there was more brown grainy liquid at the top. Put my finger in more and it looked more like antifreeze. Am I overthinking this or is the smell after I drive and the grainy light brown liquid under the cap a big issue?
