Is the low coolant warning light on your dash stuck on, even though you know the radiator is full? On 2013-2018 Dodge Ram 2500, 3500, 4500, and 5500 trucks with the diesel engine, a faulty coolant reservoir level sensor is a common culprit. This is the exact replacement part (OEM number 68354536AA). It's a small sensor that sits in the side of the coolant overflow tank and tells your truck's computer how much coolant is in there. When it fails, it can trigger a false warning. Replacing it is usually pretty straightforward: locate the sensor on the reservoir, unplug the electrical connector, twist and pull the old one out, apply a little lubricant to the new one's seal, and push it in. Just be careful – it's a plastic part, so don't force it. Made from durable plastic to withstand the heat and chemicals in the cooling system. Fixing this gets that annoying warning light off your dash and ensures your truck's monitoring system is working correctly to protect your expensive diesel engine from overheating. A simple, vital maintenance part for keeping your Ram on the road.
