104000 miles. Drained and filled the radiator with Toyota pink at 99,000 miles. Went to check under the hood today and noticed dried up pink residue on the left side of the engine. Same side as the serpentine belt and water pump. Some reside is above the level of the water pump but I assume if coolant seeps onto the belt it would get blown about the engine compartment. Coolant reservoir was a little low. Anything it could be besides a leaking water pump? Seems a bit early for a water pump to go in a Camry. What's the best way to confirm a leaking water pump?
