Hi all. I need assistance diagnosing a possible coolant leak. I found a wet spot underneath the car thinking it was oil. But the color and odor lead me to believe it is coolant. There is a small to medium amount of coolant on top of what I think is the thermostat housing. I’ve never had to work on this coolant leak but I want to be sure before I start working on it. Thanks
