Saturn L 200 and the antifreeze was under floor mat passenger side of your car what would this be?

Finding antifreeze under the passenger-side floor mat of a Saturn L200 suggests a leak in the cooling system. The most likely culprit is a leak in the heater core. The heater core is located inside the passenger compartment, and a leak there would allow antifreeze to drip onto the floor.

However, it's crucial to note: This is just a likely scenario. Other possibilities, though less probable, include:

* A leak in a hose: While less likely to pool directly under the mat, a small crack or hole in a hose near the passenger side could eventually lead to a spill.

* A damaged water pump: A failing water pump could leak coolant, but it's less likely to specifically end up under the passenger mat.

* A compromised radiator: Similar to the water pump, a radiator leak is usually more noticeable and wouldn't necessarily drip specifically under the passenger mat.

You should NOT drive the car until the leak is identified and repaired. Antifreeze is toxic, and continuing to drive with a leak could lead to overheating and potentially serious engine damage. You should have a mechanic inspect your Saturn L200 as soon as possible.
