My car has been losing coolant and I couldn't find a leak untill I pulled up my passanger's side carpet and found small pools of coolant>>>
Is this happening in the 03? As everyone has already stated, sounds like the heater core... but odd that a heater core would go bad in an 03 w/ only 40k miles.
The heater core just went in my dads truck the other day and dumped coolant on the passenger side floorboard. But, uh, it's a 97 w/ 200k miles. Since he doesn't need the heater, we just cut the hoses and rerouted them back into the engine.
