I have a Mazda 3 SP 23 2005 _ manual _ 2.0 Liter unleaded.
I have noticed that some cooling liquid started leaking on my parking spot a week ago. The leaking stains are becoming bigger day after day. It's mostly coming from the right side when you are facing the engine. I had a quick chat with one mechanic which believes it could be coming from the thermostat. He told me to refill the cooling liquid tank with some water before I fix the problem. Does anyone have any idea what the leak could come from? I don't know anything about cars, I want to resolve the problems ASAP but I don't want to be ripped off. Thank you in advance for your help Regards Sylvain
