if it's a bad leak, look with a trouble light. start on the floor, then go straight up from there. try to trace it to the source. otherwise, mechanics use a pressure tester to pump up the system while engine is cool. not exactly a cheap tool and some work far better than others. ( i have one and it's a piece of crap compared to others I've used) don't forget to check the floor under your dash in case your heater core is leaking. if you never see any leaks but you keep having to add coolant, the coolant is going inside your engine, either getting burned with the fuel or it's in the oil. but boy i hope not. check the oil, doesn't look like a chocolate shake does it? as far as fixing, it depends on what's leaking.

Adding pepper to the cooling system can work at times. It is in no way a sure fire way of stopping a leak, and is definitely not a long term fix or even a good idea.Adding pepper to the cooling system can work at times.
