Just recently had my car checked out and the mechanic used a pressure system to see where I was leaking from. The only place he found was some type of "plug" that he fixed and right now there isn't any leaking. My heater is working fine and everything seems be ok, except for my reservior. Every now and then (like in past) it has the need to spit out coolant from the "excess hose" (little rubber hose located on the passenger side's firewall. When it does that, it burns off on something below it then it just stops until the next time it decides to do it again. Why is it doing this? Am I building up pressure somewhere? Is it possible that my ac/heating system has gone bad and causing some problems? Need help. Thanks.
