Asked by Klogan53 Aug 12, 2015 at 07:33 PM about the 2003 Subaru Outback Base Wagon

Question type: Maintenance & Repair

Just had my mechanic fix the squealing belt for my air conditioner. Now a couple days later my car is overheating and check engine lite is on. Also noticed that the blue cap that goes on a pipe just above the oil filling compartment was missing. I believe that pipe runs to the air filter. Could that have done it? I found the cap (was next to the battery) and screwed it back on. See photo attached blue cap above oil reservoir.  The belts look ok but scared to start car.... Any ideas? I am scared! Just bought this car in April! Any ideas or help will be greatly appreciated! Karen

The blue cap looks like where you put your freon in your AC.
