2001 Subaru Outback 4dr Wagon

165-horsepower 2.5L H4 5-speed manual AWD

91300 mi US $120 The engine code identified the idle air control valve as the problem. My mechanic cleaned the idle air control valve rather than replacing it. This problem crops up every 3 years in the winter time.  
100500   Difficult to read the mechanics notes, but it looks like "replaced Anful Ratro Sensor." 
108000   When the car refused to start, it had to be towed to the mechanic, who diagnosed a bad fuel pump. He replaced the fuel pump with sending unit. Labor was only $110, but the parts were $414 before tax. 
111000   Car failed to start, on more than one occasion. Finally drove it to my mechanic, who replaced a bad crank position sensor. 
119000 US $160 Knock sensor was not working correctly; car frequently lit CEL. Code "P0325" came up. 
124000   Radiator was leaking. Noticed it one day while parking car after a snowstorm. Green dots covered the driveway. Mechanic found radiator leaked during high-pressure testing. Dropped car off 8 AM, had loaner for the day. 
136300   Belt slipping. Was tightened right then and there with no appointment needed. Junction Auto (New Haven, VT) is an excellent repair shop. 
169000   Replaced oil pan for rust spots.
