Hello about 3 days ago I purchased a 99 Subi Obw 2.5 l 162k on body and 100k on motor and tranny . I took it for a 5 min test drive and drove great, no rust , like new kid said you "should" have the timing belt and head gaskets done but car runs great . got the title drove it 10 miles started to overheat looked like coolant got onto the belt and frame, of the engine let it cooled down limped home etc. Next day same thing over heat within 2 mins coolants bubbling I accidentally overfilled w coolant. Temp needle jumped way above hot and stuck there after car was shut off . Now I spent all this money on this car he wants another $400 to do timing belt and head gasket and water pump supposedly. you think I caused damage driving it a couple miles like that ? I heard air in the system , thermostat any suggestions on Diy ?
