  1. So... My brother has a 98 Legacy, I believe its an EJ25. Bare with me, there is a lot of random symptoms/info here. Occasionally it overheats, so I looked at it. Its spitting out trouble codes P0480 and P0483, which are both fan related. Fans seem to work fine, while watching them. With my scanner, I watched the temp rise (the defrost was on), the fans (and ac compressor) would come on for about 30 sec then turn off. And the temp continued to rise. At 215F I turned off the defrost and the temp returned to 185F. What? Thermostat opened? Extra load eliminated? Weird thing is, when its running hot the coolant doesn't 'seem' to be flowing... Top radiator hose hot, low cold. I can open the radiator cap even when hot, which seems no pressure. I can put my finger in the coolant and its merely cool or lukewarm. Haven't drained to check thermostat, but he says it was replaced 'last time.' Radiator cep he hasn't replaced. So... (In order of my personal unprofessional opinion and economical preference)... Rad cap? Clogged radiator? Failed pump? Thermostat? Head gaskets... I have but didnt use a compression/head tester due to the apparent lack of coolant flow. But theres no bubbles in the coolant reservoir. I dont thinknot will tell me anything. All input appreciated. Thanks all.
