tosca1 Posted August 24, 2014 Share Posted August 24, 2014 My 2003 outback has a faulty headgasket but still drives. I am not losing coolant nor is the coolant/water mixing with the oil. There is very little drip on my garage floor of oil but very, vey little over a long period of time. Sometimes I can get away with taking it a few miles and other times it registers through the roof that it is overheating. The fans work perfectly, there is a new radiator, the cap has been replaced, there is no white smoke out of my tailpipe, no residue in my oil, and yet there is this overheating. Can you give me any idea what it could be ?Thank you. Quote Link to comment Share on other sites More sharing options...
Svxpac Posted August 24, 2014 Share Posted August 24, 2014 I have had this problem with my SVX. I replaced the head gaskets, the water pump, the radiator, cap, and one of the fans that wore out. It still overheats. My dealer says I have a cracked block. They used some device that measures pressure in the radiator as well as whether or not it is intake or exhaust which is leaking. Ask them about this. Good Luck! Svxpac Quote Link to comment Share on other sites More sharing options...
tosca1 Posted August 24, 2014 Author Share Posted August 24, 2014 thank you. It has been examined by 3 mechanics and they never suggested that one but I'll check into it. Thanks again Quote Link to comment Share on other sites More sharing options...
farmer Posted August 24, 2014 Share Posted August 24, 2014 Why do you say it's a headgasket issue? Is that because it's a common problem with overheating? I would pull the thermostat and see if that stops it. That would give you another path to either fix or crutch it along. Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted August 24, 2014 Share Posted August 24, 2014 I see no mention of thermostat, aftermarket thermostats in subarus is a big no no. If you do not know or have an aftermarket in the car you need to get it swapped out for an oem before the overheating does serious damage to the engine.

propane Posted August 25, 2014 Share Posted August 25, 2014 How many miles on car? auto transmission? When it overheats, have you (or been asked by mechanics) seen if thecoolant has been overflowing into plastic reservoir? And subsequently thermo siphoningback into radiator (when eng is shut off.?) this is a function of radiator cap working properly Coolant ( same type) should be kept at least to min levelon side of overflow (yellow cap). What basis is the assumption of HGleaking(asked earlier) Quote Link to comment Share on other sites More sharing options...
