My Subaru tribeca B9 had exact same issues couple years ago..I checked everything, flush the coolant system, check for petrol in coolant, read the temperature sensor value...no success but I finally found the solution..when I drive it, I pretend that everything is ok and I'm not overheating, I look straight and never at the gauges... pretty hard to do at first but 40000km done like that and it run like a charm..
These have already been replaced and the issue persisted. I have since found out that it's very likely head gasket or cracked head as the coolant bubbles
Shame it didn't work out but the hose was clearly faulty too. The first thing I would have them check is if the engine is actually overheating, maybe it's just a faulty temperature sensor? They should be able to measure the real temperature of the engine/coolant. Also of course read the diagnostic memory of the car for clues. And they should be able to check the coolant and or oil for cross contamination, before taking anything apart. Or do a pressure test.
The Subaru specialist replaced several parts that were actually faulty in 2022, but the overheating started again summer last year and they checked all components once again and they were fine. Temp sensor, fan, radiator thermostat... all good. The diagnostics didn't show any issues either and also measured the engine temperature and found it wasn't over heating, but fan kicks in when the gauge goes high. No contamination of oil or coolant was found either and pressure is also good. They said that these Legacy engines, although durable, their weak point are the two heads which can crack and cause a similar issue. This was also corroborated by another specialist. They said the only solution was to take the engine apart, but in the Tribeca it's harder and therefore costs more. We are likely to get air scrapped as we spent way over £1k in service and maintenance a year alone and we can't justify the cost anymore.
@ until 2015 it was used as a shuttle between the train station and the hotel and since then we got a long wheel base 9 seat Ford Touneo to do the station runs and the Subaru became a pool car. The tourneo is still with us but doesn't have the same use since Covid, so we potentially could get rid of both and get a SUV.

sound like a good plan!
I had the same issue a few years ago and i replaced the radiator/ temperature sensor and problem solved.

Dude, did you check the thermostat?
like i said in the video, it has been replaced

@GentilsGarage I see. Where is the car used for? Shuttle guests? I'm sure a modern diesel van will be a lot more economical to run 😀
