just bought this last week end, 200 000km. Drove fine from vancouver. next day motor got hot, without abusing it. needles just went high. let it coold down added water, next day drove for 300km, slowed down, same thing engine started to get hot... added water it,s ok again. cant smell prestone burning in the exhaust, can see it leaking. expansion vase gets filled up, i would be tempted to think it's only because it's overheating.
i monitored the temp with a android torque app never saw the temps going up, im tempted to think it could be the thermostat that just lets the coolant get out of the expansion vase too early since the expansion vase fills up and i dont need to add much. maybe thermostat sticks closed sometimes?
what do you guys think?
car seems to be lagging a little between 4250 to 5000rpm, im guessing that its turbo related dont exactly know where to start on that one. anyone have an idea on how to troubleshoot?
thanks for your help, im new to wrx!
