I don't know, I kept hearing about HG problems in legacies as well and mine never had an issue after 14 years and 161K miles. Of course, I drove that car from day 1 and know it was never abused. I don't know about this car.

Go borrow a block tester kit from Autozone or other local auto parts shop. Its simply a vial you fill with special blue fluid, and set over your radiator filler neck. It detects exhaust gases and will turn yellow if they are present in your cooling system. Cheap, easy, and can save you a lot of hassle replacing little stuff here and there that arent necessary.
