hey guys as some of you may know i bought a mx83 cressida for my partner to get around in. i hadnt really taken much notice but it seems to be using a bit more water than usual, and the reservoir fills up to the top.......and doesnt go back into the radiator when it cools. I'm pretty sure it isnt a blown head gasket, which was my first thought, since the car still runs and drives as well as the day i bought it. are there any other reasons why this could be happening? its a 7m-ge too. any help would be great. cheers brendan
