Ok today letting my turbo cool down i noticed my car running hot. I popped the hood and the antifreeze container thing was almost full i let the car cool down and the antifreeze was low in the radiator (no leaks nothing). When we did my rebuild my stupid mechanic didnt get a new thermostat but he got a new water pump so i know its not the water pump. So do you think the thermostat is my problem or is it something else. it has been fine for aobut 2 months until now. thanks
