Hey all. I joined this forum for my little sister. She owns 2007 Mazda 3, 5spd, 2.0 4Banger. She has wrecked it thrice times and I have repaired it every time. The last wreck tore off the front bumper and cracked the radiator.

Replaced the whole bumper and a new radiator, hoses, and hose clamps. She drives like a bat outta hell and one day she noticed the car was overheated. So I went through the whole car looking for a coolant leak; checked the radiator, checked the hoses, checked the water pump. Nothing at all. I think she might have warped the heads. The fan still works, it still comes on when the car is at an idle.

That being said; where can I find the replacement parts? And do they make a nicer/thicker gasket for the heads? I want to go aftermarket on the gasket and would like to stay stock on the heads.
