Had to do the intake manifold gasket thing at 71k.
Now it's 140k and the radiator's gone.
But when they where checking the radiator, they noted that the intake manifold gasket was leaking.
I guess I made an unwarranted assumption back at 71k: that the failure was due to a inadequate OEM gasket and that the new one would be better.
Bad assumption? Do these things go about every 70k miles?
