anybody know the cooling system flow on the 2.5? is there anywhere coolant could get into the intake(such as on v6 or v8 engines where coolant passes through the intake manifold, and it the gasket corrodes/leaks, coolant can leak into the intake passage before the cylinders)??

 

Follow the drivers side heater core line and there should be a Tee coming off of it toward the intake manifold and it connects to a nipple underneath and passes through to the drivers side.
