Thread: How to tell if you have the GOOD Lower Intake Manifold gaskets.

When people say they "flushed" out their coolant system to put green stuff in I always hope they did it correctly....

The system should be drained and replaced with distilled water and a flushing agent.....then the heater should be turned on, run the car like that, repeat flush. Then flush with distilled water at least 2 more times. Also a good idea to change any rubber hoses
