One note...
these plastic intakes do not just crack at the alternator bracket bolt points. They crack anywhere along that front water crossover. We just had one that split on the bottom. Poured water but you could not see the crack until we got the intake off. The water is hot enough, and if you are not careful about changing antifreeze as recommended, it gets acidic enough that it will eat away the inside of that crossover passage and cause a leak. My son's blew out one night the same way and he had to have it towed home, it leaked so badly you could not fill the radiator completely full, and driving it was impossible as it lost water too quickly...
It is worthwhile to replace it, and a good replacement can be had for $200 at Westwood (dorman)
