If the person that replaced them last time missed one step, and that is a little RTV on the bolts, they will weep coolant to the top of the LIM. To fix this you need to remove the bolts, and that means pulling the supercharger to get to them, may as well go one more step and replace the LIM gaskets. 2 years seems to be where the bolts start to weep. I've seen the plastic gaskets start to fail in a year, but can still last 100k miles. Generally, when the gaskets fail they don't leak to the outside of the engine.
