# Switching between Hydrocor Light and Hydrocor

IMS PLSS includes a corrosion prediction tool called Hydrocor. The [Internal Corrosion module](https://ims-handbook.cenosco.com/v414/docs/pl-internal-corrosion-assessment) shows a section called HydrocorLIGHt or Hydrocor based on the user's Hydrocor version.

To switch to Hydrocor Light:
