I know did some searching but couldn't find the any detail on this issue. I recall on my precious car, when I purchased an AEM intake, I had to re-route the coolant using a different hose that came with the kit. To do this I had to drain the engine coolant so I could remove the hose and install the new hose.

Now, for the TSX. I found this guide for installing the CAI.

I found this Intake Install guide and noticed in the photo some coolant leaked onto the engine.. Do I need to drain the Engine coolant and replace the coolant hose with one that's provided with the Injen Intake? Just want to prepare myself for any additional work.

Thanks

 

The coolant spills out like no more than a small cup, so a rag or cloth that you won't use anymore to help make the spill less.

Its just rerouting that hose.
