Ka24de Coolant leak

[Scratchoz]

Anyone know what exactly this hose is for? And if anyone has successfully changed it without removing the intake manifold...

just looks to be a coolant return hose either to your heater core or just the back of the block somewhere, they are all a pain in the butt no matter what! 90 degree needle nose or a 45 degree will be ur best friend
