Have a 1993 4runner 3v auto with 150k miles. Recently replaced all solenoids and thermostat and shes been running beautifully until I noticed the coolant leaking. Not significant, but something I want to address asap. Found the source but cant put a name to this hose. Can anyone help me out? pics added. Leak is coming from a hose on front drivers side. Not coming from the thermostat.

 

Pics are a bit ambiguous.
Hose from water pump to oil cooler??

 

Yep, I think you’re exactly right. It’s the hose right next to my thermostat. Hose hasn’t completely gone out yet. Anyone have suggestions for a fix? More pics.

 

Buy a replacement hose.
Drain and capture the coolant at the radiator drain and change it out.
