How old is the hose? It might be time to replace it & if it is then
tightening is just putting off the inevitable.

Subject: Sealant necessary for coolant hoses?

I may be finding coolant leak from where the coolant hose is attached to the
thermostat housing  on my 85.  It should be an easy fix by tightening the
clamp. But I am afraid that if I really clamp it down it may cause coolant
hose damage over time. I probably should take it apart and clean the metal
pipe first then re-attach the hose. My question is should I put some sealant
to aid in sealing the joint to keep it from leaking? What sealant should I
use? What comes to mind is if I use a correct sealant then I won't need to
tighten the hose clamp crazy tight to keep it from leaking. Am I right that
coolant hose can be damaged from over tightening the clamp?
