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?
