Re: 1987 Chevy Truck heater hose
We are asking because there are no nuts on normal heater hose set ups. Everything is clamps, and the 'correct' ones I have worked on have no pipes inline, only connections at the water pump / manifold and heater core. With A/C there might be a Ranko vacuum actuated valve in the hose. So a picture of your issue area would be helpful.
