The upper/lower radiator hoses and all heater hoses should be checked for deterioration, leaks and loose hose clamps every 15,000 miles/12 months (1973-79) or 30,000 miles/24 months (1980-83).
REMOVAL & INSTALLATION
See Figure 1
- Drain the cooling system.
- Loosen the hose clamps at each end of the hose.
- Working the hose back and forth, slide it off it's connection, then, install a new hose, if necessary.
When replacing the heater hoses, maintain a 11/2inch clearance from any surface.
- To install, reverse the removal procedures. Refill the cooling system.
Draw the hoses tight to prevent sagging or rubbing against other components; route the hoses through the clamps as installed originally. Always make sure that the hose clamps are beyond the component bead and placed in the center of the clamping surface before tightening them.
