1-5/16 in I.D. Blue Straight Silicone Coolant Hose | 36 inches

Heavy-duty 1-5/16 in I.D. (1.3125 in) blue silicone straight coolant hose, 36 inches long, intended as a cut-to-length replacement for stock rubber coolant hose on Class 8 trucks, buses, and off-highway equipment. Built from 5-ply silicone with polyester fabric reinforcement for sustained service in the harsh thermal cycling and underhood vibration environment around turbocharged diesel engines.

Signs You Need a New Coolant Hose

• Visible cracks, splits, or surface cuts along the hose body
• Soft, spongy, or swollen sections that collapse under hand pressure
• Coolant weeping at the hose surface or a wet film of antifreeze on the outside
• Crusty white or green residue at clamp connections indicating slow seepage
• Bulging at the clamp ends or a hose that has hardened and lost flexibility

Specifications

Applications

Use as a straight section of coolant hose on heavy-duty trucks, buses, RVs, and industrial equipment where stock rubber hose has cracked or hardened. The 1-5/16 in I.D. size is commonly used for upper and lower radiator lines, surge tank crossovers, and aftercooler / heater plumbing on medium- and heavy-duty diesel platforms. Cut to length with a sharp blade and clamp with constant-tension or T-bolt clamps.

Verify hose I.D., length, and routing before installing to confirm fitment.
