Molded Coolant Hose; 20.75-Inch Long; 1.50-Inch and 1.75-Inch ID (Universal; Some Adaptation May Be Required)

Efficient Cooling Upgrade. The Coolant Hose delivers dependable fluid transfer for stable operating temperatures, pairing proven materials with precise dimensions for leak-resistant performance. It measures 20.75 inches in overall length and features molded construction for consistent routing. This model is a universal fit, making it a practical choice for a wide range of cooling system layouts while serving as a direct replacement for Part Number 70863.

Construction and Appearance. Built from robust molded material, the hose resists collapse under suction and maintains shape under heat and pressure. Its matte black finish provides an OE-style appearance that blends cleanly into the engine bay while also helping to hide grime between service intervals. Compliance with SAE J1684 Type EC and SAE J20R4 Class D-1 standards underscores its resistance to coolant additives, heat cycling, and abrasion, promoting long service life. Dual-size ends—1.50-inch internal diameter on one end and 1.75-inch on the other—accommodate differing neck sizes without adapters in many layouts.

Installation. This hose is engineered for versatile installation, using molded bends to route neatly around adjacent components and minimize kinks. The direct replacement design for Part Number 70863 supports a straightforward swap: drain as needed, transfer clamps, seat the hose onto clean necks, and tighten to specification. The sturdy wall and bead-friendly ends help clamps bite evenly for a secure seal, reducing the likelihood of weeping at the connections after heat cycling.

Application. This Coolant Hose provides a universal fit. Beyond serving as a simple replacement solution, it enhances serviceability by matching common neck sizes and maintaining stable flow through its molded path, which can improve warm-up consistency and reduce hot-spot potential in the cooling circuit.
