Cold operating conditions can make oil thicker, so heater plumbing helps move warmed fluid through the circuit more effectively during startup and temperature recovery. This hose works in a fluid-transfer role, where routing, sealing, and material condition all affect oil movement. Cracks, soft spots, or leaks can disrupt the heater circuit and create service issues around the connected fittings. The Mack 23285701 restores the hose section used in the oil heater system.
