This heavy‑wearing silicone hose with OEM numbers 1676216 and 1660277 is tailored exclusively for Volvo heavy‑duty trucks. It shifts engine coolant steadily to preserve reliable cooling performance throughout service life.
Constructed from rugged heat‑withstanding silicone, it stands up to high pressure, frequent vibration and natural wear‑and‑tear consistently. As it blocks coolant seepage effectively, it elevates cooling system stability and ensures smooth long‑haul heavy‑load travel.
