Technical Specifications: Premium Heavy-Duty Coolant Expansion Tank (17214674 / VOE17214674)Premium Heavy‑Duty Coolant Expansion Tank (17214674 / VOE17214674) — Engine Cooling System Stabilizer
Our Premium Heavy‑Duty Coolant Expansion Tank (Part Number: 17214674 / VOE17214674) is a high‑strength pressure‑stabilizing reservoir for engine cooling systems. Installed in the upper engine compartment, it compensates coolant thermal expansion, removes trapped air from the cooling circuit and maintains stable system pressure. Designed for VOLVO D6 and D7 diesel engines, it prevents coolant boiling, hose collapse and fluid loss under continuous heavy‑load construction‑site operation.
Core Technical Advantages
High‑Density Thermal‑Stabilized Polymer Construction: Heavy‑walled polypropylene composite material resists hot‑coolant scaling, chemical cracking and high‑temperature aging under harsh under‑hood conditions.
Reinforced Filler Neck with Overflow Port: Precision‑threaded neck ensures tight sealing with the pressure cap, safely releasing excess coolant during thermal expansion spikes.
Integrated Coolant Level Indicators: Molded visual markers allow quick coolant‑level inspection without opening the hot pressurized tank.
Vibration‑Resistant Mounting Lugs: Heavy‑duty mounting tabs fit factory brackets perfectly, evenly dispersing engine vibration and avoiding stress‑crack damage.

Professional Tech Note:
Aging expansion tanks suffer from polymer brittleness, micro‑cracking and coolant leakage. Loss of system pressure causes boiling, water‑pump cavitation and engine overheating. Replace the tank together with a new pressure cap and inspect coolant hoses during overhaul. Use properly mixed antifreeze coolant. Verify machine Serial Number (S/N) for correct port and mounting‑point fit prior to bulk ordering.
