Product Number: 15031003
The Highway Automotive 15031003 is a replacement coolant expansion tank designed to fit MAN heavy commercial vehicles across the TGA, TGS I, and TGX I model ranges. With 13 confirmed fitment applications covering multiple engine variants including the D20, D26, and D28, this part provides a direct replacement solution for operators maintaining MAN truck fleets. The expansion tank accommodates the thermal expansion and contraction of coolant within the closed cooling system, maintaining correct system pressure and fluid levels during operation. As a standalone replacement unit, the 15031003 is supplied as a single assembly and is manufactured to serve the demanding duty cycles typical of MAN TGA, TGS I, and TGX I platforms across all engine fitments. Sourced through the Highway Automotive range, this part is suited to workshop and fleet operators who require a reliable, specification-matched replacement component. The part ships as a packaged assembly measuring 1075 x 560 x 310 mm with a gross weight of 8.4 kg, reflecting the substantial construction of a heavy-vehicle coolant expansion tank. These dimensions should be accounted for when planning storage or handling on arrival. Fitment is confirmed across MAN TGA (all engines including D20, D26, D28), MAN TGS I (all engines including D20 and D26), and MAN TGX I (all engines including D20 and D26) — 13 applications in total. Buyers are encouraged to verify engine variant using the selection widget or by consulting the cross-referenced catalogue to confirm precise fit before ordering.
