Product Number: 19041006
The Highway Automotive 19041006 (RET129) is a coolant expansion tank designed as a direct replacement for RVI and Volvo commercial vehicle cooling systems. Built to restore proper coolant reservoir function, this unit supports the pressurised cooling circuit with a cap rated at 90 kPa, ensuring the system maintains the correct operating pressure under working conditions. Constructed to meet the demands of heavy-duty truck applications, the RET129 expansion tank provides a secure, sealed reservoir for coolant overflow and return. The 90 kPa cap specification is a key fitment detail — ensure any replacement cap used with this tank matches this rating to maintain system integrity. This expansion tank covers 16 vehicle applications across the RVI Midlum range and Volvo FL series. RVI Midlum fitment spans a broad spread of engine variants including MIDR 04.02.26, MIDR 06.02.26, dCi 4, dCi 6, DXi5, and DXi 7 units, covering models from the Midlum 135 through to the Midlum 280. Volvo FL and FL II variants fitted with D6B and D7E/F engines are also covered. Full application data is available via the vehicle selection tool. The unit is supplied as a single expansion tank. Gross weight is 3.7 kg and package dimensions are 630 × 410 × 180 mm. Manufactured by Highway Automotive and supplied through PartsForMachines with our Fit Guarantee — if the fitment shown does not match your vehicle, hassle-free returns have you covered.
