Product Details

Rein designs this expansion tank to match the fit, form, and function expected in OE cooling system service. The virgin plastic construction helps resist cracking from repeated heat cycles, which is important in a pressurized coolant reservoir exposed to constant temperature changes. For Volvo S60, V70, XC70, S80, and XC90 models, EPT0264 provides a direct replacement option for a worn, brittle, or leaking tank.

This part cross-references Volvo 30741973 for the same application.

Common Problems This Part Can Address

• Coolant leaks from a cracked reservoir
• Low coolant level warnings caused by tank failure
• Visible plastic discoloration or heat damage
• Pressure loss in the cooling system
• Replacement of a damaged OE expansion tank

Installation Notes and Tips

Verify vehicle fitment by year, model, and notes before installation. This reservoir is listed for w/o Cap applications, so reuse or source the correct cap separately if needed. Inspect hoses, clamps, and surrounding cooling system components during replacement, and confirm the mounting points are clean and free of damage before installing the new tank.

Quality Assurance

Rein manufactures OE-quality cooling components using materials selected to meet or exceed original equipment standards. EPT0264 is produced from virgin plastic to improve durability in heat-cycle conditions and support long service life in Volvo cooling system repairs.
