Mishimoto Aluminum Coolant Expansion Tank, Black - Fits Select 1992-2002 BMW 3 Series and Z3 (MMRT-E36-92EBK)

Fits select 1992-2002 BMW 3 Series (E36) and Z3 (E36/7, E36/8) models including 323i, 325i, 328i, M3, and Z3 M.

The Mishimoto Black Aluminum Coolant Expansion Tank addresses a critical failure point in the BMW E36 and Z3 cooling systems. Factory plastic expansion tanks are prone to cracking and catastrophic failure after years of constant heat cycles. This tank is engineered from durable, TIG-welded aluminum for optimal longevity and pressure resistance under high-performance driving conditions.

This unit features a CNC-machined aluminum dipstick that doubles as a bleeder valve, allowing for accurate cold coolant level monitoring and efficient system bleeding. It is designed as a direct fit for the factory mounting points and is fully compatible with both stock fan shrouds and the Mishimoto Performance Fan Shroud Kit.

• Construction: Fully TIG-welded aluminum for maximum durability during extreme temperature transitions.
• Integrated Maintenance: Included CNC-machined dipstick for level checks and system bleeding.
• Finish: Stealthy black powder-coated finish for improved engine bay aesthetics.
• Installation: Direct-fit design installs in under one hour using factory hardware.
• MPN: MMRT-E36-92EBK
• Warranty: Includes the Mishimoto Lifetime Warranty.
