BMW 3.0CS Coolant Reservoir

The Coolant Reservoir in the BMW 3.0CS is designed so that heated antifreeze is collected and returned when the engine cools. This has given the classic coupe a reputation for rock solid reliability. The Coolant Reservoir is located above the radiator to avoid air pockets that can corrode metal components, so drives are worry-free in a BMW. The early iterations of 3.0CS model cars come with a simple plastic lid non-pressurized overflow style Coolant Reservoir. The later 3.0CS model cars are equipped with the reinforced pressurized Coolant Reservoir that carries the metal pressure cap. The metal pressure cap also lets unwanted air escape freely from the radiator and Coolant Reservoir without spilling any of the precious coolant. Each style features molded level markers to notify owners at a glance whether the system holds the correct volume of any liquid. This small feature adds extra safety value day to day. Thanks to the automatic calibration of the Coolant Reservoir to account for fluid expansion and contraction, the straight six stays at its ideal operating point. This allows the first engine component to function at maximum power output while minimizing fuel consumption. An interchangeable Coolant Reservoir that covers all production years of 3.0CS means you will not have to hunt for parts for carbureted early examples due to an update in later models. This is especially useful for BMW enthusiasts that wish to preserve the original character of their vehicles. The sturdy plastic employed in this component does not crack after many decades. The robust feel here is reminiscent of old BMWs. This factory original Coolant Reservoir is produced to meet BMW cooling specifications to retain the authentic rhythm of the straight six in every 3.0CS. When paired with the agile chassis of the coupe, a hearty Coolant Reservoir ensures cooling consistency during spirited runs or relaxed highway cruising, reinforcing the grand tourer spirit for the 3.0CS and thus the BMW coupe experience.
