"I purchased this item for $57 from these guys and it was a further &41 to send it to New Zealand which is about as far from the states as you can get. The same product from the dealers here was $900. It arrived in 4 days correct part and even had a radaitor cap on it (I just bought one here for $75!)" posted by: cadillacrex on August 14, 2014

"the expansion tank fit and does seem to perform just fine. Its made in china. which seems far away from a quality german manufacturing plant. but one must make a profit... this is the third tank installed in the vehicle. bmw 330xi 2002 model. the first from the factory a second one installed by a bosch certified shop and two by me. the other tank seemed to have a crack around the top seam of the box. the overall design is way too complicated and uses way too much plastic bs. watch out for the bleed screw it breaks. use it once and only a couple turns after the thermostat has opened but note that the head of the junk plastic screw will separate from the screw body..." posted by: another mechanic on November 5, 2013

Select your BMW Coolant Reservoir model from the list below.

OES Genuine Coolant Reservoir

A car's coolant reservoir--part of the engine's cooling system--should always be working and in good condition to prevent engine overheats. For any leaks and damages, a new one from OES Genuine is a good choice for a new unit if a simple replacement is needed. The part does a great job of maintaining the right amount of coolant and water in the system no matter the engine and coolant temperature. The plastic used for the container is also strong and durable enough to hold liquids to prevent leaks. OES Genuine coolant reservoirs are a direct-fit to a car's engine compartment, which allows for easy installation and maintenance.

BEHR Coolant Reservoir

For a German make such as BMW, there's no spare part more authentic than from one from a fellow German company like Behr. The company specializes in all things air conditioning and cooling. Its lineup of coolant reservoirs for European cars can be classified as one of the best. As an OE replacement, each product is carefully designed to match a car's unique size and specification. The reservoirs already include all the connectors and fasteners needed for quick installation. Best cooling results can be achieved when the coolant reservoir is used with other Behr products for the whole cooling system. But as a direct replacement, Behr can definitely deliver all the cooling the engine requires.

APA/URO Parts Coolant Reservoir

APA/URO Parts is a great source for high-quality and OE-replacement parts. It is known as another aftermarket company that produces for European cars like BMW. Tougher aluminum-thermostat housing is used for its coolant reservoirs in place of the weak plastic that has a tendency to produce cracks due to intense heat. It really takes a lot before these tanks begin to fail. Each part is also crafted to exactly stand in place of the stock unit for easy installation. Adjustments and modifications aren't necessary. All prematurely damaged and failed parts can easily be replaced with a 24-month unlimited-mileage warranty. APA/URO Parts coolant reservoirs are perfect for any BMW that needs a replacement.
