About this item

  • What Does a Coolant Reservoir Do? - A coolant reservoir is a small plastic tank that is connected to the radiator of a car’s cooling system. Its primary function is to provide a space for excess coolant to expand and contract as the engine heats up and cools down. Keep the engine operating at a normal temperature.

As an automotive design engineer, I initially believed the build quality of the coolant tank to be at least that's good as the current OEM offerings. Unfortunately the seam between the top and body spilt... after being in use for only 2 weeks. Unfortunately this happened hundreds of miles from home while on a road trip. Ended up spending a lot more to have the vehicle towed to a nearby dealer and buying an OEM replacement.

The part was well packed with a plastic cover protecting the coolant sensor and padding around it.The part itself looks well made and seems of decent quality. I did notice that the Max/Min indicator inside the product is noticeably lower than the original part but that could be because of it being a more updated part design.This fixed my coolant leak issue on my 2012 X5 3.5i. 4 stars because you just are never quite sure how long a part like this will last…but the price was right!
