Always read the sellers description and where it's coming from. Amazon indicated this would not fit my vehicle, the seller listed my vehicle as a direct fit replacement. It fit just fine. It wasn't the cheapest but at least it was in the US. Most of the part are made in China but I will not purchase anything coming directly from China! Don't send your money directly to China! Don't be a sellout support our US businesses!

Awesome item, well built and very quick to install. However the reservoir continued leaking because the O-ring in the radiator cap was shot. Bought a new cap and I don't have to worry about leaks again. Now I have an extra reservoir just in case.

Great device I purchased for my Mercedes-Benz GL450 great price and very reliable

After replacing the reservoir because the original had a cracked vent line the gl450 began overheating and boiling the coolant out. This prompted replacing the thermostat and then the water pump with still the same problem. After rigging up a pressure tester to the vent line instead of the cap I discovered thereservoir held zero pressure even using multiple caps. A new tank immediately solved this and the system builds 15psi. And I missed the return window by just days. Although what this cost me was much more than the price of a reservoir..

The part fit perfectly but when I received it the bracket was broken off but I have repaired it to work. Thank you

Excellent Quality, recommended. Come with new fluid level sensor built in. Matched perfectly! Love it when a part comes and goes in and does exactly what it is supposed to do with a cost savings!!!

Very Easy Install! Fits exactly like the original factory part. Saved a lot of expense replacing part this on my own. Great Value!

The media could not be loaded. The item arrived it appears to be fine intact brand new condition I installed it in my vehicle filled it up drive around it function the reservoir had no issues from what I can tell however my car started overheating due to a leak several months later I realized you need to water level indicator does not work so this item is completely useless there's no way to replace the water level indicator you have to replace the whole Reservoir so this items been defected from from the day I bought it
