            Does what it needs to do

            A very easy part to replace . Mine had a leak on the stock one . I bought this one and it was better quality than the stock one.

            Turns out, the desgn on the oringal over flow tank has a flaw. Mounted on the side put a lot of weight on plastic. You can develope a leak. Quick replacement... Go inspect your tank today. Great product, quick fix, fast response by Extreme Terrain

            Serves its purpose

            My Rig: 2015 JKU Sport, Auto The bottle I received is NOT an exact match of the OEM bottle. It's about 95 the same. The OEM bottle secures to the back of the fan shroud in three places - the upper and lower slide tabs that insert into the fan shroud, and the plastic tab that connects to the fan shroud via a plastic push pin. This replacement bottle only connects using the two slide tabs. The bottle i received did not have the additional tab. When i installed it, the bottle fit snuggly, but not tightly, like the OEM one. The bottle was still able to wiggle a good amount side-to-side, whereas the OEM bottle was firmly against the fan shroud due to the additional plastic tab. My recommendation is that if your rig is mostly driven on the road, then this bottle will suffice. If you wheel your rig a good amount, the rocking and jarring of off road may knock this coolant bottle out of its slide tabs, possibly resulting in a coolant leak / spill on the trail.

            Was going to cost $190 at the dealership. Always look somewhere else before letting the dealership fix.

            Fit perfectly

            Just like the OEM. Only difference was OEM had an extra tab that really wasnt needed. 0 issues yet. Recommend if needing a replacement or even a spare.
