I replaced it with this unit, and I’m very satisfied with the results. The reservoir looks just like the factory original. I’m not certain if it’s OEM, but the fit and finish are excellent. Everything lined up perfectly, and the installation was quick and straightforward—I had it installed in less than 15 minutes. After filling it with coolant, everything is working exactly as it should with no issues. Shipping was fast, and the product arrived in great condition. I appreciate the quality and ease of installation. Great price and I would definitely recommend this product to others.
