Perfect fit for my 2020 Chevrolet 2500 HD Custom Crew Cab
I have a 2020 Chevrolet 2500 HD Custom Crew Cab, and my coolant reservoir developed a burn spot near the top that caused coolant to leak out. I replaced it with this unit, and Iโm very satisfied with the results. The reservoir looks just like the factory original. Iโm not certain if itโs OEM, but the fit and finish are excellent. Everything lined up perfectly, and the installation was quick and straightforwardโI 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.

Canโt beat this price and saved me 1,000$ dealer bill
Item was easy to replace. Saved me a trip to the dealer because my old one cracked and was leaking daily. This item was 100% brand new and oem fit. No leakage and no problems. Thank you.

Very good!
Installed on a 2005 Chrysler 300C 5.7 Hemi RWD and it installed perfectly no issues. Look up their video on youtube and it's so damn easy. If your coolant reservoir is faded/dirty replace it!! My old one had dirt and other crap in it. It's super clean and makes the engine bay look good.
