Perfect Replacement – Great Price
Five stars. My old coolant tank was yellowed, weathered, and leaking at the seam. I do Amazon Flex deliveries on a lot of rough, unpaved roads, so it finally gave out. I replaced it with this one and it fit perfectly. It’s the same tank they sell at AutoZone but for about half the price. Installed easily and works great. No more leaks. Very happy with it.

Perfect replacement part for my 2013 Chevrolet Cruze 1.8L and has upgraded metal insert fittings
Perfect replacement part for my 2013 Chevrolet Cruze 1.8L. I was having an overheating problem on a car I bought where the previous owner said the engine needed replaced because of a cracked head. Turns out, it was simply the radiator cap not holding pressure, allowing the coolant to boil over. This container and cap combo was only $3 more than the cap itself. It has upgraded metal inserts in the hose fittings making it stronger than the OE part. The fit was perfect. Very happy with the purchase. Fixed my engine completely!

Better than stock
Reinforcing inside the nipple ends for hoses and a new cap well worth the money

Worked good while it lasted
Product is great, worked good for my 2012 Chevy Cruze. My car did blow up recently though with an issue due to the coolant all escaping but it wasn't from the reservoir. So would recommend. Also was easy to install and fit how it should've.

Better than OEM
A much better design than the OEM. This one has steel inserts formed into the hose attachments.

Perfect
This was for my 2014 Chevy Cruze…. a very needy car lol. It was so close to the original that I couldn’t tell any differences. Fits like a glove. I don’t use this car anymore but I used this for about 6 months after changing the reservoir. The only leaks I came across was not putting the hoses back tight enough (operator error😂).

This is exactly as it should be and better than oem. It has Steel sleeves on the rubber hose outlets so they won’t collapse with clamp pressure

This is an excellent product and comes with the re-inforced inlet/outlet pipes that probably won't break off like the originals. Fit perfectly into position on a 2013 Cruze. Very happy with this purchase and was particularly pleased to find a "brand name" product for a great price rather than an anonymous product with unknown heritage. Recommended.
