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

Perfect replacement tank and superior quality!
This Dorman replacement coolant tank was absolutely a perfect replacement for my 2013 Chevy Cruz. Perfect placement and the quality of the build is twice that of the original OEM tank. The amazing part is the replacement tank had what appears to be stainless steel tubing reinforcing the inlet/outlet tubes. The OEM tank didn't have that. Thank you Dorman for rescuing me from 3 months of total terror from cooling issues with my vehicle. Recommended 100%.

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.

Quality at bargain price!
Perfect fit. Looks & feels durable. It cost me only 20% of what the mechanics want for the part, plus they want $200 for labor. I watched the tutorial on Youtube, and it took me less than 30 minutes to remove and replace the original equipment. A great buy!

Best Uprgrade over OEM
Are you tired of the OEM reservoir leaking and giving off that smell of antifreeze leak that you can never find? This is the solution that will fix that pesky leak that you seem to never find! This is the only one that has metal inserts in the outlets the helps to prevent leaks from happening. If you own a Chevy Cruze then you know exactly what I'm talking about. Your antifreeze in the reservoir tends to go down a half an inch over a month but can't find any leaks but you can definitely smell a leak; then it's time to change out your OEM reservoir with this one and you will no longer have a leak or smell of antifreeze. Problem solved!

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.
