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

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!

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.
