Dorman 603-383 Pressurized Coolant Reservoir with Cap Compatible with Select Buick / Chevrolet Models

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 and saved me 460 dollars from dealership

Coolant tank appears to be a quality build and fit perfectly.

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!

Arrived quickly and is an upgrade compared to the original one that came in my 2014 Cruze

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.

Fits well. Upgraded hose clamp area. Time will tell how it holds up but looks well built.

Fit my 2012 chevy cruze LT 1.4 l turbo RS and was easy to install. This is necessary to change out people. Especially if the original or current one is yellow in color then it has gone thru oxidation process and can have hairline cracks that you don't see. I went ahead a changed out a few of the spongie feeling hoses too. But since I decided to do that only bc one of the hoses had deteriorated and had to be changed right then and there so I had to pay more and buy the hoses at Advance Auto Parts and pay like probably 3x the pric3 bc of the mark up of a middle man like Advance, AutoZone, O'Reilly and just think the markup a mechanic small mechanic shop w/ overhead charges his customer for this same part we can order ourselves

The Dorman part is what I should have bought a long time ago.......this part installed in a few minutes. I have purchased others, only to have them fail in a short time. Thank you Dorman for making a quality part

Very good quality .. better than the original one and seems durable

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.

Excelente relación Precio/Calidad, antes de seguir diré que se instaló en un Cruze 2015, primero fui a las tiendas locales de autopartes y los reemplazos los vi de calidad inferior así que confiando de la fama de la marca DORMAN lo compre, este tiene refuerzo de metal en las dos conexiones la superior y la inferior (el original solo trae refuerzo en la superior) es casi idéntico al original y se siente y se ve de buena calidad, tenía mis dudas porque había leído reseñas donde comentaban que venía muy pequeño la conexión superior y simplemente no alcanzaba a sellar, me pasó!!!! Fugaba por ahí pero no es problema del depósito, ya que lo medí con bernier y miden casi lo mismo, el problema en si es la manguera que ya tiene moldeada la abrazadera, simplemente cortas aprox 1cm de manguera donde esta la marca de la abrazadera y listo cero fugas. También leí comentarios donde decía que el tapon dejaba escapar la presión, yo no tuve ningún problema de este tipo, como dije es un buen reemplazo del original a un excelente precio, solo toca ver cuanto dura.
