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

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.

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.
