"The female electrical connector on the replacement reservoir had a nib (raised portion) inside its plug that prevented the male connector on the vehicle wiring harness from being properly seated. The offending nib had to be removed (cut out) in order to make a good connection." posted by: Chats on December 6, 2010

"The part body fit well, the sensor connection was difficult to connect because of burrs on the casting." posted by: boss on October 13, 2009 view all 3 reviews

"The item was easy as 1-2-3 to install. It was an exact replacement for my damaged reservoir. The cost was $50.00 less that anything that I could find locally. I guess I must have missed the possibility of express shipping but the last item I purchased from this company arrived in 2 days. I will look for that option next time when I need it faster." posted by: J.D. on December 9, 2013

"Called my mechanic when the old bottle began to leak and he said the only place to purchase this in town was at the car dealership. Saved plenty by ordering online. It the old hose is difficult to remove, keep pouring boiling hot water over it to soften and remove. So glad I found this website. This is a very easy do-it-yourself job." posted by: Cece on February 12, 2009

The Dorman expansion tank is an excellent choice when it comes to replacing the worn out one on your vehicle. An expansion tank is important if you want to save up on the coolant. As the engine heats up, the coolant expands, causing it to overflow and out it goes into the pavements. But that is not so with an expansion tank as the coolant will overflow into the expansion tank. Since a cooling system equipped with an expansion tank is practically a closed system, the coolant can flow between the system and the expansion tank as it expands and contracts. In this way, there will be no coolant lost if the system is functioning correctly. Another function of the expansion tank is to get rid of the air bubbles from the cooling system. A coolant without air-bubbles will be much more efficient than coolant with air bubbles, as it absorbs heat a lot faster. The advantage of the expansion tank is that while the level of coolant contained in it increases and decreases, the radiator will always be full. The earlier cars can easily be integrated with expansion tanks, simply by mounting the tank near the radiator, connecting it to the overflow tube, and replacing the radiator cap. If your expansion tank is already inefficient, replace it with a new one. That way, it will be more practical on your side plus the chances of you damaging the environment will be decreased. The Dorman expansion tanks are guaranteed to be functioning efficiently and they are guaranteed to have a long service life.
