Fits like OEM piece
Dropped right in fits like a champ. Very happy that Amazon had these available.

Rubber hose not long enough
Fits good. Rubber hose to radiator cap is not long enough for a 2014 dodge avenger. Keep the old hose

Installs easily and works perfectly.
Good quality, Exact OEM replacement. It took me 10 minutes to install and the mounting holes lined up perfectly. The coolant level sensor works well, told me when my coolant was low and turned off when I filled it up. My OEM reservoir coolant level sensor went out. This one was exactly what I expected and is very good quality for the price.
