It looked just like the photo, and was easy to install. It is working as advertised at this time.
Customer Q&A
i want to bypass my heater, is this the part i use? or can i just cut the hoses and put a 'u-fitting' on?

This valve is to control the flow of coolant through the heater core. If you are looking to entirely bypass the system this will not be the appropriate part. We recommend visiting an online automotive forum for your vehicle to find complete bypass instructions.
