Introduction

The valve is under the hood, right next to the firewall, and is responsible for managing the heat flow of coolant to the heating system. This can be a difficult area to maneuver in, so be careful with your hands when replacing the part.

It is very important to make sure your engine is completely cool before replacing your valve as you will be working right next to all of the hottest parts of your vehicle. Additionally, if your vehicle is not cool, some coolant might be lingering inside the heating system, which could result in coolant spilling on you, the ground, and your vehicle.

With that said, this is a relatively simple repair; all you need is the replacement valve, some pliers, and a pair of gloves.

What you need
