We get questions all the time from people driving the 24 Valve 5.9 Cummins about how to install a water temperature gauge, and we’re always glad to help out.

In fact, we just found an easier, faster and better way to get it done without having to make any major changes to your Dodge Ram. We know as well as you do that getting the gauge install wrapped up as quickly and efficiently as possible is always the goal.

The main focus for us was figuring out a way to add the water temperature sensor with the least amount of resistance. Not that it’s a really tough process to begin with, but we wanted to streamline it as much as possible.

A water temp sensor adapter was the answer, and that’s where the idea came from for our 1998.5-2007 Dodge Ram Water Temperature Sensor Adapter. With all the conversations we have about 5.9L Cummins water temp gauges, it made sense that we stock the adapter for customers when they need one.

This Cummins adapter has 1/8-27 NPT Female Threads for the quick installation and is also made from high-quality brass to ensure it won’t rust over time.

All you have to do is remove the port in your Ram’s coolant system, replace it with this water temperature sensor adapter, and install the sensor.

It’s that simple.

So when it’s time to add that water temperature gauge to your 98.5-07 Dodge Ram, give us a call, send an email, or reach out to us by Live Chat and we’ll have a 5.9L Cummins Water Sensor Adapter ready for you.
