Coolant and Oil Temp Sensor

Just measure them.
If the dang hole is approximately 1/2” across, then it is 1/4” NPT. If the hole is approximately 5/8” across, then it is 3/8” NPT. If the hole is approximately 3/4” across, then it is 1/2” NPT. I could go in and on. Got it?

I just received the hmmwv crossover today. I thought the threaded port going to the water pump was going to be 1/2”NPT. But it seems bigger. Do you happen to know what it is?

Also aren’t the other ports on the top of the crossover 1/2” NPT?

That lower port is 3/4" npt. I used an adapter 3/4" to 1/2".

Top ports are 1/2". For my aftermarket gauge sending unit, I used 1/2" to 1/8" npt.

Also, the angle is different for the port to the water pump. I used a 45* molded hose.

Thank you sir!

Thank you sir!

Here's a couple pics for ya



45* hose (before adding clamps). I just cut down each leg to get the right fit


Here is the bracket I made to raise the return line and still had to tweak it a little around that one port on the crossover.


HUMVEE crossover with Paradox by Design cooling kit. You can see their Hybrid kit allows you to put the 90* fitting into the top of the crossover. I moved the driver rear cooling port sender (for the glow plugs) up to the crossover and extended the wires. Pass side crossover port is where I put my temp sending unit.

Thanks for the pictures. It was helpful. I’m still waiting on some parts but I can get to working on the bracket today. Did you have any trouble out of the transmission vacuum line that runs over the passenger side rear port for the paradox system?

also, does the desert turtle have an Instagram page?

No, no issues with the vacuum lines. You have less room to work on that side to install the new port fitting but I was just able to move things out of the way enough to get it all installed.

Desert Turtle doesn't have an IG page per say but I do post up stuff I am working on it and my other vehicles. chevy_mike68 on IG. I have been keeping most of my primary info on the build thread in ExPo.
