Rear differential axles temp sensors

There should be an extra plug on the pumpkin for a sensor, you would need to install separate gauges for each of them.

 

Dont waste your time. Unless you just like watching needles move there is no point. With 425hp your rears will never get hot enough to worrie about.

 

If worried get a temperature gun and check temps after a good pull.. it’s useful for checking hubs too

 

How does horsepower affect the rear temps? I've got a 550hp truck that doesn't go above 170 on either differential. I've also got a 2.8L Duramax that has hit 260F climbing mountains with a load.

 

I have 550hp, and mine never go over 100. They’re both broke

 

A 2.8L Duramax. When did that come to market?

 

Its porportionat.

Your truck at the very least is going to have 40;000 rears . Industry standard.
With 425 hp and I'm guessing 1650 torque at the most there not going to get hot. With your specs I'm perty certain you'll never going to gross over 80,000 ever. So yes it's not going to matter much.

 

I think like 2016 on the Canyon and Colorado. I've got a 2018 Colorado and the engine temperature doesn't even get above 190F no matter what I do. But the transmission temperatures go crazy once I put like 4000 or more behind it and start climbing grades. It's the opposite of how my Volvo with 550hp and 3.08 rears acts. The engine temperature gets upwards of 240F on extended pulls at full throttle, while the rears don't pass 170F.

I think the Colorado has 3.42 rears.
