Replacing Thermostat on a Cummins 5.9L

[@sexyfiretoes8402]

channel locks work good for the hose clamp aswell if you don't have the special tool

Thanks for the video. I understand a genuine Cummins thermostat is a good way to go for reliability and flow area but the price was astronomical 122 CAD, so depending on your budget… also my coolant is orange/red in my 2006. Any idea if something changed between our model years?

Maybe back flush the coolant system.

There's no reason to remove the radiator hose.
