What coolant do you recommend? I've found a leak on my truck (see pics) and need to re-fill the coolant level. Not sure why this leak developed???

Get whatever the factory spec recommends, most any good parts house will have it.
However I would suggest using distilled water with orange coolant. Looks Dodge to me but I'm a tard.

Get what the factory recommends for coolant, your local Dodge dealer or diesel shop should have what you need. Dodges run a similar lifetime coolant that is good till 100,000. It may be time to get a good flush done and refill.

Looks like that hose is leaking, did you get it replaced?

I run Royal Purple in everything in my truck. I love it. To be honest I did notice a diff between the stock and RP. NOT much to say "Shit that much" but about 10° diff in EGT's.

I had the same leek I just tightened the hose clamps good to go, this is a known problem on the 5.9s.
