Yes they do OEM
Today did the 5th oil change since installing the 6.2
One before start up
another at 800 miles on the oil
another at 1200 miles with MM oil (trans fluid)
another at 1500 miles *** oil is still filthy***
another at 2300 miles
Oil filters done with the oil changes. I should have cracked one of the valve covers before the engine install to see what was going on under there. Was in too much of a hurry to get the engine done. Damn

Man, those crimped radiators have always been problematic with the seeping end tanks. I remember problems with those back in the early 90s. Some shops had a crimp tool and would just re-tighten the crimps on it.

Mine was cracked, so I went with Mishimoto. After 9 months, it's already cracked and leaking...
Lol, mine is so minor, I’ve left it for 6 years.....

***CAUTION*** I do my own stunts!
I always look for upgrades when I have to replace something.
Haven't decided on one yet.
I like this one...

Little pricey but probably better quality.
Wtf!?! Do not like.

No idea! The 13" trailer tires aren't even E-rated and take 35psi. Between the generator part, diesel engine and full tank of fuel, my really rough guess is 700 lbs.
It's just like this one:

Same here! I'll compare that one. Thanks for the link.
Your Mishimoto is cracked? Details please and pics too.
Yeah, this was going to be my go to.. [emoji45] I do want to upgrade from stock when I replace mine.
It needs more diagnostics, but it looks cracked to me. No leaks from hoses. No coolant stains starting from any hoses.
But this area of the radiator is saturated orange and i see fluid underneath.
Smelled coolant for weeks.

the local radiator shop here, that has been here for decades... told me the aluminum radiators always leak they had never seen one that didn't and they didn't recommend any brand but they will sell one if you really want it lol.

Might be a little hard to get in there with the aluminum spool gun nozzle

I went thru that a couple times, had it re-crimped 2-3 months later, leaking again
I know I will be chastised for this but that stop leak aluminum powder shit works good. I used it my whole life never had any ill effects from it for small weeps or leaks.
Oh I figured it would have to be pulled out either way to actually find where it is leaking. I got my first MIG aluminum setup last year so I am trigger happy with it lol.

Yes sir. If you live anywhere it gets cold enough that requires salt on the roads it won’t be long before your wheels end up bleeding worse or the chrome starts flaking like others have mentioned. I got tired of filling mine up whenever the temp dropped, so I ditched the 22” chromes and went aftermarket.
