LLY: Type/Brand of Engine coolant

[Wyley87]

I did a a search before posting and couldn't find anything on the subject.

I have an 06 LLY with 75k on the clock and need to do a cooling system service as well as change both thermostats. I know the truck came from the factory with Dexcool but I read somewhere where Dexcool is not really made for diesel engines. What coolant should I use?

dexcool is fine. Maintenance is key.

Isn't the just a drain plug on the driver side front of the engine?

there is no radiator drain plug so you pop off the hose and it goes everywhere

 

[jraymer]

makes me wonder why they stopped putting a plug in the damn radiator??

 

[KEVINL]

to save 1 cent

I knew about there being no drain plug on the rad but I thought I read on here in the tech section that there is one on the drivers side of the engine.

yes that is still there

That plug will still blow coolant in ten different directions when you open it. If you happen to have one of your I/C pipes off, use that over the drain to funnel the coolant into your pail.

How many gallons is in the system? I'm wanting to do the same thing on my 04.5.

Mix it 50/50. I use two gallons of coolant but I am in Florida. Should still be good in colder climates though.

Well I'm in Texas so I will be mixing 50/50.

So I need 2 gal straight coolant and mix it with 2 gal water.

If your completely empty it takes around 5 gal total.

Wtf, mine has a drain in the pass side of the radiator did they change that for 06?

06+ bye bye simplicity

I hate Dexcool, it corrodes easily and is very susceptible to electrolysis. I use Power Cool by Detroit. It's stable, and I mix 60/40 - water/coolant.

 

[Wyley87]

I got a little 3x5 pan so I'm hoping to catch most of it lol.

I've always been kinda leery of dexcool also. But being the first diesel I've worked on I wasn't sure on type of coolant. I'd like to just put green in it cuz that's what's in the rest of my cars/trucks.
