Can you post the locations to Drain the Radiator and the Intercooler?

Yes the top reservoir is for the low temp circuit which is the intercoolers. The turbos are fed by the engine cooling circuit.

The blue/pink coolant, we could have 2 identical cars and they shipped with different coolant, I never did come up with a real source as to what the logic was, either coolant will work just fine, but if you mix them it turns a really ugly color, just stick with what is in there.

I've never had to do a 278 water pump, saw a few 276 leaks at the base gaskets due to corrosion of the aluminum though. But we did hundreds of sets of turbo coolant hoses on cars with 40k+ miles. I'd bet money your lines are leaking.

bump.. Cannot locate any drain valves for Radiator or Intercoolers to do a Antifreeze change. Anyone have photos or docs?

Pretty sure there isn't' one for the intercooler circuit. Radiator has one on the lower left corner. Will make a tremendous mess as it's not setup for a drain hose and it's above all the plastics.

Why are you changing coolant?

I'm at 45K, I like to do service on certain items myself even though they say you can go 100K on the fluid.
Do you have a photo or exactly where and what the drain would look like? Is it on the Front, Side, Bottom? What type of Drain Screw/Bolt. Thanks, any info would be appreciated.
For the Intercooler, I do a Drain and Fill of the reservoir every 2 years, its such a small amount, doesn't cost much. I do a brake Flush every 2 to 3 years on all my vehicles with the Motive System. Very easy process. Looking to do the rear diff next.

Looks like you may have something here. Upon doing the water pump replacement they saw that the coolant lines were weak as well so another day for the coolant lines to be replaced. Also getting the control arm replaced due to failure.

This is what i come up with. Good luck

Thank You!

Those coolant lines go into the housing for the water pump so I would bet they broke when trying to remove then. Glad you were able to get the new turbo coolant lines. Hopefully they replace all of them.

Looking for more specifics on these turbo coolant lines, but not finding them in the parts catalog I normally use ... https://www.mboemparts.com/v-2016-me...e--4-7l-v8-gas

RockAuto shows four lines, two supply (R and L) and two return. One has a picture that appears to be a metal pipe with a section of black material that must be the failure-prone plastic.



Are there just four of these? Does anyone have the actual part numbers?

As always, thanks!

But is the diagram showing refrigerant lines or coolant?
