Intake Coolant Block Off?

Hey guys/gals need some advice.

I have a 2003 Excursion EB 6.0 with 59k miles on it! I thought I would go ahead and address all the fun issues the 6.0 can develop. None of which mine had, EGR was clear, cut oil cooler open and it looked brand new, water pump was solid, etc…

First off i added the Bullet Proof Diesel remote oil filter kit and EGR Delete. I got to looking at intakes and ODAWG sales one; which im sure most of you are familiar with. Now it doesn’t have the water passage in the intake for the EGR. I was reading that you plug up the water outlet to the intake with a freeze plug. Well when I tried to find the kit that takes care of the other end, I got the ‘Oops site cannot be found.’

Im still curious; what is the point of running fluid through the intake then EGR delete tubing for the water pump. How come I cant just plug up both ends and be done, since I dont have the factory oil cooler. I saw something about keeping OEM flow rate? So maybe there is a reason? Does the fluid have to flow through or it will cause back pressure in the water pump? Someone said to tie it into the Degas bottle.

I don’t think I can justify 800$ for this intake BUT if I can remove a possible leak and heck maybe even grind it off my intake why not. So guys/gals, do any of you have any information on this? I tried to search and found some answers but not WHY’s. Why do I need to do this? Instead of, ‘Well thought it had to go somewhere.’

Im sure I may have missed a fantastic thread that is already hitting this topic… We all do it. So if I did I apologize; just kick me out of the group!

Also I still have the truck torn apart and ive done:
Headstuds – One at a time
Took apart all injectors for inspection
BPD air-to-oil cooler w/ external oil filter
BPD water pump
Adrenaline HPOP – Stock
Updated HPOP cover
Sinister Regulated Fuel Return
Sinister EGR Delete
’08 Trans Pan
And I feel like theres more for what I bought/spent
So if you have any question about what im doing to make yours easier, PLEASE ASK. I tried to find ways to do things better and ways to remove things easier lol.

Re: Intake Coolant Block Off?

I think that is actually the return from the oil cooler. It would have went oil cooler -> egr cooler -> intake -> water pump.
I found that by searching, so it may not be correct. I am curious as well.
But if you did the cooler relocate, you may be able to plug it. Freeze plug or tap and pipe plug.

Re: Intake Coolant Block Off?

That coolant going through the intake is return from the oil cooler going back to the degas bottle. If you have the bulletproof ram air oil cooler setup, it is essentially just coolant going directly from the water pump back to the degas.

I would keep it the same, since like you said, it keeps the flow going. That is one of the only returns to the degas, so I would not eliminate it. I might consider running a coolant filter inline with it though...

Shoulda bought a Cummins.

Well you could always just run a hose from the housing straight to the degas. You would have to figure out the size difference on the two nipples though.

Re: Intake Coolant Block Off?

Yea guys im thinking i can just run two plugs in the areas labeled in my sweet Microsoft Paint photo edit!

I could plug it at the oil cooler delete OUT hose BUT im concerned it will have air in it from the drain. Dont know if that will cause issues ...

I could plug it at the block where the water goes into the oil cooler delete, but again its a place for air.

SO im thinking if you have the water pump housing off, you could plug those two places and have a clean little setup to remove all that EGR Delete crap. Less places for things to go wrong, and leak. PLUS you wouldn't have to spend money on the EGR delete.

Re: Intake Coolant Block Off?

I have mine tee-d into the heater hose above the passenger side head. I have been running it that way for over a year. No changes in deltas and the heater works great. My few classes I've had in fluids tells me this will work just fine and it does in practice

Re: Intake Coolant Block Off?

Ok I went ahead and blocked off the coolant return in the pump housing from the oil cooler with a 3/4 brass freeze plug.

Then I’ll run the coolant from the cooler delete block through a coolant filter. Figure this way I’ll have pressurized fluid to filter and if it get restricted it won’t cause any failures.

I ported my intake and welded both the timing cover and intake water passages and am going to run the coolant line off the oil cooler to a “T” in the heater core line.
