Another Possible EGR Cooler/HG Problem

[Harleyjim]

Have an 08 job 1 F250. 130k on the clock. Been loosing coolant and can smell a leak on the drivers side. No visible leaks anywhere that I can find. Been under and on top of engine 20 times running/not running. Hot/cold, you name it.

Have dpf/cat gone and DPF-R delete with economy tune installed. When I drive it hard for just a 1/4-1/2 mile it will blow coolant out the degas bottle. When sitting idling it will bubble up a little air and coolant from the hose coming from the hose coming from erg cooler not a constant flow of coolant (hose on front left of degas bottle)Also, no white smoke from exhaust. No water in engine oil.

I have not owned this truck very long. Have done a lot of reading and searching on the forum and still cant come up with the problem for sure. Is there a diagnosis I can perform to rule out one or the other?


Any help would be greatly appreciated.

Thanks,
Jim

Also, cooling system will stay pressurized after sitting all night. I would think it would bleed off with any kind of leak or bad gasket.

sometimes if you fill the degas bottle too much it will puke a little coolant. Also maybe try and buy a new degas bottle cap. Maybe the current one is not holding enough pressure. Since you are out of warranty it might be worth it for you to do the egr delete and rule out that possibility.

Have a brand new degas cap. May try the egr block to rule that out. Don't think it is filled to full because it will puke even if it is very low in the bottle.

well if there is no water or fuel in the oil then my guess would be a bad egr cooler. Take a look at the dirty diesel egr delete. It comes with the intake elbow also

Just ordered a couple block off plates. Be here tomorrow. If that fixes my problem then I will go with the egr delete. If it doesnt then I assume I have bad head gasket......

Thanks 04hdfatboy for help. I hope it is egr cooler.

What would be the least expensive tuner I could get to turn off egr and light?

This is a good one for the money. IMO h&s is top notch!

Its not very common for the head gasket to go bad on the 6.4. I would put my money on a bad egr cooler. Probably the horizontal one. Let us know if that fixes your problem.

[Harleyjim]

I will let you know for sure. I like to read on this forum about what it took to get a problem fixed so others will know.

Thanks,

Well, I put the egr block off plates in and no change!! Still pukes coolant out the degas bottle cap on hard acceleration.

Any ideas??
Do you think it is head gaskets or is there something else it could be??

Thanks,
Jim

The upper radiator hose has leeks and ford knows this! Buy a new upper radiator hose and replace. Easy to do. To find the leak, pressurize the system and it will leak like a SOB from the lower end of hose.
