Mine runs cooler to around town stop and go

But the true test is 60-65mph going steady on the freeway leval ground take the temps when it reaches the steady high temp

this time of year Im at 4-6 max spread at 65mph

but dead middle of summer it gets 6-8* spread

I did see a spread of 10* this summer but ambeint temp was 110-112*

But with an EGR deleate the spread isnt as important but I do watch it cuz a plugged oil cooler would still be Bad JUJU

 

Ok that buts me at the 20-22* delta then, not good news . Looks like I'm going to be flushing sooner then i hoped. Have to wait until Tuesday for dealer to open to get t-stat. Debating on to order coolant filter or make my own. Driveway is going to be a skating rink.

 

I made my own coolant filter I didnt like any of the kits out there


shure they look nice but they all reduce down to small return lines and like plumbing you can only flow as much as your smallest fitting allows

I kept all lines the same size and tyed back in at the heater return line (instead of the small line)

then I drill the Filter out in the middle where you see that plastic with the 5/32 hole I drill it to 1/2 inch
so the only thing that regulates the flow is the filter media but I change it fairly often for the first few
I bet Im filtering 2-3 times the amount of coolant as the kits do

heres some pics of what I did



the filter and bracket I made to hold it all



and then here is the return line kept it the same size as what I started with at the heater supply and droped it back in the heater return line under the coolant bottle

 

That's what I was after, if you thought it was casting sand or silicate goo. My truck has a 12-15 degree delta, getting ready to do a BPD EGR and new OEM OC. I flushed my truck at 20k when I did the ARP studs and HG's, and recently again at 42k.

I have a friends truck with 96k, never had the coolant flushed, getting ready to do it as well.... has a 30 degree spread! Curious to see what I find when I cut open both coolers.

Take care Bud.

BLADE35 Once again THANK U. Is the base from napa and filter a 4070. Also are those 1" x 1" x 3/4 " pex tee's. This is what I think I'm going to use.

 

yes base is a NAPA and filter is the NAPA 4070 uncharged

I got the hose from NAPA to 10 feet of it

and they are the PEX tee's I will have to go measure them but I think my coolant filter lines are the same size as the Heater Supply lines I tried to NOT Reduce anything

and Honestly I had about the same money into it as a premade kit 100.00-120.00
But I just didnt like how those kits reduce down so much tthought my odds would be better the more coolant I could filter faster

heres a cross referance for filters so whatever you like or can get cheap

Tommorro I will double check the size of PEX fittings and hose size

 

Great info. I appreciate all your help. Don't know when i'll be able to do the flush any time soon. But i'm kinda dredding it though. 50/50 chance if i can just flush or will have to do oil cooler & egr cooler. If so i'm going with BPD cooler kit. I'm hoping this w/e weather is soppose to get back up to the 40*. I have a heated garage but only have about 6" in front & back of truck . difficut to do anything to it. plus don't want the big mess.

 

Oh ya no doubt its a big mess and best in warmer weather

then you have to take into consideration that you may plug that oil cooler worse by stirring up all the junk inthere
But then on the flip side a blown egr cooler is a mess and a popped oil cooler is the worst case possible

heres some good ideas for flushing in this thread especialy if the oil cooler does plug

SOME GREAT IDEAS ON OIL COOLER BACKFLUSH
https://www.ford-trucks.com/forums/1...ch-advice.html

also if you have a round egr cooler that may buy you some time they are built better

 

We'll i did the coolant flush with vc-9. The first 5 gallons was alittle discolored . I flushed it for an hour and was as clear coming out as going in. Thought that might be good news . So i replaced t-stat, backflushed heater core. Added antifreeze ( zerox witch is clear I didn't care for that ) topped off . Drove highway flat ground about 50 miles , 65 mph. Delta was 18*-20* ( previous 20*-22* ) helped a little but still plugged. So i'm going to replace oil cooler and egr cooler. Thinking about BPD egr cooler (any suggestions), stc fitting ,icp pigtail, exhaust manifold gaskets (leaking alittle), glow plugs while i'm in there .Possibly BPD water pump. Up-graded turbo tube, & Coolant filter. Any other recommended up -grades while in this deep don't want to have to work on it for awhile Thanks.

 

Since you have an 05 do the standpipes and dummey plugs to

The Glowplugs in these seam good so you might could scratch that from the list
And if you dont scratch GP from the list add 2 GP harnesses cuz they will more than likely break. If your very very careful you might get them off without any damage to the GP harness

Ya those oil coolers are hard to flush out when they get clogged up the junk is just to caked in there

 

Ok added to list. Will be tearing down this spring just getting a list for now in town delta 9*-12*. Also is it normal to see alittle oil in the cold air tube from between the crankcase tube to the turbo and from the turbo to intercooler tube . Just a light film and alittle puddle in the hose on the outlet of the turbo where the hose fits over the turbo.

 

yes alittle oil in the air intake tubes and CAC tubes is normal. This is way some do the CCV reroute.

Do you have the square or round egr coolers??

And just keep in mind if your out of spec ECT vs EOT on the road test at the 65 mph the egr cooler is not getting the proper amount of coolant.

So regaurdless of weather or not your in town and the spread is within spec around town the egr cooler is still NOT getting the Proper flow of coolant. The egr cooler is still deprived of coolant. Your just not working the engine hard enough to drive the spread out of spec.
There is no test for the oil cooler for around town, around town is stop and go diffrent speeds Basicaly there are to many Varibles around town. this is why we test at Hwy speeds because there are less variables its more consistent and acurite of a test

but also keep in mind that 20* spread ECT vs EOT was the old spec
Now Im not shure but I think Ford bumped the max sread to 15* once all the square EGR coolers were Failing alot

Once it Failed the road test at a steady 60-65mph The oil cooler is plugged and has Failed the Test and is a Bad part.IMHO

 

Ok thanks. Is there a company that would sell all the listed items so I don't have to pay a ton in shipping from ordering from several company's. I really haven't had a change to search for parts yet. Hopfully I can tonight. Any recommended company's. Thanks

 

I would get all the OEM stuff from www.partsguyed.com

What you save on the oil cooler alone will be around 100.00+

and then get a egr deleate from whoever or a BPD egr cooler

I have square. Sorry i can't seem to get this web site to copy . I thought it was interesting on standpipes . TECHNICAL BULLETIN APTB-03/08R1. Do you replace the standpipes and dummy plugs or just o-rings. By looking at this site I'm going to replace the sets. Also debating on delete or not. Whats the delta difference between delete or (BPD or stock) cooler.
