To replace or not to replace...

[F250SixOH]

Well I installed my new thermostat last week and the ECT stays at 188-190 on the highway. I monitored my temps for my four hour drive down to school doing 80mph the whole way. ECT was 188-190 and EOT was 206-207. This seems a bit far apart but I just wanted to get opinions. If replacement is needed, I need to get all of the parts ordered. So far:

Parts:
EGR delete $135 Ebay
Oil Cooler $299 XDP FO3C3Z-6A642-CA (Does this come with the screen?)
STC update kit $38.45 Tousley 4C3Z9B246F
Turbo hardware $7.44 Tousley 3C3Z-9T514-AD
Intake gaskets (2) $18.10 Tousley 3C3Z-9439-AA
Turbo return tube $20.90 Tousley
Total so far: $518.89

Fluids:
5 gallons rotella 5w40 (walmart)
10 gallons distilled water (walmart)
3 gallons CAT ELC-1 coolant (NAPA)


Any other parts I will need? This is going to be a fun Christmas break for me

this not an answer to your post more of a question aren't you supposed to look at the temp difference at 60 to 65 mph? thinking that 80mph might change that. Someone will jump in and help here

I don't know if this falls into the "absolutely necessary at this moment" category, but if you've torn down your engine that far you might want to see if you need the updated turbo drain tube. It's only around $20-30 or so.

Forgot about that. Do I need anything else for the STC replacement? Also I thought about the blue spring upgrade for my fuel system but when I looked there was a blue dot painted on the cover Not sure if this means that it is already installed or not.

I would look into Tousley for the rest of the Ford parts as well. The oil cooler is only $215-$220 from them etc.

Just called Tousley. Oil coolers are out of stock and they didn't know when they would get more. Guess I'll be ordering elsewhere.

3C3Z-6A642-CA $213.84

I believe someone else recently posted something about a blue dot on their fuel pressure regulator housing (if that's what it's called) and it seems like when they pulled it off it was still the old spring. Not positive, but I'm not sure that means it's been changed.

I was curious about that. I couldn't find the thread to see if the guy had found out if it was in fact a blue spring or not.

Well my buddy calls me first thing this morning. His 6.0 popped HG's. Looks like I will be towing him down to Trucks Unlimited. I have heard good things about them on this forum and told him to give them a call tomorrow. Almost makes me just want to drop my truck off with them as well Decisions decisions...

Slow the truck down to about 60-65 and see what the temps are. I wouldn't change all that out just yet...I too have parts waiting to be installed, but due to the nature/time involved I want to make absolutely sure that the truck needs it.

The blue spring mod is super simple...do the 6.4 banjo bolts along with it.

Just my .02 FWIW.
