Recipe - Ford 6.0L Power Stroke Diesel

Tow Reliability build

Reliability tier: aggregated - verify before ordering, see /disclosure/

For a stock-power 6.0 used to tow, with no full bulletproof budget yet. Focuses on the failures that strand you on a grade: hard hot-start (STC), FICM, cooling wear, and diagnosing the oil cooler before it takes the EGR cooler with it.

Parts

6.0L Power Stroke STC Fitting Update Kit (high-pressure oil rail) - the #1 hot-restart failure on 2004.5+ trucks; strands you at fuel stops (qty 1)
6.0L Power Stroke Standpipe & Dummy Plug O-Ring Kit - same job, related HPO leaks and aeration (qty 1)
6.0L Power Stroke IPR Valve (Injection Pressure Regulator) with screen & o-rings - clean or replace with new screen/o-rings while in the HPO system (qty 1)
6.0L Power Stroke FICM Power Supply (rebuild board, higher output) - proactive - a FICM failing under a towing load / heat is a roadside no-start (qty 1)
6.0L Power Stroke Water Pump - wear item; failure under tow load = overheat (qty 1)
6.0L Power Stroke Thermostat - done with the water pump (qty 1)
6.0L Power Stroke Coolant Filtration Kit (spin-on) - protect the coolers (qty 1)
6.0L Power Stroke Engine Oil Cooler (valley, oil-to-coolant) - ONLY if the EOT-ECT delta test shows restriction (see Engine oil cooler clogging / failure); otherwise defer to a bulletproof job (qty 1)

Install order

run the EOT-ECT delta test under load; if restricted, the oil cooler moves from optional to required and this becomes a partial bulletproof job
STC fitting + standpipe o-rings (+ IPR service while open)
FICM power-supply upgrade
water pump + thermostat + coolant filter + fresh coolant

Expected outcome

Removes the common roadside-failure modes for a towing truck at stock power. Not a full bulletproof - if the oil cooler is already restricted, do The classic emissions-legal 6.0 bulletproof at stock power, using OEM-style... instead.

Do not

do not replace the EGR cooler alone if the oil cooler is restricted - do both
do not tow heavy on a truck with a known-failing FICM or STC fitting

Parts budget

About $1,300-$1,650 in parts. It depends on what the diagnosis finds; each option below is what you buy together. Prices marked "at Dave's" are Dave's Auto Center's, the same as in his store; the others are approximate prices from OEM and maker catalogs, rounded (a manufacturer's list price can run higher). Parts only, no labor.

about $1,300: 6.0L Power Stroke STC Fitting Update Kit (high-pressure oil rail) (about $150) + 6.0L Power Stroke Standpipe & Dummy Plug O-Ring Kit ($236.67 at Dave's) + 6.0L Power Stroke IPR Valve (Injection Pressure Regulator) with screen & o-rings (about $440) + 6.0L Power Stroke FICM Power Supply (rebuild board, higher output) (about $150) + 6.0L Power Stroke Water Pump (about $100) + 6.0L Power Stroke Thermostat (about $55) + 6.0L Power Stroke Coolant Filtration Kit (spin-on) (about $140)

DIY or shop: STC fitting and FICM power supply are DIY-friendly; the water pump is moderate. Oil cooler (if needed) is a shop job.
