Recipe - Ford 6.0L Power Stroke Diesel

Reliability build

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

Preventive baseline for a stock, healthy 6.0 with no current failures. Addresses the known weak points that are cheap now and expensive later, without opening the cooling system or the heads. Do this before adding any power.

Parts

6.0L Power Stroke Fuel Pressure Regulator "Blue Spring" Upgrade Kit - raises marginal fuel pressure ~10 psi for injector longevity; the single best cheap preventive (qty 1)
6.0L Power Stroke Fuel Filter Set (HFCM lower + secondary/upper) - fresh filters so the blue spring reads true and the lift pump isn't starved (qty 1)
6.0L Power Stroke Degas Bottle Pressure Cap - a failed cap mimics head-gasket symptoms; a few dollars (qty 1)
6.0L Power Stroke Coolant Filtration Kit (spin-on) - stops silicate/sand debris from clogging the oil cooler and killing the EGR cooler - the root cause of most 6.0 failures (qty 1)
Ford Specification Gold HOAT Coolant (6.0L Power Stroke) - fresh Ford-spec gold coolant with the new filter (qty 1)
6.0L Power Stroke Battery, Group 65 (Ford BXT-65-750, paired) - load-test both; weak batteries kill the FICM. Replace if marginal (qty 2)

Install order

load-test both batteries; clean terminals; replace if weak
install coolant filter kit; then flush and refill with fresh HOAT coolant
replace both fuel filters
install blue spring in the fuel pressure regulator; verify pressure with a gauge (target set by SME)
replace the degas bottle cap

Expected outcome

Removes the cheapest, highest-value failure risks. Does NOT bulletproof the truck - the EGR cooler, oil cooler and head gaskets are untouched.

Do not

do not use a coolant filter element that adds SCA (supplemental coolant additive) - the 6.0 uses gold HOAT coolant
do not skip the fuel pressure gauge check after the blue spring
do not add a tune or power modules on top of this recipe

Parts budget

About $330 in parts, plus parts we have no price for. 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 $330 plus parts we have no price for: 6.0L Power Stroke Fuel Pressure Regulator "Blue Spring" Upgrade Kit (about $90) + 6.0L Power Stroke Fuel Filter Set (HFCM lower + secondary/upper) (about $85) + 6.0L Power Stroke Degas Bottle Pressure Cap (about $15) + 6.0L Power Stroke Coolant Filtration Kit (spin-on) (about $140) + Ford Specification Gold HOAT Coolant (6.0L Power Stroke) (no price yet) + 2 × battery (no price yet)

DIY or shop: All DIY with hand tools and a weekend. The coolant filter kit is the only slightly involved part.
