Common Symptoms
- Temp gauge climbs under load
- Coolant boil-over
- Sweet smell from exhaust (EGR cooler)
- Bubbles in degas bottle (head gaskets)
Probable Causes (Ranked by Likelihood)
- Failed EGR cooler leaking combustion into coolant Very Likely
- Head gaskets lifting due to stretched head bolts (6.0L classic failure) Very Likely
- Failed oil cooler causing overheating (6.0L) Likely
- Plugged radiator from EGR cooler flakes Likely
Step-by-Step Diagnostic Procedure
Block-test the coolant for hydrocarbons -- if positive, head gaskets are failed.
Pressure-test the cooling system -- drop with engine running points to EGR cooler or head gaskets.
Check oil cooler delta-T (coolant temp in vs out) -- >15F delta means the oil cooler is plugged.
Plan for 'bulletproofing': ARP head studs, new head gaskets, updated oil cooler, EGR cooler ($4,000-$6,000 typical).
