OCF – Oil Contamination Flush
Breaks Oil-Coolant Emulsions. Restores Cooling System Performance.
Overview
Sometimes, the worst happens: you lose an oil cooler, and now your coolant looks like oil, and your oil looks like coolant. That kind of cross-contamination doesn’t just reduce cooling capacity—it threatens the whole system. OCF is engineered to break down oil-coolant emulsions, flush out internal fouling, and restore the system to a clean, heat-transfer-ready condition.
Why It Matters
Oil-contaminated coolant changes the internal chemistry of your engine’s cooling system. Emulsions can coat surfaces, trap heat, clog passages, and degrade seals. OCF chemically separates and removes that contamination, prepping the system for new coolant and a full recovery back to Zero Hour performance.
Key Benefits
- Breaks down oil-coolant emulsions from contamination events
- Cleans internal surfaces, seals, and coolant passages
- Restores proper flow and thermal conductivity
- Prevents long-term damage from lingering oil residue
- Safe on metals, elastomers, and engine components
- Activated only when ECA confirms oil intrusion
- Vital for systems impacted by oil cooler or gasket failures
When to Use It
- After Enhanced Coolant Analysis detects oil contamination
- When a failed oil cooler or head gasket causes cross-contamination
- If coolant has turned thick, sticky, or dark from oil intrusion
- When oil appears milky or shows coolant presence
- Before refilling the system with new coolant to avoid further breakdown
How It Fits in the Program
OCF is a mission-critical component of the Royal Flush product line, deployed when Enhanced Coolant Analysis confirms oil has compromised the system. It’s not preventive—it’s a recovery protocol that gets your engine back on track after a major failure.

STEP 1
- OCF is READY TO USE.
- Record water pump pressure and all temps.
- Shutdown/Remove Surge/Day Tank Cap.
- Install 1” ball valve on each side of block underneath rail.
- Drain all old coolant.
- Fill with Flush until overflow from Surge/Day Tank. (Dilution 1:1).
- Start/Run Unit loaded at full speed with flush 7 – 14 days (10 Days Optimal)
STEP 2
- Shutdown/Remove Surge/Day Tank Cap.
- Power wash Surge/Day Tank with STH - Surge Tank Hose (while still hot and full). Let particles overflow. (15-20 min)
- Drain Flush via ball valve on each side of block underneath rail. (dispose as you would old coolant)
- *If Rust Is Present
- *Fill with deionized water until overflow from Surge/Day Tank.
- *Start/Run Unit loaded at full speed with flush until up to temp and thermostats open.
- *Drain Unit
- *Fill with RRF - Rust Removal Flush and run 2 hours at full temp.
- *Drain Flush (dispose as you would old coolant)
- Fill with deionized water until overflow from Surge/Day Tank.
- Start/Run Unit loaded at full speed with flush until up to temp and thermostats open.
- Continue to pump in water until overflow at Surge/Day Tank before opening ball valves. (2 x volume) overflow until clean.
- Inspect water pump and replace thermostats.
- Drain Unit / Fill with New Coolant*
*(Best Practice) Do not leave or run with water only.
Fill with coolant mix and 3% CRI – Corrosion Rust Inhibitor
