How to Specify the Fluid Diligence Pack
- Recent oil analysis — wear metals, soot, fuel dilution, viscosity, water; dated samples tied to serial numbers.
- Coolant chemistry — freeze point, inhibitor reserve, pH, evidence of oil contamination or electrolysis issues.
- Filter and change records — intervals claimed versus evidence; gaps are data, not vibes.
- Hour meter honesty — reconcile meter photos with service stamps and sample dates.
- Storage history — fogging, desiccant, and whether the set sat dry or wet for seasons.
- Independent resample right — ability to pull fresh samples under inspection participation discipline after NDA and qualification.

What to Inspect Beyond the PDF
Look for oil leaks at seals, coolant stains at water pumps and hose junctions, sludge in fill necks, and mismatched filter brands that hint at chaotic maintenance. Radiator fins crushed in inland transport matter — see inland transport of used diesel packages. Canopy photos without dipstick access are marketing, not diligence.
What It Costs to Run — Only
Duty shapes fluid stress: telecom towers with light loads and frequent starts differ from mining camps and hospital standby. Contrast telecom towers, mining camps, and hospitals standby.
Common questions
Is a six-month-old oil report enough?
It is a start, not a finish. Prefer recent samples and the right to resample under inspection.
Can coolant look fine while oil is failing?
Yes. Treat coolant and lube as separate evidence streams. Cross-contamination (oil in coolant or coolant in oil) is a stop-the-buy signal until explained.
Do black-start and peak-shave packages need the same diligence?
Yes — critical roles amplify fluid risk. See black-start packages and peak shaving .

Owner Checklist — Fluids Before Deposits
1) Demand dated oil and coolant reports tied to serials. 2) Shortlist on https://www.uspeglobal.com/inventory/. 3) Reserve resample rights under inspection discipline. 4) Decide refresh vs overhaul vs walk-away before civil freezes. 5) Keep sampling alive under O&M after COD.
