To verify coolant acceptability, submit a sample for coolant analysis every 300,000 miles (480,000 km), three (3) years, or 5,000 operating hours, whichever comes first. Submit the sample in a DDC Power Trac Coolant Test Bottle. Required part numbers are listed in Table 38. 10. Do not use the following in Detroit Diesel engine cooling systems:
Soluble oil Coolant Life of OAT Coolant — A properly maintained OAT coolant may be operated 600,000 miles (960,000 km), four (4) years, or until overhaul, whichever comes first. At this time the system must be completely drained, thoroughly cleaned, and refilled.
