Direct answer
A useful cooling-maintenance record identifies the machine, the applicable schedule, the cooling components actually fitted and the work completed. Record condition and follow-up rather than simply writing “radiator cleaned.” Coolant type, service intervals and cleaning methods must come from the documentation for the exact machine.
Build a maintenance record around the installed system
Start with the complete model, serial and relevant engine identity. An excavator and a haul truck should not share an assumed maintenance specification just because both work in hot weather. Record the manual version used and the service hours. Caterpillar’s general summer-maintenance guidance identifies coolant, hoses, belts, radiator and fan as cooling-system inspection topics; it does not establish Komatsu procedures or specifications.
What to record before a service or parts decision
| Record | What to include and why |
|---|---|
| Documentation | Machine/engine identity and the applicable maintenance schedule reference. |
| Observed condition | Safely visible leakage, contamination or damage; identify the actual component and location. |
| Service work | What was inspected or cleaned, by whom, when and using which approved procedure. |
| Fluid record | Specified product and service record where available; do not identify coolant chemistry solely by color. |
| Open items | Unresolved damage, warning history or checks assigned to the service team. |
What the observations do—and do not—establish
Separate work completed from work assumed. Cleaning an accessible face does not document the condition of every part of a cooler arrangement. A record that says “all clear” without identifying the inspected area is difficult to compare at the next service. Keep consistent photographs of safely accessible locations and use the same component labels in the written record.
Turn the record into a clear service handoff
Before the next service, check that open items have a responsible person and a recorded outcome. If the machine is already overheating, use a fault record instead of treating routine maintenance as proof that operation is safe. Keep the coolant and parts labels with the service entry, and identify any uncertain specification before replenishment or replacement is approved.
Safe limits for this guide
Allow the system to reach the condition specified in the manual before access. Do not remove a hot pressurized coolant cap or work near moving fans and belts. Cleaning pressure, direction and access requirements are machine-specific.

This is a general service-planning guide. The linked machine pages organize identification information; they do not make the workflow a model-specific repair procedure.
Frequently asked questions
Can I use the same schedule for a truck and excavator?
Only if the applicable manufacturer requirements establish it; do not assume equivalence.
Does coolant color establish compatibility?
No. Use the specified product requirements and documented identity.
Does this guide provide cleaning pressure?
No. Obtain the approved method for the installed cooler arrangement.
