Orange County summer heat is hard on commercial trucks, so we service cooling systems completely at our Yorba Linda shop to keep Anaheim fleets off the shoulder of the 91. We pressure-test, flush, and refill the system, replace radiators, water pumps, thermostats, and hoses, and find leaks before they strand a truck.


## What this includes
- Cooling system pressure test to locate external and internal leaks
- Coolant flush and refill with the correct extended-life specification
- Radiator, charge-air cooler, and fan-clutch replacement
- Water pump, thermostat, and hose replacement
- Head gasket and oil-cooler leak diagnosis for unexplained coolant loss
- Cap, overflow, and coolant-sensor testing
- Heat-soak road test to confirm stable temperatures before route return

## Who it is for
- Anaheim fleets watching temperature gauges climb on hot Orange County afternoons
- Operators topping off coolant or spotting puddles under a parked truck
- Fleets on preventive schedules who want coolant serviced before the summer peak

## Pricing
Flush and pressure test sit near the low end; radiator and pump jobs reach the high end, with totals confirmed in writing after an in-shop assessment. Mechanical labor billed at $260 per hour, diagnostics at $285 per hour.

## FAQ
### Why does my commercial truck overheat in traffic?
A weak fan clutch, clogged radiator, tired water pump, or low coolant all spike temperatures in stop-and-go Orange County traffic. We pressure-test to pin down the exact cause for Anaheim operators.

### How often should coolant be flushed?
Most commercial trucks need extended-life coolant service every two to four years or by mileage. We check condition and confirm the right interval for your Anaheim duty cycle.

### Can you tell if a coolant leak is internal?
Yes. We pressure-test and check for oil and coolant cross-contamination to separate an external hose leak from an internal head gasket or oil-cooler fault.
