Coolant flush for Mogul drivers: Mae Anne Avenue, 7 minutes

Mogul is small, about 1,050 people in 474 households, but it is well stocked with vehicles: 2.85 per household on average and 85.7 percent of homes with two or more (Census ACS 5-year 2024). That matters for coolant more than for most fluids. Coolant ages by the calendar, and the trailer truck, the weekend car or the camper parked beside the house is aging its coolant whether it moves or not.

Time, not miles, is what runs out

AAA lists conventional green IAT coolant at about two years or 24,000 miles and the long-life OAT and HOAT types at about five years or 50,000 miles, some makers allowing up to ten years or 150,000. Notice the years. A vehicle that covers 3,000 miles a year will hit the time limit long before the mileage, and the corrosion inhibitors in the coolant wear out on the same schedule either way.

So the household with three vehicles usually has one that is overdue and nobody noticed. Bring them in together; a freeze-point reading on each takes a minute.

I-80 along the river, and what it asks of a radiator

Mogul sits on the I-80 corridor where the Truckee River leaves the canyon. Head west and the interstate starts its long climb toward Donner Summit; head east and you are in Reno, where the airport station averages 65 days a year at 90 F or hotter (NOAA 1991-2020 normals). A truck towing a boat or a camper up that grade on an August afternoon is the textbook severe-service case: high load, high outside temperature, thin air at altitude.

Winter is the other side. The same station records about 122 freezing nights a year. Healthy coolant at the right mix protects against both, and that is the whole point of the service.

Seven minutes to the bay

Take I-80 east to the McCarran Boulevard exit or follow West 4th Street into town, turn north and pick up Mae Anne Avenue; the service center is at 6100 Mae Anne, about 7 minutes from Mogul with no traffic. Open Monday through Friday 8 to 5 and Saturday 8 to 4, closed Sunday, (775) 787-1000.

How the flush is done

• Refractometer freeze-point reading and a look at color and clarity, shown to you
• A written estimate first for anything over fifty dollars (Nevada NRS 487.6875); you decide
• Radiator drained, and the block where the engine allows it
• Refill with the manufacturer's coolant type at the correct ratio, never a guess by color
• Air bled from the system, heater and gauge checked, cap and hoses inspected
• Old coolant collected for recycling
