2019 International MV Coolant Capacity & Type: A Master Technician's Guide
Your 2019 International MV typically holds between 30 to 40 quarts (28.4 to 37.8 liters) of coolant in its cooling system.
Quick Answer
- Total Cooling System Capacity: 30-40 quarts (28.4-37.8 liters)
- OEM Coolant Spec: Predominantly OAT (Organic Acid Technology) or NOAT (Nitrited Organic Acid Technology), extended-life coolant, typically red, pink, or orange in color. Always refer to your owner's manual or the International service manual for the precise specification, potentially Navistar MPAPS B1 Type II or similar.
- Mix Ratio: 50/50 prediluted or 50% concentrate / 50% distilled water.
Capacity by Engine Option
The International MV series typically offers a Cummins B6.7 engine. The exact coolant capacity can vary slightly based on specific chassis configurations, radiator size, and the presence of auxiliary heating/cooling systems.
| Engine Option | Approximate Capacity (Quarts) | Approximate Capacity (Liters) |
|---|---|---|
| Cummins B6.7 | 30-40 | 28.4-37.8 |
Flush Interval
Maintaining your coolant is crucial for the longevity of your engine. The flush interval depends on the type of coolant used and operating conditions.
- Normal Duty: For OAT/NOAT extended-life coolants, the typical flush interval is 5 years or 150,000 miles, whichever comes first. Always check your specific coolant manufacturer's recommendations.
- Severe Duty: If your 2019 International MV operates under severe conditions (e.g., heavy hauling, frequent idling, extreme temperatures, dusty environments), it is advisable to reduce the flush interval to 3 years or 75,000 miles, or as recommended by Navistar for severe service.
How to Refill & Bleed
Properly refilling and bleeding the cooling system after a drain or flush is critical to prevent air pockets that can cause overheating. Here
