Frequently Asked Questions About Ford F650-F750 Truck Coolant Reservoirs

Will these coolant reservoirs fit my specific F650 or F750 model year?

Our coolant reservoirs are designed to fit Ford F650 and F750 trucks from 2000 to present. However, there are variations between model years, particularly between pre-2015 and post-2015 models due to engine changes. Always verify your truck's specific engine type (6.7L PowerStroke, 6.8L V10, or Cummins options) before ordering. If you're unsure, contact us with your VIN number and we'll help confirm the correct reservoir for your truck.

What's the difference between OEM and aftermarket coolant reservoirs?

OEM reservoirs are manufactured to Ford's exact specifications and typically feature thicker plastic construction and precise mounting points. Aftermarket options can offer similar performance at a lower price point, though material thickness may vary. Both types should handle standard operating pressures (15-20 PSI), but OEM reservoirs generally offer better long-term durability in extreme temperature conditions. All reservoirs we carry meet or exceed DOT standards for commercial vehicles.

Can I install a coolant reservoir myself, or do I need special tools?

Most coolant reservoir replacements can be completed with basic hand tools in 30-60 minutes. You'll need standard wrenches, pliers for hose clamps, and a drain pan. The main challenges include accessing tight spaces in the engine compartment and properly bleeding air from the cooling system after installation. We recommend having a pressure tester to check for leaks after installation. Always allow the engine to cool completely before starting work.

How do I know when my coolant reservoir needs replacement?

Common signs include visible cracks or stress marks on the reservoir body, coolant stains around the cap or seams, difficulty maintaining proper coolant levels, or a sweet smell in the engine compartment. F650-F750 trucks operating in extreme temperatures or with high idle hours may need reservoir replacement every 5-7 years. Inspect your reservoir during regular maintenance checks, paying special attention to the area around the cap and lower mounting points where stress cracks commonly develop.

Are there different reservoir sizes for different engine options?

Yes, coolant reservoir capacity varies by engine type. The 6.7L PowerStroke diesel typically uses a 2.5-3 gallon reservoir, while the 6.8L V10 gas engine uses a slightly smaller 2-2.5 gallon unit. Cummins-equipped trucks may require specific reservoirs depending on the engine series (ISB, ISC, or ISL). Using the wrong size can lead to improper coolant levels and potential overheating. Always match your replacement reservoir to your specific engine configuration.
