Radiator capacity for a 1998 ford e-350 5.4 v8?

There isn't a single definitive radiator capacity for a 1998 Ford E-350 with a 5.4L V8. The capacity can vary slightly depending on the specific configuration of the vehicle (e.g., extended cab, chassis cab, options like towing packages).

To find the exact capacity, you should:

* Check your owner's manual: This is the most reliable source. The manual should specify the coolant capacity for your specific vehicle.

* Look for a sticker on the radiator or in the engine bay: Sometimes manufacturers place a sticker indicating coolant capacity.

* Consult a Ford parts dealer: Provide them with your vehicle's VIN (Vehicle Identification Number) for the most accurate information.

* Check a reputable online parts database: Websites like RockAuto or AutoZone allow you to search by your vehicle's year, make, model, and engine to find specifications, but these are not always completely accurate.

Without your specific vehicle information, I cannot give you a precise answer. Expect the capacity to be in the range of 12-16 quarts, but this is just an estimate. Always refer to your owner's manual or a Ford parts dealer for the precise amount.
