Size of cooling system on 2002 ford f150 with a 4.6L?

There's no single answer to the size of the cooling system on a 2002 Ford F-150 with a 4.6L engine. The capacity depends on several factors including the specific trim level (some options might add or remove components affecting capacity), and whether any modifications have been made to the vehicle.

To find the exact coolant capacity, you need to consult your owner's manual. That manual will specify the exact amount of coolant your specific truck requires.

Alternatively, you can:

* Check online Ford parts websites: Enter your VIN (Vehicle Identification Number) to find a parts diagram and specifications for your specific truck. This will often list the coolant capacity.

* Consult a Ford dealership: A service advisor at your local Ford dealership can easily look up the information based on your VIN.

Attempting to guess the capacity based on general information can lead to overfilling or underfilling, both of which can damage your engine. Always refer to your owner's manual or official Ford resources for accurate information.
