How to Remove a Head From an F 250

The Ford "F" series of full-size pickups use the model number to indicate the rated carrying capacity of the vehicle. For example, an F-250 has a payload capacity of about 2500 pounds, and newer models can carry more than this. The standard engine options for the F-250 include 5.4-liter and 6.8-liter gasoline engines. These engines have two cylinder heads, each covering half of the cylinders. The procedure for removing the cylinder heads is generally the same for all F-250 trucks made since 2001 with gasoline engines.

Instructions

1

Remove the air conditioner from the vehicle to access the cylinder heads on top of the engine block. This generally requires a professional mechanic with special equipment to avoid releasing rigerant gas into the atmosphere.

2

Disconnect the cable from the negative battery terminal with a socket wrench to ensure the engine does not start accidentally. Remove the covers for the cylinder heads.

3

Remove the intake manifold from the engine block with a socket wrench. Disconnect the timing chains from their sprockets. Remove the exhaust manifolds from the engine.

4

Disconnect the two retaining bolts for the heater hose with a socket wrench. Squeeze the clamp together, and slide it down the hose to release the hose. Detach the heater hose from the engine block. Remove all additional electrical connectors and hoses needed to access the cylinder heads in your F250.

5

Remove the mounting bolts for the cylinder heads with a socket wrench, and lift the cylinder heads from the engine block. Remove and discard the cylinder head gasket from the engine block. Clean all traces of the gasket from the engine block with a gasket scraper.
