Ford 3S7Z-6049-BB Cylinder Head Assembly

To extract the cylinder head, one will require use of a Tone bit since the head bolt needs this type of bit, use of Allen wrench may round the bolt head. Start by removing the negative terminal of the battery and then evacing the cooling system. After that, you should take off the valve covers, the rocker links or arms along with the pushrods, the intake manifold together with the drivebelt. If left cylinder head is being removed then remove the air conditioning compressor with the lines used for refrigerant still connected also the power steering pump and its bracket but without disconnecting the hoses used. When replacing the right cylinder head, the alternator and bracket needs to be taken off. If there is a wiring harness secured to the rear of either the lower or upper cylinder head, (depending on the model) then remove the tape from it to disconnect it. Pull out the spark plugs and exhausts manifolds, the cylinder head bolts should be thrown away and new ones introduced after loosening the nuts gradually. Lever the cylinder head off the engine, using the crow's foot if further aid is required, against the edge of a casting lug. For installation, all the gasket material and clean all the parts with solvent, no oil should be left on the gasket mating surfaces. Tap the threads in the head bolt holes with a tap and look for any signs of coolant, oil or any other foreign substance. Place the new gaskets on the dowel pins on the block, do not use the sealant at this point, and align the FRONT TOP. Take the heads and new head bolts and put them in place to the required torque. You should put silicone sealant on the block and cylinder head mating surfaces and at the same locations put the intake manifold gasket with sealant. Placed the intake manifold on the engine, put all the intake manifold bolts, and tighten this bolt in the right sequence. The rest of the installation is done in a process of removal in a reverse order; start the engine and look for any signs of oil, coolant or vacuum leaks.

Remove all traces of old gasket material from the head and cylinder block mating surfaces, and clean the surfaces with a rag soaked in lacquer thinner or acetone.

It is preferable to keep the front wheels on the ground as much as possible to make working on the top of the engine easier. Once the right-hand engine mount is removed, further support for the engine is needed if the front of the car is raised.

Remove the camshaft(s) and cam followers.

The remainder of the installation is the reverse of the removal steps. Finally, run the engine and check for oil, coolant, and vacuum leaks.

Ensure the locating dowels are in position in the cylinder block and that all cylinder head bolt holes are free from oil. Apply a small dab of RTV sealant at the timing chain end of the engine.

Compress the spring with a valve spring compressor and carefully install the keepers in the stem groove. If necessary, apply a small dab of grease to each keeper to hold it in place. Grease can also help stick each half of the keepers to a screwdriver or similar tool for installation. Slowly release the compressor and ensure the keepers seat properly.

Smear a little grease in the gap and clean it thoroughly after each piston is cleaned.

Refill the cooling system.

Decarbonizing chemicals are caustic and should be used with caution. It is important to follow the instructions on the container.
