Mopar 33007115 Cylinder Head

Disconnect the negative cable from the battery. Drain the coolant from the radiator and the engine block. Remove the air cleaner assembly. Detach the fuel pipe and vacuum advance hose. Remove the rocker arm cover. Remove the rocker arms and pushrods. Unbolt the power steering pump bracket and set the pump aside without disconnecting the hoses. Remove the intake and exhaust manifolds. For air conditioned models, remove the bracket on the cylinder head that supports the idler pulley for the air conditioning compressor drivebelt. Loosen the alternator drivebelt and remove the alternator bracket to-cylinder head mounting bolt. Unplug the wiring and unbolt the air conditioning compressor without disconnecting the refrigerant hoses. Set the compressor aside and remove the upper two bolts from the bracket. For all models, label the spark plug wires and remove the distributor cap with the wires attached to it. Remove the spark plugs. Disconnect the wire from the temperature sending unit and the battery ground cable. Remove the ignition coil and bracket assembly. Remove the heater hose bracket. Remove the 14 cylinder head bolts and lift the head off the engine. Thoroughly clean the gasket mating surfaces, removing all traces of old gasket material. Stuff shop towels into each cylinder so scraped material doesn't fall in. Inspect the head for cracks and warpage. If you are replacing the cylinder head, be sure to transfer all fittings, etc. to the new head. Apply an even coat of Perfect Seal sealing compound to both sides of the replacement head gasket. Position the new head gasket on the engine block with the word TOP facing up. Install the cylinder head on the engine block. Coat the threads of bolt number 11 with Loctite 592 sealant and install the head bolts hand tight. Tighten the cylinder head bolts in sequence, according to the specified torque for each step. Reinstall the remaining components in the reverse order of removal. Add coolant and run the engine, checking for proper operation and coolant and oil leaks.

Remove the rocker arms and pushrods. Remove the intake and exhaust manifolds.Remove the drivebelt(s). Unbolt the power steering pump (if equipped) and set it aside without disconnecting the hoses.On air conditioned models, remove the bolt that secures the air conditioning compressor/alternator bracket to the cylinder head, then unbolt the compressor/alternator bracket from the engine. Set the compressor aside without disconnecting the hoses.Label, then disconnect the wire from the coolant temperature sending unit on the cylinder head. Label the spark plug wires and remove the spark plugs.Remove the ten bolts that secure the cylinder head and lift it off the engine. If the head is stuck to the engine block, it may be necessary to tap it with a soft-face hammer or a block of wood and a hammer to break the seal. Stuff clean shop towels into the cylinders. Thoroughly clean the gasket surfaces removing all traces of gasket material. Run an appropriate sized tap into the bolt holes in the cylinder head and run a die over the bolt threads. Ensure all bolt holes are clean and dry.Inspect the cylinder head for cracks and check it for warpage. 1984 through 1987 four-cylinder engines use different head gaskets than 1988 and later models. The two types of gaskets are NOT interchangeable and require different tightening torques.These engines use stamped steel gaskets. Apply an even coat of a copper coat type gasket sealant to both sides of the new gasket.These engines use a composition gasket. Install it dry (without any sealing compound).Install the new gasket with the word Top on the cylinder head side. Place the cylinder head on the engine.Coat the threads of the stud bolt (no. 8 in the tightening sequence) with Teflon pipe sealant. Install the bolts and tighten them. Tighten them. Install the remaining components in the reverse order of removal.Change the oil and filter.Refill the cooling system and run the engine, checking for leaks and proper operation.

First of all, new and rebuilt cylinder heads are available at dealerships, a more practical option for home mechanics due to the need for specialized tools. You should know that disassembling a cylinder head involves removing various parts, which should be marked and stored separately for reinstallation. The springs on each valve should be compressed to remove the keepers, retainer, spring, and spring seat.
