Mopar RL022133AA Cylinder Head

In order to detach the cylinder heads with the camshaft(s) and the exhaust manifold(s) it is necessary to go through several steps. Start with the intake manifold, the timing chains, sprockets as well as the guides. It's safer to jack up the front of the car and support it by stands and then the exhaust piping can be removed from the manifolds. Identify any of the cylinder head related component like coolant fittings, ground straps, cables, hoses, wires and brackets if any and then uninstall it. To remove these bolts, you will use a breaker bar and the correct size of socket; turn the bolts in a 1/4 turn and then reverse the sequence to avoid warping or cracking of the cylinder head. Remove the cylinder head with the camshaft and exhaust manifold installed lifting it gently where you may need to use pry bar. Disconnect all the accessories mounted on the head so as to bring out the cleaning and inspection session effectively. When fitting, the surfaces of the cylinder head and block must be free from any marks such as carbon or old gasket marks, and remove these using a gasket scraper and clean with acetone or lacquer thinner. Inspect the interfacial areas and decide whether a file is enough or a machining process for several damages is necessary. In the head bolt holes chase the threads with a tap and clean them with compressed air. Using a straight edge check each of the cylinder head bolt for stretch and replace as required. Examine the cylinder head for warpage and examine the head gasket, intake manifold as well as the exhaust manifold. Replace any taken out from the head components, align the new cylinder head gasket into the dowels and put the head back without interfering with the gasket. In addition to this when tightening up the M10 head bolts, the chamfers of which should face the bolt heads, clean engine oil should be applied to the threads and hardened washers of the M10 head bolts but on the MB head bolts, thread sealant shoult be applied. Place the bolts back in their respective positions and torque them until just snug with fingers, and then when tightening the flange to head proceed with right and left sequence for torque and rotational angle. Remove, replace and or adjust the timing chain guides, chains, and sprockets sometimes just takes out and reinserts, fill up cooling system and refill the engine oil and filter it. Last, begin checking for oil and coolant leaks with the engine running.

When removing the cylinder heads, it is important to relieving the fuel system pressure and disconnecting the battery. Next, take off the drive belt and drain the cooling system. Take out the PCV and EVAP system components as well as remove cowl. After that, remove intake manifold and exhaust manifolds from cylinder heads. Remove steering pump mounting bolts and move aside pump. Remove valve covers, rocker arms, and push rods.Then slowly loosen head bolts in increments and remove them by hand.Meanwhile use a wooden block or strike a wood block with a hammer.Lift heads off engine by using a block of wood or by striking a wood block with a hammer.Afterwards, place heads on blocks of wood.When installing heads make sure that its mating surface is clean free from old gasket material and dirt.Clean surfaces with brake cleaner after scraping any old gasket material.Use a gasket scraper to scrape any old gasket material off these surfaces before applying brake cleaner on them.Inspect for damage here if necessary.Remember it is important to check thread in head bolt holes as well as cleaning bolt threads accurately.Make sure new gaskets are positioned correctly on dowels in the block.Heads should be carefully placed onto block without disturbing gaskets.Thread engine oil over head bolt threads then put bolts back into their original locations.If you are going to install new head bolts ensure you torque them right otherwise they will not tighten completely.Finally do this procedure but backwards.Add coolant; change oil including filter if installed; start engine to test run for proper operation and leaks.
