Dodge Intrepid 3.5L SOHC Engine Repair Information

Here you can find information regarding the assembly of the Dodge 3.5L SOHC engine. In this guide we willstart from the inside of the engine including thecrankshaft, connecting rods, and piston ring installation and then move outwards all the way to the pulley beltsystem. Along the way correct procedures and torque specswill be given to aid in the assembly of the engine. Feel free to start from the beggining and work your wayoutwards or skip ahead to your current position in the engine for what you may need.

Crankshaft Main Caps Installation

The 3.5L engine block main bearing caps should be inspected for any defects or flaws before installation.Be sure to lubricate the bearing surfaces prior to installation. Once prepared you can place the caps onto the crankshaftand begin tightening the bolts down in a multi stage process. For the inner bolts you can start by torqueing them down to15 ft-lbs and then follow it up with a 90 degree turn by going through each bolt during each step. The outer bolts can betightened down to 20 ft-lbs and then a 90 degree turn. The main bearing side bolts can be installed last and torqued down to 20 ft-lbs. Be sure togo through each bolt during each step and work your way from the inside or middle caps to the outside or outwards bearing caps.Once finished you should be good to continue with the rest of the engine.

Piston and Connecting Rod Installation

To install the pistons and connecting rods you must first install the piston rings into each piston. Be carefulnot to stretch the rings or break them during installation. Make sure to put the correct rings in the correctpositions, this can be determined by looking atthe instructions given with the new rings. Each ring manufacturer is different so be sure to check for yourspecific rings. Once the rings have been installed you can now fit the connecting rod bearings into the end capsand lube them up with oil or lithium grease. The piston can now be lowered into the cylinder, make sure the dotor mark is facing the front of the engine and that you don't scratch the cylinder.Once installed you can match the connecting rod caps with the correct rods and start to torque the connectingrod bolts to 10 ft-lbs and then to 40 ft-lbs followed by an additional 90 degree turn. After all are done rotate the crankto ensure all pistons move smoothly in and out of their cylinders and nothing binds.

Oil Pump Installation

When installing the oil pump be sure to use the proper sealant around the pump base if neccessary to ensure that oil pressuredoesn't drop due to leakage. Both surfaces should be cleaned and preped prior to installing. After preparing the contact surfaces carefullyinstall the oil pump onto the engine and torque down the pump mounting bolts to 20 ft-lbs. Be sure to tighten down the bolts in a cross patternto ensure that even torque is applied to the pump. From here we can install the oil pump cover and torque down its bolts to 8 ft-lbs. The oil pumppickup tube can be installed and torqued down to 20 ft-lbs.

Cylinder Head Installation

The first thing you must do when installing cylinder heads is to ensure both the block and head surfaces arecompletely clean from dust, oil, and any debris. The next thing you must to isto set the camshafts to their correct positions to prevent any valves from hitting pistons during installationand torquing of the head bolts. Much the same you have to set the pistons to their correctlocations, typically this means putting the #1 piston to TDC or Top Dead Center. Once everything is ready youcan install the head gasket onto the engine block by aligning the alignment dowels.Something I usually do is spray down the head gasket with some engine copper spray from permatex which you canfind here, this ensures that any gaps that could be present between the 2 surfaces gets filled with thespray. Italso helps to transfer heat between the 2 metals. With the gasket in place you can set the cylinder head ontothe gasket and block, if needed have someone assist with this process as the head can be heavyand you don't want to scratch anything or drop it! Once the head has been placed you will want to startinstalling the head bolts to make sure it doesn't move. Be sure to buy new head bolts as many manufacturersuse TTY or Torque to Yield head bolts meaning they stretch during torqueing and cannot be used twice. Also makesure to lubricate the bolts in clean engine oil before installing them into the head.Once all the head bolts have been installed and finger tightened you can start the torqueing process, almost allhead bolts have a multi-step process for torqueing. The 3.5L SOHC engine uses two different sizes of cylinder head bolts with a total of11 bolts being installed into the cylinder head. The 8 main bolts located on the sides of the cylinder heads should be torqued down to35 ft-lbs and then 55 ft-lbs followed by an additional 90 degree turn. The 3 small head bolts per each cylinder head can be torqued down to20 ft-lbs. Make sure to not overturn or underturn any bolt as this can cause an unbalance of surface pressure between the gasket and head.

Timing Belt and Camshaft Installation

On the Dodge 3.5 SOHC engine the timing system is ran by the use of a single timing belt. This belt system consists of a sprocket on each camshaft located at the topof each cylinder head followed by a water pump sprocket located in the center of the engine, a tensioner sprocket, and a crankshaft sprocket.When installing new timing belt be sure that the engine is turned so thatthe number 1 cylinder is set to TDC or top dead center. From here simply slide the camshafts into the cylinder heads and install the retaining bolts by tighteningthem down to 20 ft-lbs. With the camshafts installed you can move to installing the cylinder head rocker shafts. The rocker shafts can be torqued down to 22 ft-lbs.From here we can hold the camshafts with a large wrench or tool and install the camshaft timing sprockets and torque them down to85 ft-lbs plus an additional 90 degree turn per bolt. The crankshaft timing sprocket can then be installed onto the crankshaft by aligning the woodruff key with the slot on the sprocket.From here the belt can be set in place by running from the crankshaft to each camshaft sprocket and then loopingdown to the water pump sprocket as shown in the picture. Be sure to align the timing chain marks with the dots on each sprocket to ensure that the timing is set correctly.Next we can install the timing belt tensioner sprocket which will hold the belt tight during operation. The timing belt tensioner bolt can be torqued down to20 ft-lbs. With that installed the timing belt should be tightened. Be sure to double check the timing marks before moving onto the next section.

Timing Cover Installation

The timing cover on the 3.5L is used to cover up the internals of the engine and hold in massive amounts of oil. For this reason I recommend usingsome silicon sealant along with a new gasket during installation. Be sure to clean all of the metal surfaces prior to installation and placing the silicon onto the metal.With everything ready to install be sure to double check your timing and engine internals before placing the cover in place. Another tip is to lube up thecrankshaft seal with some oil so it seats better. If everything is good to go then place the coveronto the engine block and begin to tighten down the bolts hand tight. Once all of the bolts have been set in place be sure to follow your sealants instructions by waiting the recommendedtime. Once ready you can torque down the larger timing cover bolts to 40 ft-lbs and the smaller bolts to 8 ft-lbs by going in a cross pattern.

Oil Pan Installation

Much like the timing cover on the 3.5L the oil pan plays an important role in keeping the engine oil inside theengine. For this reason I recommend using a new gasket as well as some silicone sealantduring installation. Using the same technique as before with the cover you clean the surfaces of both the oilpan and the engine block and then install the new gasket onto the block and then followit up with some silicone sealant. Be sure to follow your sealants instructions to ensure you get the best sealfrom your application. The oil pan larger bolts can be torqued down to 18 ft-lbs and the smaller bolts can be torqued down to 8 ft-lbs by following a cross pattern.Along with the pan is the oil pan drain plug, this gets removed and reinstalled quite frequently and can betorqued down to 20 ft-lbs.

Valve Covers Installation

The valve cover installation is rather simple, there are rubber seals for each bolt hole and a silicone gasketthat prevents oil from leaking out of the engine. It is recommended to replace both the sealsand the gaskets although if they are in good condition you can reuse them. If you do choose to reuse them Iwould use some silicone sealant along with the silicon gasket to ensure it does not leak.The valve cover bolts torque down to 106 in-lbs or about 8 ft-lbs in a criss cross order. Be sure not to missany bolts to avoid having oil leak out onto the exhaust pipes and cause a lot of smoking.

Intake Manifold and Fuel Rail Installation

When installing the intake manifold you want to make sure you have all the surfaces as well as intake holescleaned out before placing the manifold into position. Once cleaned you can then placethe intake manifold gaskets onto the alignment pins. If you want you can also use a little bit of sealant on thegaskets to help ensure there are no leaks. With the gaskets in place you can now putthe manifold down onto the gaskets and begin to install the bolts. The intake manifold larger bolts torque down to 20 ft-lbs while thesmaller bolts can be torqued down to 8 ft-lbs in a cross pattern.The ignition coil assembly can be torque down to 8 ft-lbs and the spark plugs themselves can betorqued down to 13 ft-lbs, be careful not to overtorque these as they can snap and cause big problems.When installing the throttle body make sure that all of the gaskets are in good condition and will hold a seal as you do notwant to be leaking gas fumes around the engine. If everything looks good you can tighten the throttle body bolts down to 8 ft-lbs.

Exhaust Manifold Installation

The exhaust manifold can be installed by cleaning the surface areas on both the head an the manifold itself andthen by using the exhaust manifold gasket and putting it in place. Once the gasket is in itslocation you can put the manifold onto the heads and begin to torque them down to 18 ft-lbs. I always use somecopper spray from permatex on the exhaust manifold gaskets to ensure I do not end up withany exhaust leaks once done. When you go to install the engine into the vehicle or if it is already in thevehicle the torque specs for the exhaust manifold to the exhaust pipes or catalytic converter is 30 ft-lbs.

Water Pump and Thermostat Installation

The water pump on the Dodge 3.5L engine gets tightened down to the engine block on the inside and is ran off of the timing chain.When removing the old water pump be sure that you drain out the coolant prior to removal otherwise the coolant will spill all over.Once drained you can remove the water pump mounting bolts and remove the old pump from the vehicle. From here we can clean up the engine blocksmating surface and prepare the new water pump for installation. Be sure to use a new gasket and some silicon sealant to ensure that no coolantends up leaking and causes further engine damage down the road. Once prepared you can install the pump onto the engine and hand tighten the bolts down.Once all of the bolts have been installed you can then torque down the bolts to 8 ft-lbs. Make sure to follow your sealants instructions as they oftenrequire you to wait an extended amount of time before torqueing down the bolts. Be sure to check out the timing chain section for more information regardinginstalling it.

Front Dress and Pulley belt Installation

Most of what is left on the engine is just place and tighten objects such as the belt pulleys, belt tensioner,throttle body, oil filter neck, crankshaft pulley, and motor mounts. If the items have a gasket and hold eitheroil or coolant inside the engine then feel free to add some sealant along with the gasket. Always be sure toinspect your gaskets and replace them if there is any deteriation or flaws with them. For thebelt system the crankshaft pulley gets tightened down to the crankshaft at 70 ft-lbs.The drive belt tensioner can be tightened to 33 ft-lbs and the idler pulley can be torqued down to 16 ft-lbs. When installing be sure theyboth turn smoothly and if they do not then replace them with new ones as the bearings can go bad. The enginemotor mount can be installed onto the engine block if it hasn't been already, the torques forthe mount to the block is 45 ft-lbs and then when installing the mount to the vehicle or frame it can be torqued to45 ft-lbs. Finally the throttle body can be installed on top of the intake manifoldwith a good gasket and some added sealant using 7 ft-lbs in a criss cross pattern. For installing the belt youcan use a tool to move the tensioner into its springed state and install the belt as shown in thepicture. The generator or alternator can be tightened down to the engine block using 30 ft-lbs of force.The power steering pump can be installed and torqued down to 18 ft-lbs and finally the A/C compressor can be torqued down to15 ft-lbs of force.
