The camshafts are held down using several bearing caps which need to be in order with the arrows facing the front of To install the timing system on this engine you must start with installing camshafts into the cylinder head and then the camshaft This chain system consists of a sprocket on each of the camshafts along On the Dodge 2.4 DOHC engine the timing system is ran by the use of a timing chain. To now overturn or underturn any bolt as this can cause an unbalance of surface pressure between the gasket and head.ĭodge Avenger 2.4L DOHC Cylinder Head Torque Specs : 25 ft-lbs + 50 ft-lbs + 90° These head bolts should be tightened down to 25 ft-lbs and thenĥ0 ft-lbs followed by an additional 90 degree turn. The 2.4L DOHC engine uses a single size of cylinder head bolts with a total ofġ0 bolts being installed into the cylinder head. Head bolts have a multi-step process for torqueing. Once all the head bolts have been installed and finger tightened you can start the torqueing process, almost all Any hole that does this should be installed with some silicon sealant.Ī little goes a long way in this step and you can check holes by shining a flashlight down them and looking in the water jackets. ![]() On Dodge DOHC engines there is occasionallyīolt holes on the engine block that cross into water passages.

Once everything is ready youĬan install the head gasket onto the engine block by aligning the alignment dowels. Locations, typically this means putting the #1 piston to TDC or Top Dead Center. Much the same you have to set the pistons to their correct To set the camshafts to their correct positions to prevent any valves from hitting pistons during installationĪnd torquing of the head bolts. The first thing you must do when installing cylinder heads is to ensure both the block and head surfaces areĬompletely clean from dust, oil, and any debris. To ensure all pistons move smoothly in and out of their cylinders and nothing binds.ĭodge Avenger 2.4L DOHC Connecting Rod Torque Specs : 15 ft-lbs + 90° Rod bolts to 10 ft-lbs and then to 15 ft-lbs followed by an additional 90 degree turn for each bolt. Once installed you can match the connecting rod caps with the correct rods and start to torque the connecting Or mark is facing the front of the engine and that you don't scratch the cylinder. The piston can now be lowered into the cylinder, make sure the dot Once the rings have been installed you can now fit the connecting rod bearings into the end capsĪnd lube them up with oil or lithium grease. Each ring manufacturer is different so be sure to check for your The instructions given with the new rings. Positions, this can be determined by looking at Make sure to put the correct rings in the correct Not to stretch the rings or break them during installation.
