Dodge Caliber 2.0L DOHC Engine Repair Information
Here you can find information regarding the assembly of the Dodge 2.0L DOHC engine. In this guide we will
start from the inside of the engine including the
crankshaft, connecting rods, and piston ring installation and then move outwards all the way to the pulley belt
system. Along the way correct procedures and torque specs
will be given to aid in the assembly of the engine. Feel free to start from the beggining and work your way
outwards or skip ahead to your current position in the engine for what you may need.
Crankshaft Main Caps Installation
The 2.0L 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 crankshaft
and begin tightening the bolts down in a multi stage process. The larger main bearing bolts can be torqued down to 11 ft-lbs and then to
25 ft-lbs followed by an additional 45 degree turn in
a cross pattern starting from the middle of the engine and working outwards.
Be sure to go 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 careful
not to stretch the rings or break them during installation. Make sure to put the correct rings in the correct
positions, this can be determined by looking at
the instructions given with the new rings. Each ring manufacturer is different so be sure to check for your
specific rings. Once the rings have been installed you can now fit the connecting rod bearings into the end caps
and lube them up with oil or lithium grease. The piston can now be lowered into the cylinder, make sure the dot
or 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 connecting
rod bolts to 10 ft-lbs and then to 15 ft-lbs followed by an additional 90 degree turn for each bolt. After all are done rotate the crank
to ensure all pistons move smoothly in and out of their cylinders and nothing binds.
When installing the oil pump be sure to use the proper sealant around the pump base if neccessary to ensure that oil pressure
doesn't drop due to leakage. Both surfaces should be cleaned and preped prior to installing. After preparing the contact surfaces carefully
install the oil pump onto the engine and torque down the pump mounting bolts to 22 ft-lbs plus an additional 90 degree turn. Once installed you
can then install the oil pump drive chain and its corresponding guides and tensioners. These bolts can be torqued down to 8 ft-lbs.
Be sure to tighten down the bolts in a cross pattern
to 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 first thing you must do when installing cylinder heads is to ensure both the block and head surfaces are
completely clean from dust, oil, and any debris. The next thing you must to is
to set the camshafts to their correct positions to prevent any valves from hitting pistons during installation
and torquing of the head bolts. Much the same you have to set the pistons to their correct
locations, typically this means putting the #1 piston to TDC or Top Dead Center. Once everything is ready you
can 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 can
find here, this ensures that any gaps that could be present between the 2 surfaces gets filled with the
spray. It
also helps to transfer heat between the 2 metals. With the gasket in place you can set the cylinder head onto
the gasket and block, if needed have someone assist with this process as the head can be heavy
and you don't want to scratch anything or drop it! Once the head has been set in place you will want to start
installing the head bolts to make sure it doesn't move. Be sure to buy new head bolts as many manufacturers
use TTY or Torque to Yield head bolts meaning they stretch during torqueing and cannot be used twice. Also make
sure to lubricate the bolts in clean engine oil before installing them into the head. On Dodge DOHC engines there is occasionally
bolt holes on the engine block that cross into water passages. Any hole that does this should be installed with some silicon sealant.
A 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.
Once all the head bolts have been installed and finger tightened you can start the torqueing process, almost all
head bolts have a multi-step process for torqueing. The 2.0L DOHC engine uses a single size of cylinder head bolts with a total of
10 bolts being installed into the cylinder head. These head bolts should be tightened down to 25 ft-lbs and then
50 ft-lbs followed by an additional 90 degree turn. Make sure
to now overturn or underturn any bolt as this can cause an unbalance of surface pressure between the gasket and head.
On the Dodge 2.0 DOHC engine the timing system is ran by the use of a timing chain. This chain system consists of a sprocket on each of the camshafts along
with one on the crankshaft. To install the timing system on this engine you must start with installing camshafts into the cylinder head and then the camshaft
sprockets onto the camshafts themselves. The camshafts are held down using several bearing caps which need to be in order with the arrows facing the front of
the engine. The camshaft bearing caps can be torqued down to 8 ft-lbs for the smaller ones and 22 ft-lbs for the larger ones. Once installed you can move to install
the camshaft sprockets. The sprockets phaser bolts get tightened down to 44 ft-lbs. With the camshafts and their phasers installed we can then slide the crankshaft
sprocket onto the crank itself and install the timing chain by aligning the timing marks with the painted links. Once in place you can install the timing chain guides
and timing chain tensioner by torqueing them both down to 8 ft-lbs. Once in release the tensioner and make sure that the chain is tightened up and the marks are
still in their correct positions.

Timing Cover Installation
The timing cover on the 2.0L engine is an important part as it not only protects the timing chain but also keeps engine oil from leaking out
of the engine. Due to this I always recommend using a new gasket along with some silicon sealant to ensure that no oil leaks out of the engine.
When installing the timing cover be sure both surfaces are cleaned properly prior to installing the gasket or silicon. Once ready install the timing
cover and tighten down the smaller cover bolts to 8 ft-lbs and the larger cover bolts to 19 ft-lbs. Be sure to follow your sealants instructions when
tightening as many direct to wait an hour before torqueing down.
Much like the timing cover on the 2.0L the oil pan plays an important role in keeping the engine oil inside the
engine. For this reason I recommend using a new gasket as well as some silicone sealant
during installation. Using the same technique as before with the cover you clean the surfaces of both the oil
pan and the engine block and then install the new gasket onto the block and then follow
it up with some silicone sealant. Be sure to follow your sealants instructions to ensure you get the best seal
from your application. The oil pan bolts can be torqued down to 8 ft-lbs for the smaller bolts and 18 ft-lbs for the larger by following a cross pattern.
Along with the pan is the oil pan drain plug, this gets removed and reinstalled quite frequently and can be
torqued down to 25 ft-lbs.
The valve cover installation is rather simple, there are rubber seals for each bolt hole and a silicone gasket
that prevents oil from leaking out of the engine. It is recommended to replace both the seals
and the gaskets although if they are in good condition you can reuse them. If you do choose to reuse them I
would 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 miss
any bolts to avoid having oil leak out onto the exhaust pipes and cause a lot of smoking.
When installing the intake manifold you want to make sure you have all the surfaces as well as intake holes
cleaned out before placing the manifold into position. Once cleaned you can then place
the intake manifold gaskets onto the alignment pins. If you want you can also use a little bit of sealant on the
gaskets to help ensure there are no leaks. With the gaskets in place you can now put
the manifold down onto the gaskets and begin to install the bolts. The intake manifold bolts torque to 18 ft-lbs
and can be tightened in a cross pattern. The ignition coil assembly can be torque down to 8 ft-lbs and the spark plugs themselves can be
torqued down to 15 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 not
want 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 and
then by using the exhaust manifold gasket and putting it in place. Once the gasket is in its
location you can put the manifold onto the heads and begin to torque them down to 25 ft-lbs. I always use some
copper spray from permatex on the exhaust manifold gaskets to ensure I do not end up with
any exhaust leaks once done. When you go to install the engine into the vehicle or if it is already in the
vehicle the torque specs for the exhaust manifold to the exhaust pipes or catalytic converter is 25 ft-lbs.
The water pump on the Dodge 2.0L engine gets tightened down to the engine block on the serpentine belt side and is ran off of the
timing belt. 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 blocks
mating surface and prepare the new water pump for installation. Be sure to use a new gasket and some silicon sealant to ensure that no coolant
ends 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 18 ft-lbs. Make sure to follow your sealants instructions as they often
require you to wait an extended amount of time before torqueing down the bolts.

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 either
oil or coolant inside the engine then feel free to add some sealant along with the gasket. Always be sure to
inspect your gaskets and replace them if there is any deteriation or flaws with them. For the
belt system the crankshaft pulley gets tightened down to the crankshaft at 155 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 they
both turn smoothly and if they do not then replace them with new ones as the bearings can go bad. The engine
motor mount can be installed onto the engine block if it hasn't been already, the torques for
the mount to the block is 59 ft-lbs and then when installing the mount to the vehicle or frame it can be torqued to
35 ft-lbs. Finally the throttle body can be installed on top of the intake manifold
with a good gasket and some added sealant using 7 ft-lbs in a criss cross pattern. For installing the belt you
can use a tool to move the tensioner into its springed state and install the belt as shown in the
picture. The generator or alternator can be tightened down to the engine block using 17 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 to
15 ft-lbs of force.
