Question about 2003 Jeep Liberty

2 Answers

I'm replacing the timing belt on my Jeep Liberty with a 2.4L engine. The cams on top have the word ''UP'' and an arrow on both. Also, there are large marks on the gears, and smaller marks 180 degrees away. Should the words ''UP'' be facing up, and which marks should I use to align the cams before I replace the belt?

Look for arrows on the head behind the cam gear they should line up with both lines and the word up facing up

To save yourself a TON of time and aggravation, buy the repair manual for your vehicle. The manual will outline the whole process for you and it should cost under $20.

If you mess up ANY part of the install process, the vehicle will not start/run and you will have to tear the engine apart again. This is where the time and aggravation comes in.

The "arrows" on the gears should be pointing at each other. But you also need to have the engine at TDC (Top Dead Center). The manual will outline this and other processes you need to do.

Is there ANY other engine that will fit in a 2002 jeep liberty limited? 3.7L v6... need a whole new engine


3.7L EKG Powertec, engine. SOHC with roller followers,
did you check compression, or just P030x codes???????
and what if its just a stuck valve or collapsed lifter
why not ask for help in diagnosis?
compression bad? on one or more? cylinders, post #
pull the Valve covers, see if there are broken valve springs
or bad cam lobes, or lifter bad? (motion)
if it didnt burn oil , try rebuilt heads.?

ran for 12 years, so what is the mileage>? 300k?
Oil changes, at 5000 ?

the 3.7 may fit...says wiki.
warning, some engine blocks may NOT be same. (filter mounts, engine mounts) check first.
but you can find this at any engine builders web site. (google them)
ive swapped many and engine, even wrong engines.?grin
there are always choices, i always have and had spare cars.
so down time is never an issue for me.
but others yes. (rent a car is one option while fixing another)
1: if the block is bad get a short block.
2: if the heads are bad get yours rebuilt , or exchanged.
3: if you blew the engine to total destruction, pistons hit valves? (rare)
then get a used engine, or buy a rebuilt.
or pull yours and take it to any top machine shop and drop it off.
bingo, fixed and cheap too. no middle man, to rip you.

history.
The 3.7 liter PowerTech V-6 engine is, essentially, the 4.7 V-8 with two fewer cylinders.
then later, morphed to the Pentastar V6. (today's motor)
cast iron block, (lasts long time, easy to bore and rebuild)
no rubberband cam belts, real chain, drive.
2 valves per cyl. making head rebuilds fast and cheaper.
forged pistons, not cheap cast.
MOPAR is not POS.
ask engineer Brian Crothers

I run the 3.8L in my 08 JK.
its a real low tech, push rod motor. (ended in 2011)

id fix mine, if it failed
my guess is it is head failure, , so get the newer
rebuilds with pinned, valve guides and run it.

I need instructions on how to put on a timing belt for a 95 toyota avalon


You have to remove all the brackets holding the top of the engine on the passenger side of the car, alternator, power steering, and A/C belts. Then you can get to the plastic covers that enclose the timing belt. The large bolt holding the harmonic balancer was a hard one for me - had to use a large air impact (fortunately my neighbor has a tire business and had a huge compressor on the back of his truck).

Align the cam sprockets to the top of the engine with the little arrows on the head. Then you will notice the belt is aligned on the crankshaft at the bottom of the engine with the keyway facing slightly to the left (11 o'clock position or so). It will not be straight up. There is a little "o" mark on the crankshaft sprocket which aligns with a mark on the new belt.

Getting these marks exact requires writing down their exact locations before removing the old belt. Don't try it from memory unless you are a trained toyota factory technician. The cam sprockets at the top of the engine are lettered "R" and "L". The new timing belt will have corresponding letters. The timing belt has to be placed on with the letters reversed as they are facing you (as the "R" cam is actually on your left as you face the engine from the passenger side).

There should be an emissions label under the hood (the front of the car) and near that there should be a diagram showing how the belt is routed just buy the correct belt and put it on but be carefull cause the belt has to tensioned correctly or it will fall off.

Need procedures on replacing the timing belt on a 2005 jeep liberty 2.4L engine.


first thing to do is disconnect the battery, then put a socket on the belt tensioner and rotate counter-clockwise to loosen and remove the belt. next locate the timing belt sprocket case (in front of the engine, top middle of engine) remove the screws holding the casing on. when you have it off you should see the 2 sprockets holding the timing belt, be careful to line up the 2 notches on the sprockets ( to do this you must turn the engine crank by hand using a wrench or ratchet) by this time you should see the bottom of the casing that houses the timing belt. remove the lower case and u should see the whole timing belt and set up. hop this helps you out.

Trying to set timing but cant figure out how to set top of timing


here is the entire procedure tart to finish.
Required tools:
13mm open end wrench 10mm shallow and deep socket 8mm socket long flathead screwdriver 17mm deep socket T50 torx socket 1/4", 3/8ths and 1/2" ratchets and extensions E10 inverted torx sockets 6mm Allen wrench 15mm open end wrench 7mm socket 12mm open end wrench 14mm socket 12mm socket 8mm, 9mm and 10mm Allen head sockets 19mm socket pry bar needle nose pliers
If you are doing this because your timing belt broke you will also need to buy a complete cylinder head, head gasket set, and both idler pulleys. ALL DAEWOO MODELS WILL BREAK THE INTAKE AND EXHAUST VALVES WHEN THE TIMING BELT BREAKS.
Start by removing the air cleaner assembly from the throttle body, remove the air filter and housing jack up the vehicle and remove the wheel, remove the plastic shielding in front of the accessory drive belt assembly, remove the accessory drive belt, place a jack with a block of wood on top underneath the engine oil pan remove the front engine mount, remove the crank shaft pulley ( the 4 Allen head bolts only not the 17mm bolt in the center.) remove the metal plate behind the engine mount bracket on the engine, remove the plastic timing belt cover 3 clips on top 2 10mm bolts on bottom. Rotate the engine until the #1 cyl. is at Top Dead Center on the compression stroke or line up the crankshaft timing mark with the mark on the inner timing belt cover ( notch in cover with notch in pulley) on the camshaft pulleys -- ( intake cam line up the line on the pulley with the line on the inner cover)( exhaust cam line up the arrow on the pulley with the arrow on the inner cover) loosen the 13mm bolt in the belt tensioner and using the Allen wrench rotate the tab until there is slack in the belt. Remove the belt. At this time I would recommend you replace the water pump, both plastic idler pulleys as they tend to overheat and lockup, and the belt tensioner. Make sure all your marks are lined up, you may need a helper to hold the Exhaust Cam in place as it tends to move during belt installation. Put the timing belt underneath the crankshaft pulley, install the belt leaving the intake cam for last and NO BELT SLACK on the right side between the crank and the exhaust cam. Once the belt is installed rotate the crankshaft over 2 revolutions and make sure is rotates freely, and your timing marks are aligned perfectly if not the engine will not run properly, tension the belt as needed. Installation is the same as removal.

To clarify, on the DOHC engine, the intake cam gear has a line on it, and the exhaust cam gear has an arrow on it. These should be lined up with the corresponding line and arrow on the VALVE COVER, pointing straight up. I just went through this process over the weekend, and spent quite a bit of time looking for these marking as I had removed the valve cover. Once I found them, it was plain and simple.
In addition, be sure to not over tighten the belt when reinstalling. The tensioner has markings on it for "old" and "new". DO NOT adjust past "new", as the car will sound like a jet engine, and the belt will not last for very long.
One more item that you may as well replace while you are in there is the cam position sensor if you have not already, as there have been issues with them, and the timing housing has to be opened to get to it
