First time Jeep owner. Picked up an 01, Auto, 4wd, 4.0, with slightly less than 60K on the clock.

The car was flat trailed behind the prior owners Winnebago back and forth between NY/FL, so it has more miles on the drivetrain than the odometer.

Haven't yet picked up the truck, so I haven't been able to absorb the owners/maintenance recommendations yet.

Any advice on things I MUST do at 60K, or on a vehicle that is 13 years old?
Does the 01' 4.0 have a timing belt or chain? If it is a belt what is the recommended replacement interval and is there any upgrade modifications for a beefier belt with a longer replacement interval.

Any words of wisdom or hotlinks to the forums would be appreciated.

this is not a joke... everything!

When a vehicle is new to you... it is very important that you go through it and replace every fluid, filter and tune up item so that you know it has been done!

So lets start..

Oil and filter - the debate is out, and everyone has their opinions. Some people prefer the 15w-40 diesel oils due to high zinc. But zinc is bad for catalytic converts... your choice. A good quality 10w30 and a GOOD filter will do you just fine.. You can research and build your own conclusion based on your findings. I run 10w30 mobile 1 and a m1-301 filter... The filter is over-ized but fits just fine..

transmission fluid drain and fill - You can drain your AW4 transmission pan and add in some fresh new dexron/mercon fluid. I had to do this on my jeep about 4 times to finally get it back to being red. But that all depends on your current transmission fluid quality.

You can also drain and fill your rear differential, and your front (if 4wd)

I run 80w90 gear oil in my rear differential, I do not have a 4wd

Also your transfer case if it is 4wd

My jeep was much older and higher miles.. so i went ahead and flushed out the power steering fluid

I have yet to do this.. but I plan on going around the brakes and doing a good bleed to get some fresh fluid into my lines..

a drain and fill of fresh 50/50 coolant wouldn't hurt either. I just use standard universal fluid. I actually took mine to a lube shop and had them do a fluid transfer so I knew i had fresh 50/50 throughout.. then i took it home and back-flushed my heater core.

Go around all your grease points and put about 2-3 squirts of lube in each of them..

Spark plugs - champion copper seem to be the preferred plug of most I have talked to, gap set at .035

distributor cap (good quality!)

distributor rotor (good quality!)

Ignition coil (personal preference)

Wires (Good quality!)

check and clean your two vents coming off the valve cover.. one goes to the air cleaner, and one goes to the intake manifold. I just purchased new ones and grommets because they were never touched on my jeep. The grommets were hard as a rock

Air filter

i dont believe you have a serviceable fuel filter

Run a can of good injector cleaner through a tank of gas... BG44K is some great stuff..

I would also go up and down the jeep to check for worn stuff... jack it up, check for ball joint and bearing play... check all the tie rods and links.. check the shocks.. check for leaks... take the tires off and check your brakes..

I do all of this and more when i get a used vehicle..

someone will chime in on something i missed

Mopar, napa gold, or wix filters. Do not use Fram!!!

NGK copper core spark plugs

And absolutely use dexron mercon fluid for the transmission.

Do everything else the guy above said.


Welcome to the forum! Glad to have you aboard

I didnt go prepared into the parts store.. I tried to get NGK plugs but the stupid catalog didn't have them listed.. and I didn't have the part number already handy, so I just grabbed some champions...

I prefer NGK but the champions have worked great so far...

Wix 51085 is the factory size filter... the 51515 is the oversized version of it..

my mobile 1 m1-301 is the same as the 51515

factory mopar is MO090

If the radiator fluid looks good, I'd at least change the waterpump, thermostat, and hoses. If the radiator fluid looks muddy or discolored at all, I'd flush the system real good and add a new radiator to the list of replacement parts. Overheating your 01 can cause a head failure. Redoing the entire cooling system is relatively inexpensive..

+1 just ordered all of my stuff for a cooling system replacement for about 230 bucks shipped from rockauto... good insurance!

you probably don't need new coil packs, but if you do(2) are needed, 3 packs per side
Copper plugs from Champion are fine(distributor-less ignition) on our 01s
def good with your cooling system redo as well
what everybody has already alerted you to
Good Luck!
