Hey there everyone! I have a 96 cherokee with the 4.0. It had been sitting for the last yr with out being ran/driven due to some legal issues. I am finally getting back around to it and am wondering what some good methods/products to use to freshen everything up after sitting so long. I use it for offroad only and even that is not too often.

 

Charge the battery

Flush the coolant

Change the oil

Change the trans fluid

Change Tcase fluid

Grease anything that can be greased

Fill the gas tank with gas and use some fuel system cleaner/water remover

Wash it

Febreeze the inside




Just throwing some out there...

 

Such as possible cleaner/desludger through the oil,, gas tank, injectors, plugs, wires, diff cases, transfer case, etc, etc...Any help is very welcome.

 

The gas will be your main concern. Use a high-quality fuel system cleaner and fill it up, to get as much fresh gas mixed in as possible. Once you start it and warm it up, change oil and filter. Also, how old is the coolant?

 

Coolant hasn't been changed in at least 2 yrs :-\

 

A flush is in order, then. Of course, check/replace other fluids as needed.

 

Sounds good sir. Any advice on which fluids are best for differentials, tabby and tcase?

 

Assuming you have an automatic:

Differentials: 80w90 API GL-5 gear oil. 75w90 synthetic gives good results. If your Jeep goes swimming a lot I wouldn't recommend it. If you offroad or tow you need 75w140 synthetic. If you have a limited slip differential, be sure to look for fluid that had the additive already, or seek out the LSD friction modifier separately.

Transmission: Dexron III/Mercon ATF. Mostly sold as "D/M Compatible" since the licenses expired. ATF+4 is too thin and gives unpredictable results.

Transfer case: Any ATF or synthetic 5w30 motor oil. Keep it simple and use the same as something else in your Jeep, or use whatever is on hand. Don't fill with gear oil


(I got all excited thinking there was going to be an actual Jeepster in here ugly little things but interesting nonetheless)
