Im just trying to do some basic maintance to my 1990 4x4 4sp AT. The filler tube is attached to the AT pan and I have tried to pry the tube out but it seems to be stuck in there pretty solid, its seems to me that my only option is to remove to upper filler tube bracket and lower the pan and tube...

I installed the new oil sending unit ....and.... Moderator plz insert a drum roll (here) My old sending unit wasnt bad, got the same psi reading from the new one. Actualy I think that the frequent oil changes and additives have washed away all the gum and gunk that was holding the engine...

Thanks SteelHeadz I ordered a sending unit today. I will post the results when I get a chance to put it in. I drive this jeep everyday to work and back and Im trying to restore it as Im using it. I cant recall ever having a oil sending unit act like this before, Im even using 20/50 castrol and a...

Jeep lovers I cant figure this one out.. its a 1990 4x4 4.0 L Cherokee, Even after an oil change the oil pressure gauge says 40+ psi when I first start the motor but after warming up to 185 degrees the oil presure drops to around 20 psi and alittle lower at idel speed. The engine dosnt use oil...

I went ahead and replaced the fuel pressure regulator today (60 bucks),I wont really know till tomorrow morning when I cold start the engine to see if it improved the starting. even tho the engine is a MFI with injectors it stll does not have any back pressure after you kill the engine...

I have a 1990 cherokee 4.0 liter six. Its hard to start but once it gets running it runs fine. I put a fuel pressure gauge on it today and when I turned the key and left it on the gauge read 30 psi and then bleeded down to zero. I started the engine and the fuel pressure stayed at 30 psi, but...

I have a long list of things in a Can that didnt work, like liquid glass.. a friend of mine swore that it was the Cats Meow because it fixed a blown head gasket on a forklift engine. I even read and followed the directions lol and it did not work for me.

When dealing with rusted bolts and nuts the first tool I use is WD-40

I have been doing mechanics on vehicles and other small engines for over 35 years and I know that the best way to repair something is to replace the broken part with a new one, but there is sometimes when I use a "Mechanic in a Can " aka Bars Leak to fix minor radiator and freeze plug leaks, I...

well I got the cap in and it had a pressure releif valve on it.. its a very ****-poor design because I had to use a hose clap to keep it on the recovery tank... The cooling system passed and I am now on to the other list of things to do and replace on a Jeep that has 206.782 miles on it :rolleyes:

its running around 210 degrees even after purging all the air out. I will know more about this cooling system tomorrow when the correct cap comes in but I think this might be a bad design and I will probably convert over to the new system.

My other jeeps have standard radiator caps that are built onto the radiator and a small hose goes to the overflow tank. this design has no radiator cap on the radiator ( see pic ) and apparently uses the recovery tank to hold pressure in it ..lets say 14 psi.... heater core and hoses are clear.

Im wondering if this is the right recovery tank because the correct cap for it looks alot taller in the picture at the parts store and the hood barely closes with the cap I have on it now. and Im guessing the correct cap has somekind of pressure relief valve in it also..pretty sure I have the...

4.0l jeep limited This jeep did not come out with a radiator cap but has some kind of recovery tank system ? the problem I am having is when you go from high engine speed back to idle the water just spews out of the recovery tank ! im not sure if I have the right cap for the recovery tank but...

Thanks for the advise members ... I went with the 100 and all is Groovy now :D

2000 4x4 at Broken Bow Lake OK.. Jan 2011

1990 JEEP CHEROKEE LIMITED 6 CYL 4.0L I just bought this hoopty and it has a bad alternator, the parts store says it could be three different sizes.. 100 amp , 85 amp or a 61 amp. The jeep has power seats, windows and trany control. how can i tell which alternator I need or dose it matter ...

So, apparently the 2.3 reading I got off my Cherokee was really just the Cherokee's evaluation of my IQ. I stopped by a shop and had someone run a diagnostic computer on it so that I could get another code. The codes it sent were: P0141 - P0135 - P0138. The guy also told me that it said that my...

Thanks Bounty Hunter That was as easy as saying "Jihad" lol. I ran the code test and it came back with the number 2.3 in the display. Is there any code reference chart on this web site or does somebody know what 2.3 means ? or what part of the engine it points to.
