Title: 4.0 Jeep Problem ?
Post by: omega3000 on 18 September 2013, 11:53:28
1998 Jeep Cherokee petrol . The bloke has written this but does anyone know of the common problem that causes the Jeep to stop  :-\ Thinking of buying it if it can be sorted .

Jeep will run but stops after 20 minutes. There is a sensor that has gone. I have tried to changed all of them virtually but cannot find fault. I know lots of Jeeps have the same issu

A 4.0 litre cherokee will keep an Omega honest to 60(around 8 secs) but your right about the fuel consumption :y

I used to look after one like the bottom picture,5.7 v8 from memory,that really went but couldn't do corners or stopping very well,very good at drinking unleaded though :-X

Fairly well equipped by looks of it the bottom one, Comfy too i'd imagine.

Two different models ::) bottom one is a Grand Cherokee, and is available with a selection of proper engines...

I had a Grand cherokee Turbo diesel and it was very comfy and dripping with toys,mine was a 2.5 which was a little tardy but later Merc engined versions get along nicely

Pros: Comfort, Lordly driving position, V8 sound.

Cons: Fuel consumption poor, Relatively slow, Ugly, Not much kit, Expensive to buy, Unreliable/Expensive parts ?, Insurance ?, Poor handling, Unless going off road or towing pointless.

Anyone care to add, I can't think of much else at the moment. Unless dirt cheap i wouldn't consider one then again if cheap it will most likely bite you in the behind.  :-\

Hows that then :-\ I thought the "4.0 liter" had the AMC straight 6 (http://en.wikipedia.org/wiki/AMC_straight-6_engine)

Mr Omegaman is a touch confuddled ::)

V8 comes in several sizes from 4.7-6.2 litres in the Grand Cherokee

Regular Cherokee only came with the 4.0 straight six you mention, or a 2.5 four pot diseasel :y

Compared to what?,an Omega?,mine was more hands on than either and had done half the milage,there's good and bad in all things  :y

Cam cover gaskets/breathers 80-120k
Coil packs 80-120k
Scuttle leaks 80-120k
Steering idler 120-150k

Nothing too strenuous there :y

I have the second one in the photos but with the 2.7 Mercedes Turbo Diesel with matching Autobox, pretty quick if you want, just take the seasick pills if on a twisty country road..... :y :y

Used daily for work similar to a 2.2 Mig in fuel costs, comfy and high driving position suit me nicely, leather which I hate is only fault imo. Ignore TB off road comment, the Jeep is very competent off road and coped with floods and snow last winter extremely well.... :y :y

Thanks for comments good and bad  :y Looking for tow vehicle so something with a bit of grunt and capable of towing cars only . It wont be being slung into corners F1 style  ::) Fuel consumption not a problem as it will get LPG ... the car in question has been pulled for what ever reason but there are a few with lpg .. Im sure this one i was watching was a V8 and didnt know they did a straight 6 which seems to be the preferred engine . Whether its good enough to tow is another question but then there is the diesel lump to look at also  :-\
Maybe a different 4x4 would suit better for towing  ;)
