Yes it will, I have placed in a 2001 4.0 into my 1988 Cherokee. My only difference was no place for the knock sensor "No big deal" and changing the temp sensor into a different water neck housing instead of the engine block. You will have no trouble switching the engine, just use all the outer parts from the 1988. Hope this helps. P.S. 4.0L I6 "Power Tech" - 177 hp @ 4750 rpm, 220 ft lb @ 4000 rpm - used 87-90 4.0L I6 MPI "Power Tech HO" (High Output) - 190 hp @ 4750 rpm, 220 ft lb @ 4,000 rpm - used in 91-95. So you will also be getting some better HP. :)
no. 1986 to 1990 sorry
I would assume it would. I haven't worked with those specific years but everything I've seen with the Cherokee(and jeep in general) is that most years are interchangeable as long as they are same engine size.
possable a fuse is blown
there really is no difference in the engine it will be the computer and electrical connections
The 1988 Jeep Cherokee fuel pump relay switch is located on the firewall in the engine compartment. The switch will be on the drivers side of the firewall.
The engine computer is the voltage regulator.
Yes, but you will need to use the parts off the vehicle you are putting the engine into.
Yes, it is fuel injected.
THAT WOULD BE A yz125u 1988
yes as you will have to change some parts over from engine to engine but yes.
2.0 dohc turbocharged.
your accuater is starting to go its located on the front differential drive safe
A 1988 Jeep Cherokee has one oxygen sensor.
No, different trans's EDit: Depends on what the engine is... if Both Jeeps have a L6 4.0 then yes the Transmission should fit.. if the Grand Cherokee has a V6,V8.. then no..
Engine "blow-by" excessive engine wear - bad piston ring
i would suggest putting a new thermistat in. it only takes about 30 minutes to do and the part is cheap
An AW4 transmission from a 1991 Jeep Cherokee will not fit into a 1988 Jeep Cherokee. The transmissions in the varying years do not appear to be compatible with one another.
I would suspect excessively worn or broken rings.
YES, that would be a TBI / Throttle body fuel injection engine.
YES, They are the same engines. That would be a direct bolt in.
My 1993 Cheeroke with a 4.0 In-line 6 cyl. and 4x4 is 6 quarts, yours should be the same.
Four cylinder would be 1-3-4-2 with a clockwise distributor. Six cylinder would be 1-5-3-6-2-4 with it having a clockwise order as well.
The The fat lady has sung on that engine. Cheaper to get new engine or car than to attempt to repair -which would be unlikely
