What is interchangeable?

[Joe Dirt]

My rig is an 87-4.0, 5 speed. I have a 96 cherokee 4.0 H.O, 5 speed. I'm curious on what motor parts will work on my renix. Thermostat housing? Oil filter housing? I want to swap transmissions but i believe pete m has the swap info for that. I really need to get moving on my rig b4 she dyes on me.... Thanks for your time and any info will be appreciated 👍

Is your engine bad? 

Oil filter housing will work but no point in changing it that I see. 

Thermostat housing will fit but it has a sensor in it you won't be using.

Someone put my temp sensor in the radiator. The 1 in block is broke. Seems like my oil filter housing is leaking and the renix is vertical n the H.O is horizontal witch i like just personal preference just a thought that all the oil won't drain back... I gotta pull the thermostat housing cause my truck doesn't get hot. Idk if its stuck open or someone pulled it out. Truck is a basket case but I'm chipping away at it lil by lil

Oil won't drain back if you use a quality oil filter. 

If you wanna use the common later oil filter, do this. 

 

CRUISER'S MOSTLY RENIX TIPS

RENIX OIL FILTER TO SAE FILTER

JANUARY 3, 2016 CRUISER54 9 COMMENTS EDIT

Tired of having a poor selection of oil filters for your Renix Jeep? Limited availabilty a pain for you? 20mm threads? We don’t need mumblemeter threads on our oil filters.

Here’s a simple mod that allows you to use the very popular SAE threaded oil filters which are more readily available. The old standard 3/4″ SAE thread.

You can purchase a new oil filter nipple from the dealer for under $10 and never be bothered again. Part number 53007563AB. It’s the one on the left. 

Or, grab one off a 91 and later XJ at the junkyard. Be forewarned though. You need a 7/8 wrench to remove a Renix nipple, but a 15/16 wrench for the later style.

And just in case you need to replace your oil filter adapter o-rings, here’s a handy guide.
