phenryiv1 Posted March 4, 2009 Share Posted March 4, 2009 Does the Mopar MO-090 oil filter fit on an 88 with Renix? I have used ot on past 4.0 motors, but never a Renix. I have one (MO-090) in the closet and need to change my oil, but if it does not fit, I need to go grab another filter before draining the motor. I searched, but no results for "MO-090" were found.

BLHTAZ Posted March 4, 2009 Share Posted March 4, 2009 No...the Renix 4.0L uses a metric thread. You can change the adapter to be able to us the 090 though. :thumbsup: Link to comment Share on other sites More sharing options...

Something about a larger filter ,, or something like that..... Link to comment Share on other sites More sharing options...

BLHTAZ Posted March 4, 2009 Share Posted March 4, 2009 On a Renix equiped Jeep, there should be a yellow label on the firewall behind the coolant pressure bottle that gives the metric thread specs of the oil filter. My wife is driving the MJ today so I can't go look at mine right now. The Chrysler part number for the 090 style connector is 53007563AB That is part #18 in this picture. I have been told that it can be interchanged as the threads in the housing are the same on either, it's just the threads on the filter end that are different...BUT...I don't know this for sure...

HOrnbrod Posted March 4, 2009 Share Posted March 4, 2009 Brent is correct; the Renix uses the smaller filter w. M20x1.5 metric threads. Here's a how-to w. part numbers on how to swap to the more common (and larger) SAE3/4x16 threaded filter found on 1991+ models. http://www.jpmagazine.com/howto/5421/index.html Link to comment Share on other sites More sharing options...

mvusse Posted March 4, 2009 Share Posted March 4, 2009 I have a Renix MJ and a HO XJ. Both filters side by side are the exact same dimensions. But the Renix filter uses metric threads and the HO filter is 3/4x16 threads. The HO has a warning sticker about the threads and a Mopar part number for the filter, the Renix firewall has a sticker with a bar code and a bunch of numbers.

I went to the dealer and got a new O-ring set, and was ready to start ripping things apart this week. I was using engine cleaner and was checking out the dimensions down where the filter is located, and it really looks to me like I don't have the space needed to turn the adapter and filter 90* to the rear. It looks like the black cannister in the pictures below will be in the way. Has anyone successfully done the 90* filter adapter swap onto a Renix?

mvusse Posted March 22, 2009 Share Posted March 22, 2009 I just looked closely at both my 87 MJ (Renix) and 94 XJ (Chrysler) side by side. Everything is in the same location, including the charcoal cannister. Looking at the Renix it does not seem like it is going to fit. Looking at the Chrysler I noticed the end where the adapter connects to the block, the block is turned down slightly, maybe 10 degrees or so. Because of this the filter will clear the charcoal cannister with plenty of room. Link to comment Share on other sites More sharing options...
Eagle Posted March 23, 2009 Share Posted March 23, 2009 On the other hand, what's the point of changing a Renix to the newer style filter? The metric filters are readily available everywhere. The two filters are the same size can, so I assume (with no basis for the assumption) that they provide about the same amount of filtration surface area. The only difference is the thread. I can't see any particular reason to make the change. Link to comment Share on other sites More sharing options...

I can't see any particular reason to make the change. I have MO-090s from having my WJ, and my brothers both have XJs (98 and 99), and my father has an 02 WJ. We get the 090s by the dozen. I also need to change my O rings, so if I need to pull it all apart, why not go ahead and do the 90* conversion as well? Link to comment Share on other sites More sharing options...
Oddmodman Posted May 4, 2014 Share Posted May 4, 2014 Old thread, but I wish I had read it before going and getting two WRONG oil filters. Went to Walmart and was like, "4.0s are all the same block; why would there be any difference between HO and Renix..." :doh: . No wonder it was being :wall: Link to comment Share on other sites More sharing options...
87MJTIM Posted May 4, 2014 Share Posted May 4, 2014 Wally World does not carry the Renix oil filters. Their parts don't go back that far. Link to comment Share on other sites More sharing options...
Eagle Posted May 4, 2014 Share Posted May 4, 2014 But Wally World sells Fram filters, and friends don't let friends use Fram oil filters. Advance Auto and Pep Boys both stock the correct, metric oil filter for the 87-90 4.0L in both Purolator and Purolator Premium grades. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted May 4, 2014 Share Posted May 4, 2014 I buy the mopar 5012968a filters for my 88 mj . Thats if you want to stick with mopar filters . Link to comment Share on other sites More sharing options...
Rockfrog Posted May 4, 2014 Share Posted May 4, 2014 Wal-mart up here carries Purolator filters ... no Fram at all. I swapped the filter nipple a while back and use the same filter I run on my 2000 XJ now ... I could never find the metric filters anywhere here. And I peeled the M20 stickum off to be safe if the wife takes it in somewhere ... although that's not exactly security against dumb arses. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted May 4, 2014 Share Posted May 4, 2014 If you end up switching to the newer nipple be sure that you explain to any oil change place or repair shop that you need the newer filter . There just going to "assume" that it's a stock filter for the 88 . Link to comment Share on other sites More sharing options...
Oddmodman Posted May 5, 2014 Share Posted May 5, 2014 I did buy Purolator, just the wrong one. I'll have to go to Carquest for 'em, they're the only ones in town I like. A discount on everything except liquids. Link to comment Share on other sites More sharing options...
mvusse Posted May 5, 2014 Share Posted May 5, 2014 Wally World here started carrying Purolator filters as well, but not the premium Pur-One. They also still have the Fram ones they have carried for a long time now. Link to comment Share on other sites More sharing options...
87MJTIM Posted May 5, 2014 Share Posted May 5, 2014 Wally Worlds near me don't even stock filter sizes for the renix era. I go to PepBoys for them. Link to comment Share on other sites More sharing options...
desertmike Posted May 5, 2014 Share Posted May 5, 2014 Back in 1988 Fram was the only filter I could find that was metric. Been using ever since.. P/N PH3985 for the Renix. Link to comment Share on other sites More sharing options...
