►UPDATE◄ The water pump should be in later today. While between waiting for that and working on a Cherokee, I figured I should begin the process of removing the bench seat. Two torx bolts and eight nuts, what could go wrong? Well all of the bolts but one came loose before I rounded the last bolt on the front inner driver side. Crawled underneath and found the seat stud up right next to the brake lines I believe. Also saw a large new hole in the floor board where a section had apparently recently fell out. Thankfully the passenger side looks clean still from underneath and from what I saw from slightly pulling the carpet back. So that will be tackled after putting the cooling system back together to complete that project before starting the next one.

Thank you for the response Tj1. Keep up the great work!

Awesome work man! If you had to do the floor again, would you buy the c2c pans or try something else? I'm curious as I may been doing that soon.

Sorry for the late reply but it didn't inform me you replied. As for the water pump, I order one for the engine that was listed for a Cherokee because no place state anything about the Comanche. I figured they were the same and made sure it was reverse flow. I think the brand was like flow something. I was thinking of a gates pump but I kept seeing varying reviews. If I made an error with the pump let me know. It still hasn't shipped yet so I could cancel it for a different pump.

New H2O pump. I figured a new pump would be better in the long run compared to a re-manufactured pump.

►Update◄ So the radiator showed up Monday afternoon as I had begun to start work removing the old one. With this being my first radiator removal from a MJ/XJ, the process probably took longer then expected as I had to determine what all had to be removed. Here is how the temperature gauge would be constantly while driving around during the weekend. It got to the point where I had smoke coming from under the hood twice and thankfully I had coolant with me. So down goes the MJ for cooling system replacement. I removed the electric fan and mechanical fan shroud without to much issue and began removing the bolts that secured the formed channel above the radiator. Thought it was connected to the radiator underneath somewhere since it wouldn't come off for some reason. Figured I should lower the light guard on the front to get the grill off for better sight line. Turns out the secondary cooler I read that had to be disconnect where two bolts on top. Had to grind off one of the nuts as the stud in the radiator started to spin. He is a picture of the culprit. After cutting the nut with a grinder, the cover cross member and the radiator were removed with no trouble. I decided to leave the radiator out while I work on removing the water pump since it gave me more room. With help from my dad, we were able to remove the water pump pulley and I started to remove the pumps mounting bolts. That is when I learned the power steering pump had to be unbolted as well. The power steering pump wasn't much trouble after determining which bolts actually had to be removed. Currently still connected, just leaning up out of the way. After that the water pump was no issue to remove. I didn't have to remove the power steering main support bracket, just loosened the center bolts up some to allow it to have play. Cleaning of the old gasket began shortly after. As I was preparing to begin installation of the new pump, I randomly decided to test fit the pulley onto the new pump from AutoZone. To my disappointment, the pulley was rubbing / scraping on two sections of the pump housing. Hoping it was just a defected part I had received, I took a trip back to the store to switch out the pump. The replacement pumps they had ended up having the same issue or a worst scraping problem. Did this at a couple places and ran into similar issues. :fs1: So now the Comanche sits while I continue to wait for parts to show up as the replacement water pump I ordered is out of stock. :wall: That makes two parts out of stock that I order and am waiting on. So the cooling system is on hold and I will take a look at removing the carpet to see what surprises await me on the floor boards. If anyone has any input or questions, please let me know.

►UPDATE◄ Haven't done much work to the Comanche as I have been waiting on parts and working on a 99 Cherokee sport to pass inspection. The Comanche has still been overheating so a new water pump from Autozone will be going in hopefully this afternoon after I get off of work. I have a new stock replacement radiator also coming in that will be put once it arrives. Hopefully that will also be today but with my luck probably not. Pictures to come once works begins.

I planned on keep the visor even before rare I found out it was. It just through me off when I first saw it but I like the look of it on the Comanche.

So just got back from the junkyard and it turns out to not be a factory one since I don't see JEEP on it. I can post a picture if you like but I apologize for the confusion.

Thank you DirtyComanche! I was confused about the visor when I first got the truck because I never knew they could come with one. But I really like and the truck. Heading to a junkyard this morning to see what parts are left on two Comanches they stated they had in my local jeep group.

Yes I'm interested, if it's in good shape and if it's a factory one . Thanks for the help Yeah I can get some pictures for you today and let you know.

So a couple months ago I finally got myself a Comanche and have been researching among this forum about different ideas for upgrades and repair. This will serve has a tracker for the work done, process for any work completed or plan to be completed, as well as most importantly, a place for feed back from others on ComancheClub! I have limited knowledge even though I enjoy working around cars, but I look forward to the enjoyment form learning as I go and from the great insight the members here contain. Please leave any comments or questions that you have! As for the name, I am a nerd among other things and choose an Autobot Transformer. Trailbreaker was from the late eighties but transformed into an old Toyota Helix which is the closest to a Comanche for any Transformer. Anyway that is the enough from me rambling so here are some pictures for what I am starting off with. More pictures will be coming when I can copy the link to insert them. Only initial spots that need work are around the rear fender on top and the drive side floor. I am nervous about pulling the carpet up but I know it needs to be done.

Thank you everyone for the insight and responses. So far so good until the bottom hose from the water pump starting leaking yesterday on my way home from work. Re-tightened it and shall see how that goes.

There is one in a junkyard Comanche near me. I can see what they want for it you are still interested.

Awesome work! Where did you get the headliner from? My Comanche is missing its and been looking for one.

Its all good Ohm. I have been scolded before by my grandfather for over-tightening NPT before so I didn't do it this time. So far so good but will check all the hoses over again today when I get home. Random questions that is sort of related, what threading is the radiator drain plug? I was trying to find a 90 degree to put in there so I can attempt to make less of a mess when draining it. Thank you everyone for your comments and feedback. I greatly appreciate it!

Thank you for that tip Ohm! i also ran new hoses to the heater core because they connected together at a four way butterfly valve system. Will up load a picture later.

Thank you Jeep Driver! Would / should I flush the entire system as well after I put it back together?

Alright, so I was finally able to drain the radiator and remove the Thermostat housing. The hoses that connected to the housing has some corrosion on them so I might just go head and replace them.

That is true. Overlooked that thought. indeed. Look like a cleaning and flushing is in order MeanLemons thank you for the reply also. I shall clean and flush. Afterwards let you know if there is anything else I'm stumped on. Airborne Janitor, I appreciate the insight and the information. I will get a picture once it is off and report back. Thank you for the replies!

Thank you for the information DirtyComanche!

Omega_rugal, Thank you for the replay and do you think flushing the system would be a good idea after changing the thermostat housing? Also, I want to apologize in advance since I am still trying to figure out the notification system.

So I was looking over the engine since I am looking into a random flux in engine temp and notice yellow/orange ooze that looks to be dripping out of the thermostat. Picture below. Anyone ever seen this before or have any idea what could cause this? Thank you for your time and help.

Hello Comanche Club! I got my first Comanche and loving the truck. It's 1991 4.0L Pioneer Long bed with 138,000 miles configured to an AX-4 transmission and, D30/D35 axles. A bunch of my friends laugh everything I get out of it since I am tall guy (6'6") and driving a little truck. Been doing basic work before I start to upgrade and lift her. I am looking forward to all the knowledge I can learn from everyone here.

Awesome truck and your build thread has been giving me great information for when I start work on my MJ. I also was wondering what kind of bed cover you have and how you secured it.
