I do appreciate the help from all. This is a learning process for me for sure. Looking forward to all the knowledge and willingness to help. Sent from my iPhone using Tapatalk

I have checked around but need to do more research first. It was the initial plan but again have to find the right cluster as far as speedo gear and tach setup and so on. Sent from my iPhone using Tapatalk

I have seen these and tried to figure them out. I would imagine it’s like a scan tool in monitor mode. I would like to invest in one for sure. I would imagine it would be able to monitor everything as I’m not even sure if a PO had the left side dash indicators connected. As I look under the dash I can see the harness and it appears to be connected. Sent from my iPhone using Tapatalk

If I can keep the Renix intake and exhaust I will do that. I do have plans on going through cruisers list and try to improve on the setup. The end goal is to have something reliable and easily maintainable. I try to do all the work myself. The current cluster is the one with the dummy lights. I have bought the 3 gauge kit with temp, oil pressure and volts. I don’t mind wiring them up and hooking them up. Kinda ocd with the wiring and everything in a loom and clean looking. I have my work cut out on this one. But I have a t-stat housing off of a 99 4.0 that has the sensor port. For when I do the conversion. I know the oil sending unit will have to be “T”ed off for both. I was looking last night at the head for the sending unit for the coolant light but couldn’t find anything. Which is probably why the PO hard wired the e fan to come on when the key is on. Tied in to the fuel pump too. Then then the hot wire into the fuse block for constant acc power. Sent from my iPhone using Tapatalk

That’s what I'm thinking. I'm going to go through cruiser list and do a coolant system swap. I’m assuming the biggest upgrade was the HO heads. With the ports being bigger and less restrictive. My biggest thing is having the oil pressure and temp reading accurate. Which is why I’m switching to sensors and running separate gauges. I plan on, from the advice of a buddy, running an unlit propane bottle over vacuum lines to find out general area for high idle issue. Sent from my iPhone using Tapatalk

There are 273+k miles on the Odometer. No telling actual miles on motor. Who knows what a previous owner has done. I contacted the guy that had it last and he claims he had no idea there was a motor swap. Even after claiming to own it for 4 years prior to me buying it. Sent from my iPhone using Tapatalk

No real reason. Trying to figure out a previous owners puzzle. I don’t know much about these 4.0l motors, as I’ve just started learning about them I have a 96 4.0HO and a Renix Intake and manifold. As far as I know the upgrade from the Renix is the head anyways. Once the intake is changed over, I would imagine, would changed the wiring and harness. Just trying to figure out my options to get this Comanche back on the road and reliable. Sent from my iPhone using Tapatalk

Sorry it took so long to reply. Got busy with life. Work and kids starting back to school and everything else going on. Here are pics from the underside. On the intake and exhaust side. Again I have been able to determine it’s a 96 4.0 HO with Renix intake and exhaust. Sent from my iPhone using Tapatalk

I have bought the aftermarket gauges just have to figure out the sensors and locations. It’s on the to do list for sure. I will get pics of the exhaust and intake manifolds tonight when I get home from work. I plan on doing the 97+ cooling system for sure and a few other things. Main goal right now is to figure out what I have and what I can do to get it back on the road. Sent from my iPhone using Tapatalk

Back story. Bought 89 Comanche a year ago it drove fine then started to rev high after running for a while then putting in park and then on restart after a few minutes of being off. Wasn’t a daily driver so not too concerned with it at the time. Working to fix an oil leak, and replacing the RMS and OPG, then still had a leak. Moving to VCG, it isn’t a Renix cover. Checked the cast numbers on the head and it’s an 96-99, then checked the stamp on the block and narrowed it down to a 96. So someone had done a swap at some point. With that they kept the Renix intake and exhaust as well as the closed cooling system. Probably a few other things I’m not aware of yet. So my questions are can I just replace the intake and exhaust manifolds and convert to open cooling. I also want to add the sensors for oil pressure and temp as they are the sending units and lights. But keep the lights too. What else can I do as far as keeping it reliable and parts are readily available while keeping the 4.0.
