DirtyDeeds Posted February 5, 2017 Share Posted February 5, 2017 ok guys, i need a bit of quick info on the cooling system on my 87 MJ. when i got it it had a closed radiator on it and this aluminum coolant reservoir on it with a radiator cap on it. i when i did my 2wd manual to 4x4 auto swap i took the radiator out of my 96 Cherokee that had the cap. i noticed the tank had a few holes in it so i pulled it off to get them welded while i was in there i did a heater core eliminate. lets face it here in south Texas i don't need it! XD not that it worked anyways. My question is can i bypass the reservoir at the thermostat housing and use it just as an over flow tank, or should i run both hoses and keep using the system as is with 2 radiator caps??

Marine1Texas Posted February 6, 2017 Share Posted February 6, 2017 let me know if you want to sell the tank. I need another metal one for my other mj. Link to comment Share on other sites More sharing options...
cruiser54 Posted February 6, 2017 Share Posted February 6, 2017 Get a regular old generic overflow bottle. Let someone else enjoy the aluminum one. Link to comment Share on other sites More sharing options...
DirtyComanche Posted February 7, 2017 Share Posted February 7, 2017 I think you can squeeze a 2.5L overflow bottle in by the airbox... Looked like a clean option, although I have been unable to confirm that it definitely fits with the factory 4L airbox. To me it makes zero sense to have the overflow up at the firewall like that (my MJ has a random bottle there from something, I hate it). Likewise using the 91-96? HO versions doesn't work well because it goes where the coil/ICM is on a Renix. The later one (97+?) is also stupid because it goes up by the blower motor or something and is just goofy by nature, plus you've got things that will be in the way already.

ScottJeep Posted February 10, 2017 Share Posted February 10, 2017 Can positively confirm. The 2.5 overflow fits with the 4.0 airbox. Link to comment Share on other sites More sharing options...
DirtyComanche Posted February 10, 2017 Share Posted February 10, 2017 Can positively confirm. The 2.5 overflow fits with the 4.0 airbox. Nice. Thanks. I'm going to order one up. Link to comment Share on other sites More sharing options...
