bighause Posted May 11, 2010 Share Posted May 11, 2010 It's on my 89 4.0 MJ, any idea what it is? I can post a pic if needed. I am going to replace all the hoses and need to know if it is needed or not Link to comment Share on other sites More sharing options...

Pete M Posted May 11, 2010 Share Posted May 11, 2010 my 88 has something in the middle of its lower hose. turns out it's a tube with a temp sensor bung in it. Link to comment Share on other sites More sharing options...
Gjeep Posted May 11, 2010 Share Posted May 11, 2010 MJ's/ XJ's installed with OEM Mopar accessory R12 AC kits were supplied with this. Meaning your truck left the factory w/o air; AC installed by dealer or owner. Link to comment Share on other sites More sharing options...
Geonovast Posted May 11, 2010 Share Posted May 11, 2010 Pic would be nice. I have an 88 XJ with factory air, and there's no box on the lower rad hose. Link to comment Share on other sites More sharing options...
bighause Posted May 12, 2010 Author Share Posted May 12, 2010 It is the small silver piece in the pic that was posted, my truck does not have air and I don't plan to add it. When I replace the lower hose I guess it will eliminate this piece? Link to comment Share on other sites More sharing options...
Pete M Posted May 12, 2010 Share Posted May 12, 2010 are there wires coming out of it? Link to comment Share on other sites More sharing options...
bighause Posted May 12, 2010 Author Share Posted May 12, 2010 No wires, but it looks like you could plug a connector into one side of it. I'll take a pic of it in the morning and post it. Link to comment Share on other sites More sharing options...
jimoshel Posted May 12, 2010 Share Posted May 12, 2010 At one time there were heater's being sold as a substitute for block heaters, They were installed in the lower radiator hose but never really caught on. Link to comment Share on other sites More sharing options...
