88AMComanche Posted June 29, 2014 Author Share Posted June 29, 2014 reaso9n Imasking is because I have a new tank on the way & have no idea what hose to buy for the bottom nipple thing that goes out to the water pump Link to comment Share on other sites More sharing options...
Eagle Posted June 29, 2014 Share Posted June 29, 2014 I believe it's a proprietary (factory) hose with one end expanded larger than the hose body. Don't remember for certain. Check NAPA. BTW, on your Jeep that is not an overflow tank. It's a pressurized part of the cooling system. When you get the new tank, do NOT fill it all the way up. It should be filled to the halfway mark when cold. No higher. Link to comment Share on other sites More sharing options...
91Pioneer Posted June 29, 2014 Share Posted June 29, 2014 It's two different sizes on the end, check RockAuto for the sizing. Link to comment Share on other sites More sharing options...
Bobolink Posted June 30, 2014 Share Posted June 30, 2014 RockAuto doesn't have it. It's pretty much a factory item, 52002063, still available for around $15. Link to comment Share on other sites More sharing options...
88AMComanche Posted July 1, 2014 Author Share Posted July 1, 2014 Okay thanx- What happens if its filled full? thats what Ive always done. Now that I'm thinkin about it,it would build lots pf pressure that way. I believe it's a proprietary (factory) hose with one end expanded larger than the hose body. Don't remember for certain.

91Pioneer Posted July 1, 2014 Share Posted July 1, 2014 If you fill it full it will puke coolant out the cap. Ask me how I know LOL I've never filled it full but I did overfill it slightly one time and it let me know by leaking out. You absolutely need to not overfill because liquids don't compress like air does :thumbsup: Link to comment Share on other sites More sharing options...

Well, it's try to build up pressure. But ... as dainternetguy wrote, liquids don't compress. So if the bottle is full and the pressure increases, there's only one thing that can happen -- the cap fails and the pressure vents through it. The owner's manual and the FSM say to fill it halfway. That's why there's a post inside -- it's marked to show you how far to fill it. Link to comment Share on other sites More sharing options...
