EastTnZ Posted January 11, 2014 Share Posted January 11, 2014 I can't remember off the top of my head but a search led me to it the first try. Oreillys auto parts had it and advance auto or autozone did not carry the gates part numbers if I remember correctly. Quote Link to comment Share on other sites More sharing options...
PLATA Posted January 11, 2014 Author Share Posted January 11, 2014 (edited) There was and old thread that had that info with parts #s , but I can not resurface it . My Z is at her winter dorm and will like to have them on hand and avoid the hassle of taking them off and hunt for similar type at a Napa store. It will be ideal to have a source with a part #.

ktm Posted January 12, 2014 Share Posted January 12, 2014 (edited) I opted for something a little different for the lower radiator hose. I spent countless hours searching for my answer and tried numerous hoses, but finally settled upon something that is, in my opinion, a lot better than a single hose solution. I went with a straight piece of 1.5-in. diameter aluminum pipe that then uses two angled hose pieces, one coming from my Arizona Z-car aluminum radiator (which is setup like a 280z radiator) and the other connecting to the thermostat body.

socorob Posted January 13, 2014 Share Posted January 13, 2014 I picked up all 3 of the hoses listed above. If I get a chance tomorrow I will try to see how they fit. I will post back here as soon as I do. Quote Link to comment Share on other sites More sharing options...

socorob Posted January 13, 2014 Share Posted January 13, 2014 The 22478 radiator hose with champion radiator, Taurus fan and GTO Ls1 works on the lower hose. The 21503 won't fit anywhere on my setup. Will try top later. Quote Link to comment Share on other sites More sharing options...
socorob Posted January 13, 2014 Share Posted January 13, 2014 The issue I'm having with the top hose is either they hit the Taurus fan which is fairly thick, or the intake hose is in the way. I have the steam vent tee so I'm good with combining 2 hoses but can't find 2 that will work together. I bent up a coat hanger and looked thru every hose at autozone and no luck.

PLATA Posted January 13, 2014 Author Share Posted January 13, 2014 (edited) ^^^^ thanks for your input. Here is my upper hose >>>> >>>> my rad looks like this one Edited January 13, 2014 by PLATA Quote Link to comment Share on other sites More sharing options...
socorob Posted January 13, 2014 Share Posted January 13, 2014 The champion radiator I have has the lower hose nipple going straight out, it's not a 90 degree bend like yours, so the hose I used may not work on your lower. Quote Link to comment Share on other sites More sharing options...
280zjake Posted January 13, 2014 Share Posted January 13, 2014 Look in my photobucket to see pics of the hoses installed http://s591.photobucket.com/user/shupaye1/library/280Z%20pics?sort=3&page=1 Quote Link to comment Share on other sites More sharing options...

socorob Posted January 13, 2014 Share Posted January 13, 2014 I found these numbers while searching on here in an old post: Part numbers are as follows. Upper hose, PN 82570, crosses to Dayco 71314, Gates 21588, Goodyear 61394. Lower hose to LS1 T-stat housing, 82825, crosses to Dayco 71380, Gates 21712, and Goodyear 61457. The other half that goes to the Datsun radiator is an original for the Datsun, Gates PN 20776. The two beaded tubes I bought from hrpworld.com and have PN's Z17632 (1.375") and Z17633 (1.5"). The 22625 will probably work for your top one since your air intake goes the other way. My fan and intake get in the way of that one on mine.
