jlangv2 Posted February 12, 2018 Share Posted February 12, 2018 (edited) When i was looking up which hoses to use for LS1 to Champion radiators I couldn't find a definite answer so I figured I'd show how I did mine. Hopefully this can help a few people out. Both purchased from O'reilly's and they had them in stock. The hose end that attatches to the thermostat housing is stubborn so you will probably want to use soapy water to make it a little easier. Upper hose PN:22625 Lower hose PN:22478 Sorry for the out of order photos. Every time I uploaded them it would put them in whatever order it wanted.

MECH-E Posted February 19, 2018 Share Posted February 19, 2018 (edited) Nice setup. I personally planned on running one of those thermostat housings from jegs that is a straight input to the water pump from the radiator. That way, you dont have to deal with the weird angle of the stock water pump inlet and they are the same diameter. Jegs Part # : 53270K http://www.jegs.com/i/JEGS-Performance-Products/555/53270K/10002/-1 But hey, nice to know the parts needed to use the stock neck. While I'm here, are you using the stock steam port tubing and if so where are you planning to plumb it in?

socorob Posted February 26, 2018 Share Posted February 26, 2018 (edited) I used 22478 for the lower and 21588 for the upper with a steam vent. Edited March 6, 2018 by socorob added steam vent iinfo Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted March 1, 2018 Share Posted March 1, 2018 Just don’t forget your steam vent. I tapped my water pump. Jim Quote Link to comment Share on other sites More sharing options...
