Cooling system upgrade

Postby dragginmini » Mon Mar 20, 2017 9:51 pm

I swear I looked. I have upgraded my cooling system with a aluminum radiator and electric fan. The bottom outlet on the radiator is 1 3/4" and as you can see it's a bit of a close for a lower radiator hose? Any extra advice is greatly appreciated

I bought a very similar radiator from Summit after I did my bodydrop. The lower outlet looks right at my power steering pump. I went to Autozone and bought a hose with a slight bend in it that would redirect it away from the pump.. then I made an adapter piece that I could reduce the hose size from 1.75" to the factory 1". For this I also bought a random hose from Autozone that had a 180 degree bend in it then a slight bend back towards my water pump.. it's hard to explain but I made it work. It basically comes off the outlet, reducer piece, snakes around my power steering hoses, and is directed up to the water pump. None of the hoses are factory. I went to Autozone and pieced together a two hoses, and it works.

Wow that's a sweet radiator. Where did you find it and how much was it? I like the header too, did you build it or buy it?
