4g64 Turbo Conversion - change lower rad hose?

[n7k1]

For those of you who turbo'ed your 4g64, did you change your lower rad hose for clearance?

I'm trying to test fit all the OEM components from a GSX and I can't see how I'm supposed to get by the lower rad hose.

I should mention that I did the AWD conversion on it as well

i looked everywhere for a 'swivel neck thermostat housing' but i couldn't find one that fit out cars. ended up cutting a section off an extra upper rad hose off a 4g63 and lower rad hose off my 4g64 and connected them with a 90 degree pvc joint with hose clamps - its not pretty but been holding up great so far but my car is not a daily.

Get that pvc out of there

@pauleyman your absolutely right it wasn't my 1st choice. I recently took it off to check my rad and surprised to say it was in good shape and my car usually runs 185-215F

Your best options might be to custom fabricate a piece, or try AN fittings.

Thanks for the suggestions. I was thinking of trying one of those flexible radiator hoses and see if that would work. I appreciate all the info.

Yeah so what I did is that you can also get a Chevy ls swivel thermostat housing and the gaskets and it fits the same. You just have to use a drill bit to make the holes a little bit wider so the stock bolts fit.

I used that paired with one of the flexible rad hoses from like autozone. It makes it real easy to take off the intake on and off now. Before you kinda have to fight it.

Thanks! I just got a LS swivel housing that looks like it will work perfectly
