Default Upper rad hose problems - silicone hose?

Most of you already know I've got a VG30i engine, but I have the water inlet from a VG30e because my 30i one broke back in 2012 when I was rebuilding the top end of the motor. I replaced the upper rad hose during that process but it's been leaking around that bleeder hose deal (previous thread about that). I removed the bleeder hose and have tried both the upper rad hose from the VG30i (too long and wrong bends to fit the VG30e inlet) and the VG30e hose (almost fits, but because of the body lift it's got a kink in it).


I need a hose with 1.25" ID on both ends. I was thinking of maybe using a flex hose or a silicone hose. Anyone here know if either one of those would work, or which one would work better of the two?

One thing you could do is go to the parts store and ask if you can take a look at their rack of radiator hoses. As long as you can find one that has the same ID and the correct bend it should work. You'll probably have to cut it to fit though.

If I could get the truck to a parts store to do that i would. Closest one is about a 20 minute drive. I'm not sure if it'll get there without any coolant in it without overheating :/

Although not the most desirable option, you could always use a piece of metal tubing to splice the line to fit properly. Kinda like the one that nissan used on the VG30E

Yeah that metal linking tube for the bleeder hose is what was leaking this time round, so I'd like to use a solid piece if possible.

This. I remember doing just that when I needed a small U-shaped hose to block off the rear heater unit in an older Suburban.


From looking at that photo, you needed a molded hose, or maybe a flexible hose that has the internal wire support so it can handle the bend.

I've been hunting around but I can't find any flex hose that seems to be the right length. I was hoping maybe silicone would work but I don't wanna keep buying hoses without knowing lol.


I'm never going to lift a truck again. It looks really cool but jeez all the problems you get from it, it's just not worth it.

Go buy a fence post or exhaust tube. Cut and extend what you have. Double clamp where each cut end pushes onto the pipe to make up for not having a ridge.
Flex hose can put undue strain on the plastic inlet neck that will eventually crack the tank. you want zero strain there.
