Hey guys which one is this? I ordered an upper radiator hose. So I'm assuming its the lower? I mean pretty obvious. But I'd rather not waste another $35 bucks. Thanks....

Its the red arrow....

Radiator Outlet Hose....Part #10256244 for a '94 Z28.

The other larger one [radiator drivers side upper] is the 'radiator inlet hose'.. here are the p/n [but note 93-4 or 95-7 differ]
GM 95-7 p/n 10261148
GM 93-4 p/n 10256242

The smaller [lower] drivers side hose is GM 'engine bypass hose' GM 93-7 p/n 10197675

predator

ok so the one on the driver side with the bypass hose is considered the upper correct because i just want to make sure i ordered the right one i should say the one that goes to TB

Note on these diagrama from shoebox' site the difference between 93-4 and 95-7 configurations:
http://csce.uark.edu/~jgbertr/rb/93-94_hoses.jpg
http://csce.uark.edu/~jgbertr/rb/95-97_hoses.jpg
#16 on both diagrams is the 'bypass hose' [GM 10197675] note that this is a seperate hose, and the same p/n for all [93-7]

#14 is the 'radiator inlet hose'
GM 95-7 p/n 10261148 [note no 'tee' to TB]
GM 93-4 p/n 10256242 [note the 'tee' off the hose that goes to the TB]

If you need the hose that goes to the drivers side TB, well for 93-4 it is the 'tee' hose off the 'radiator inlet hose' [GM 10256242 ]
For 95-7 it is a seperate hose [#5 in the 95-7 diasgram] from the radiator upper psgr side to drivers side TB[GM 'throttle body heater outlet hose' 95-7 p/n 10261149]

I am not going to make a call as to whether one is 'upper' or 'lower'[ since the radiator actually has 5 hoses connected to it..]
The above should help you decide, along with the diagrams..
It also rather clearly shows the difference between 93-4 and 95-7 hoses..

If you use are replacing your hoses i would stay away from water wetter. It makes your hoses break, I found this out the hard way, just check around and youll see im not bs ing. Instead i use this other stuff called towkool. its a little more expensive but it works the same.. or you can go with purple ice. I would stay away from water wetter though.

I tend to doubt that it is available except from GM due to the wierd tee setup..
Where did you order it from?
Are you APO? etc?
I may have a serviceable used one if I can find it..

Or you can buy the Good Year Hi Miler kit [for 95-7] and change to the 'late' [95-7] hose configuration?[I did, I think it a better setup..]This eliminates that 'tee' hose, the 'tt' in the bleeder pipe, and the 'coupling' in the TB pypass mod..

predator

i ordered it from the OPEL dealership here which is the (german) GM they sell camaros transams corvettes so they sell the original parts except emissions are hard to find because germans dont have emissions but it is costing me 47 euro

Assuming then that they use GM p/n's it's the GM 10256242 one that you need..

predator

i am not sure the number because it is 1hr drive so i called them and spoke with them in german and they said they had the part for monday i was just hoping that i told them the right hose upper or lower i told them upper
