I found these today while looking for some of the OEM green hoses.. SAMCO SILICONE COOLANT HOSE KIT CHEVROLET IMPALA LT1 | eBay
I looked up SAMCO and they seem to make pretty damn good stuff. I just put all new hoses on my car, and Ill be honest, only a few of them fit right (ACDelco...). I have long wondered about getting the green hoses but the thing with those is that they dont get rid of the plastic fittings.. Which I have already had an experience with, not bad, but not good either. These samcos are made correctly and there are no plastic connections on them! I see there is not a pressure restrictor, but it might even be 'built-in' given the way they make silicone hoses. I kind of want to sell the hoses I just installed and get these to just be done with the rubber ones, not that there is really anything wrong with them though.. I will be moving back to vegas soon, so heat is going to become a BIG factor for my car.
Let me know what you guys think!
If somehow I can get a set of factory green hoses for cheap enough, I would probably just go that route, but if im going to fork over a 100 bucks for those, I would rather get these.
X2 on the Flow Restrictor....I would and have kept it in my setup.
Do your research on the Samco's here on the forum. I seem to remember something about them "seeping" over time but cant confirm if I'm remembering that correctly but there was some issue. As you said, you wont need the Plastic Tee with these since that section is molded into the hose itself.
If you stick with a stock style hose over the Samco's, you do have options to get rid of the Plastic tee. Myself and others have made one out of metal, here is how I made mine up when switching over to the 9C1 (Green) Silicon hoses.....
Over time I did also try the Good Year "Hi-miler" hoses but was very disappointed how they quickly faded and just did not look good. I later decided to switch over to the Green Hoses and like them for a couple of reasons. They look cool and are unique from most hoses you see. The other thing is they are Genuine GM hoses and I think that is pretty cool.
As far as removing the metal crimps on those stock hoses to replace the fittings, it's very easy to do. Just cut them off with a Dremel or cutting tool being careful not to cut into the hoses.
The process is described pretty well in the above link. If you hunt around and search or get lucky, you could pickup a set of 9C1 Hoses pretty cheap. Last year I found a 9C1 car at the local yard that someone was smart enough to already grab the 5/8" Spindles and Lower Control arms.....Damn! But I did notice a Grimey, Oil Covered set of Green hoses under the hood. Snagged them up for $20 and they cleaned up real nice to keep for a spare set. Hard to believe but after 20 years, these hoses are still solid and have no soft spots or spongy feel.
The clamps used on these normally are referred to as "lined" clamps due to the internal liner that protects the hoses from getting chewed up on the outside and are Stainless. So it's really a cosmetic thing to protect the outside of the hose but you could use standard clamps without issue. I picked up a set from McMaster-Carr for my use.
EDIT - Here is Pic of the old Goodyear Hoses, ehhhh...
and now the 9C1 hoses....much better IMHO
