Radiator /throttle body hoses
 

I would like to eliminate the coolant in my throttle body. However I would also like to eliminate the TEESin the coolant hoses all together. I was told I can use the radiator hose from a 96 corvette for one side. Any solutions for the other???

You really should fill up the profile so we know what car we are talking about besides the fact you reside in the US.

Sorry. It’s a 1993 corvette. 6 speed

On my '93 I just used a reducer to go from the one size hose to the other and put caps on the throttlebody openings to keep dirt and bugs out if I wanted to ever hook it up again.
At one time I thought of adapting lines to have freon from the A/C going into it to keep it cooler.

I also have bypassed the TB coolant line, Live in the south so no need for it.

hoses
 

use 96 top hose, rad to therm. housing and remove tee from heater hose and replace with hosebarb union, cap off throttle body to keep out dirt-bugs. This takes out both tee fittings and both feed and return t.b. hoses, very clean looking after.

could I just run my own new heater hose for the second size? Get like 3’ of house from the parts store and make a new one? No barbed coupling meeddd then?

Two different size hoses. Will need a reducer/coupler to mate the two hoses. Available at a hardware store or auto parts like NAPA.

You could reuse one of the hoses and just get a longer one that you would be replacing. I did use a aluminum coupler rather than a plastic one. Routed and is hidden under the intake tube.

I used new molded hoses when I did complete flush with all new hoses, so used a brass hose barb union for heater hose to heater hose.:yesnod: It was a good time to remove radiator and clean correct way.

Do that, I would. No need to get special years of hose.

Just in case someone should need to do this:
LT1 1994 C4
I did my TB bypass during the engine swap. I figured it was a good moment to replace old radiator hoses after 100 000 miles.
Used 96 molded hoses from Rock Auto

Upper radiator hose: Gates 22463 $13.32
Heater to water pump hose: Gates 19719 $20.79

No tees, no reducers no fitting needed. As clean as it gets
