I'm trying to get all the heater hoses set up for my LT1 swap, and I've run into a little confusion.

Looking at shoebox's diagram of the heater hoses on the 94 LT1, I'm a little confused about the tee that connects a heater hose, the throttle body heater and the hose that goes to the water pump. Is this tee a heater control valve or just a standard 3/8" Tee junction? If it's a heater control valve, where does the vacuum line to feed it come from? Thanks.

 

There are no heater control valves on a 4th gen.

 

I didn't think so, thanks!

On the other hose diagram there is the upper hose with a 3/8" (I think?) hose that goes to LH side of the throttle body. Is that integral with the lower hose? Or is there another tee fitting (labeled 14 on the diagram)?

 

If you mean #14 in this diagram, it is all one hose. If you are going to bypass the coolant hoses into the throttle body, just use the 1995 hoses.

 

Thats the one, thanks!
