You guys did an install one one of these assemblies on YouTube.
1993 to 2001 Camero Iroc. It's the same as my 1994 Firebird Formula. I purchases a heater bypass hose and am trying to find out two things. The cost of the hose assembly and the id of the intake and output hoses?
Hope to hear from you soon. Thanks, Wm Ishmael

No I can't Roy. I'm an old guy and still have a flip phone. 1994 Pontiac Firbird Formula 5.7 Ltr with overdrive. The reason I'm asking is for two reasons. The bypass hose I purchased is 3/4" id and 5/8"id on the other side and the hose is shaped like a "U" and if I get them loose and may and have to cut and shorten one hose on the car. I want to know what a replacement assembly would cost and when I do get it apart I want to make sure my straight fittings for hose to hose connection are the right size.
Thanks again

Got it.

That hose is correct. The 3/4 part goes to the water pump and the 5/8 goes to the intake side.

A picture would help a lot. Maybe you could get someone else with a better phone to take a picture.

Try this for now, the assembly is correct at the firewall, but from there it goes down and I can't see that until I get it put on a lift. Thanks again, and I'll try something on that picture.

Those are heater hoses, not bypass hose as you requested.

Yes, you need to get the bolt from the bottom for the mount.

They are predetermined sizes for the hoses and they only go in one place.
