1993 lx anti-freeze leak

[johnnyMO]

I just recently bought a 1993 mustang.
The previous owner put in a cobra upper and lower intake manifold which eliminates the EGR plate. They caped off the coolant line with a rubber plug which use to go to the egr plate. The plug dried up and anti-freeze spayed every were.
Is there any other way of plugging it up because It going
to happen again due to pressure and heat. I know I can also weld it shut. Someone told me instaead off plugging it up,I can run the coolant line to the lower intake. Does anyone have any Ideas? I'm a rooky and would appreciate any feed back.
Thanks

on the heater tube that goes to the heater core off the lower intake..put some silicone in the nipple and a vaccuum cap with a hose clamp...then u got to plug off the back of the intake its a 3/8 thread ..then just use 2 vacuum caps on the egr spacer
