Coolant leak throttle body have not fixed yet why does it leak

Throttle body leaked coolant, so I bypassed it by pulling off those little hoses and joining them together with copper tubing and hose clamps. This heater is not necessary and is overkill, 'cos even -25 F below zero won't freeze a throttle. I've driven cars and trucks in winter for 30 years and never seen a frozen throttle.
