ur old TB had this ancient coolant driven waxstat fast idle cam mechanism,
which tends to seize open with age and which I always advise ppl to remove via here https://www.micra.org.uk/threads/pollymobiles-rebuild.35251/page-19#post-446256
the modern IACV at the front also does the same job.

on the newer facelift coilpack TB, nissan prob leant bout the faulty waxstat and removed it, leaving the IACV (moved to the rear) to do all the idle control.

so to answer ur Q, the old TB coolant lines can be bypassed or simply plugged up cos it runs parallel to the coolant return route.
