I search everywhere, and its the same answers. Since I have a stock ecu(will get MS2 or Speediuno) that say delete the coolant path to intake manifold. If I recall maybe I misunderstood, but the stock ecu doesn't like that, since it relies on Air Valve for idle.

Will this work ?

when I started fiddling with my 1.6 as NA (in an NA?) I completely removed the 'thermo-valve' from the inlet manifold & deleted the coolant pipework from the thermostat housing to the thermo-valve then also the pipes to the icv & eventually the inlet manifold (by number 1 runner, blocked the steel stub)
also deleted the icv (well, plugged it so it's not operative, still connected electrically to save on throwing 'fault-codes')

this was done as part of a simplification pre-turbo but I've changed direction & am now playing with ITB's

first start (from cold) needed slight throttle untill it had warmed slightly then a stable idle, main benefits were less pipework & less possible leaks :-)

It shouldn't matter, it's common in cars to have coolant flow through the manifold mainly for areas where it gets really cold. But it isn't required by the ECU or anything.

If you mean the lines on the throttle body just connect the coolant lines with one of these to bypass. Not really needed. The ECU won't care one way or the other.
