capping off throttle body coolant lines? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

my throttle body for ca18det has two small coolant lines running to it, i already capped off the sources with coolant caps and covered nipples on tbody with vacuum caps, car will be running fri or sat, im just curious why they were there and what will be the side effects. having coolant run through and heat the tbody seems like a reverse intercooler and like its there for emissions/fuel mileage anyway, maybe cold starts too.

It's only there for emissions. There's no side effects from removing them

Cold starting, and to keep the TB from icing in colder climates.
