Filling the cooling system

[newaccorddriver]

i figure i might as well bring this thread back from the dead. anyways, i followed the steps to fill and bleed the coolant system. my issue lies within the fact that whenever the fan turns on, im assuming the thermostat is opened enough to let more coolant back into the engine possibly? well, i let the car idle for well over an hour or so, and every time the fan kicks on, my coolant level drops. i let the fan kick in roughly 10 times, and the coolant level still drops below the filler neck. in between the wait time, the coolant level somewhat rises and slightly pours out the filler neck, not much as im still adding in more then whats coming out.

do i keep on doing this until the level stops dropping? my heater also flows cool air as well. it starts off hot, then cools down

Idle the car until the fan has come on twice. Fill the radiator up to the bottom of the cooling neck and you're done.

i did that already and it was still taking in more coolant and my heater doesnt blow hot for more then a few seconds

You have a leak in the cooling system somewhere.

oil looks normal. exhaust smokes, but its because it is pretty cold here right now.


the motor was fully rebuilt with 0km on it, and the block/head have been magnafluxed and what not. it is unlikely to be cracked anything or blown gaskets so soon.

i retract my previous statement, it was my radiator end tanks that were pretty leaky


found out after i did a pressure test as none of the hoses were wet, then my end tanks decided to gush out at me
