Radiator coolant water

[tex439]

Hello
I want to ask you something about my EP91,
I have changed the coolant from green I had in the red from Toyota.
From that moment and every morning when I start my car and go for a short distance listen in my car for 4-5 seconds the coolant passes through to the heater, 4-5 seconds and after it stops.
I have done several times vaporization, but still hear even flow of coolant into the cabin
Any idea plz help me. Thanks

Uninstall your thermostat Valve and Check if the problem is solved or not, Before you do that, try to save your engine Coolant,
its just my .02,

for that reason i change the thermostat before, with original one from toyota and continue the same prob.
You mean take out the thermostat and i try without thermostat? if stop the prob what is mean ?
