coolant in the air intake

[STEVEN XU]

About 250ml of coolant was found in the air plastic intake when I removed the air intake assembly. I don't have any idea how the coolant entering the air intake. Any suggestion?

Heater core leak. The heater works because of hot coolant heating the air.

Did you mean engine air intake or ventilation?

I have some recollection coolant is routed around the throttle body to heat it, it could be that you have a leak there. This is a bot of a guess, sorry.
