Tai šlandziņai nekur nav jāiet, tā karājas brīvi gaisā. Normāli, ja tur reti izveidojas pa pilienam.

Etot šlang nikuda ne idut, svobodna boltajetsa v vozduhe. No intensivnogo potoka ot tuda ne dolzno bitj.

"NOTE: It is normal for the water pump to weep a
small amount of coolant from the weep hole (black
stain on water pump body). Do not replace the
water pump if this condition exists. Replace the
water pump if a heavy deposit or a steady flow of
green/brown engine coolant is evident on water
pump body from the weep hole (shaft seal failure).
Be sure to perform a thorough analysis before
replacing water pump."
