Heater cutting out on turns?

Like many before me, when cleaning the cabin temperature intake I broke the termistor. Replaced it with the suggested model and heater started kicking in, maybe just a bit weaker than before. I live in Canada and winters are tough.
Interestingly enough, while the following termistor is suggested: b57540g1103f000, I have also tried B57863S0103F040 https://www.digikey.ca/product-detail/e ... -ND/739899 with similar results.

What I have noticed though, that when I make hard turns (90 degree as at an intersection), the hot air from the cabin blower holes is replaced with cold air for a brief period of time. I am dumbfounded by why a turn would cause such behaviour in heating / blower.

Any ideas?

The settings are: AC off, internal air circulation only. Only middle and bottom holes are activated.
Turn right or left will start mixing in cold air from the outside...
What gives?

And , have you checked the coolant level ?

yep. Nominal. Had a water pump replaced about 6 months ago in summer, coolant was replaced.

Have you checked the coolant level ? How much coolant is in the reservoir TODAY ? I'm not being a smartass , I just want to know .
