strange cabin heating issue

[cretecrawler]

I have never experienced this issue before in any other vehicle. When turning a corner or circling around or turning in any way with any sort of speed, with the heat on, the heater blows extremely warm air, much warmer than it's blowing when you're just driving down the road. Then just as quickly as it came on hot it goes back to normal as soon as you straighten back out.

I never heard of that either. Checked the coolant level lately?

I'm wondering if you have an air pocket trapped and when turning the G-forces let the bubble move letting more coolant through the heater core briefly.

I agree.

That would certainly be really low coolant. Check see if the overflow has anything in it (if the engine is hot, that be the safest way to check the level).

I had a similar issue with the SV6 van when it was low on coolant. Had to rev it to get any heat when extremely cold. Could also be a partially blocked heater core. Here a good video on how to flush it:
