Fluctuating heat
I've noticed lately my 07 escape hybrid's heat will cool down when coasting and warm right back up to hot when accelerating.
Coolant level is fine and no odor of antifreeze inside.
290,000 mi.
Any ideas?
Thanks.

Either air in the system or an eroded water pump impeller. Low coolant could cause a lack of coolant flow through the heater core, or a worn impeller could be pumping less than desired.
