Why does my heater only get hot when I accelerate?
It could also be your water pump’s fins may be busted causing not enough coolant to be pumped back into the heater core. Under acceleration the water pump turns quicker. Also, less likely it may be a head gasket leak, pumping air into your cooling system causing an air lock going into the heater core.
