I'm glad you got it taken care of. You know, if you would have asked me if I thought the water pump was bad, I would have said no. There is only one heater core, so if one side was hot, the other should have been as well.
Regardless, it's fixed and that's all that matters. Please feel free to come back anytime.
Take care,
Joe
