2004 Ford Ranger - Low Coolant/No Heat

low coolant in radiator, low heat

Add coolant, watch level. If heat comes back, great. If not start suspecting a bad head gasket.

Thank for quick response. Also has a whine you front. Thought it was a belt, could be water pump. Coolant stayed about 3 inches from top after refill. Good heath. Most likely needs a good flush. Picked up truck a few months ago.
Have not made any repairs except for a leaky 4 WD box.
