Maintenance/Repairs

So the engine block, the water pump, thermostat, and pcm have been replaced. Works fine except: at high speed engine temperature is good. At low speed or idle it heats up rapidly to just above half-way and stabilizes. Then the low coolant warning like starts to flash and comes on permanently. Driving at high speed reverses the process. The radiator fans are working, and the coolant is in the radiator - it gets hot to touch.
