04 Honda civic, overheating pump was making noise, knew the pump was bad. Installed new pump timeing belt. Put back together and started up first turn over. Ran hot after running and test drive. Top hose was hot bottom was cold. Replaced thermostat. Tried to bleed system, bottom hose got warm but could get not heat in car. Turned heat on fan off still no heat and car over heats after idles for 15 mins. Theres is no bleeder valve I can find. The person driving ran it hot for some times. Dont seem to be intake are head gaskets as no miss are water in oil. Any help. Thanks

Sounds like an air lock in the system, take a heater hose off and back fill the heater core with clean water, re fit hose but do not tighten clamp, run engine and move hose a little so coolant can escape you may knock out the air as well, when you feel both heater hoses warming up tighten all clamps and continue with bleeding the system as normal.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
