Re: Another heat problem 'thread'

Remove both heater hoses at the front of the engine. Use a garden hose to flush one hose then the other back and forth every 20-30 seconds for a few minutes total time.

Old coolant will precipitate silicon particles that like to collect in the heater core due to the lower flow rate or the confined spaces as compared to the rest of the engine.

Consider that the water pump fins are corroded resulting in low flow rate at low rpms.
