914 subaru water pump over heating Options

[jeepguy06]

hey guys

so I have a ej205 in the 914 and when sitting at lights in traffic it starts to overheat. I watch the temps clime to 208.4 at times if not hotter. I find that revving the car to 3k and keep it for about 30 seconds to get the coolant moving the temps will then drop down to 203. once i start moving and driving the temps drop all the way down to 197.6 I just feel that the water pump is not able to move the water from engine to radiator all the way in the front. has anyone else had issues like this and how did you repair them? add another water pump that's electric?

My car runs at a pretty consistent 165 degrees. Stock water pump. Air pockets are horrible, so make sure it is purged, and then purge it again. I run dual SPal fans that run constantly, not on a temp switch. I do notice that when I am really on it, the temp falls significantly as the water pump flows alot of volume. A stock pump is sufficient.

I use a lower temp thermostat as well so it opens sooner.
