Tracy - I suppose the new pump could be weak. I just changed the water pump on a 3rd generation Accord and noticed quite a difference in the shape/design of the impellor blades. I've read elsewhere that this can affect coolant flow.

I replaced with a dealer item; the blade design on this item looked as though it could provide better flow.

I wonder if perhaps your new pump doesn't flow as well as it should?

My 2 cents.
