I flushed my cooling system and replaced my thermostat last night because my heater was only blowing cold air. Now the heat works, but my car runs hot. It runs around 180 on the highway and it gets up to about 225 when idling for a few minutes. This is with 50 degree weather outside. The waterpump is only a few months old. After flushing I filled the radiator with 50/50 Dexcool & water. Any feedback or suggestions are appreciated. Thanks.

I'm thinking that maybe I should try another flush. Last time I used the Preston Flush (little yellow bottle) and followed the instructions where you drain the radiator, fill with water and flush kit liquid, run engine for 10 minutes, drain again and fill with water, run engine for 10 minutes, drain again and fill w/ regular coolant and water. I am thinking that the actual hardware flush kit that is inserted into the heater hose and used with a garden hose to back flush may work better. Any ideas?
