We finally were able to put some miles on the coach with the Napa sending unit. I must say it's MUCH better than the OEM unit. Recently, while on the highway and climbing small hills, around 85 degrees ambient temps, the needle would get up to exactly the halfway point, but never above that. Based on the feedback that would be close to 215 degrees. When coasting or flat areas, the needle would sit just below the halfway mark consistently which would put it close to probably 205-210 or so. And, when getting off the highway and driving in traffic it would dip downward to close to the 1/4 mark when moving.
Based on how this is fluctuating, would it be recommended for us to have the radiator flushed or checked? We do still have the OEM brass radiator. Appreciate the feedback on this!
