I noticed my temp gauge starting to go past 1/2 to the hot side. Granted these gauges are actually meaningful compared to later gauges and I was in traffic but moving. I've never noticed the temp going as high as it did. Once I got to speed it cooled down. Water level is good but did notice the fan hard to spin. I read where there is a clutch when it's warm the viscous clutch kicks in. Don't know what normal is. Pump is new. Don't know how old the t-stat is.
