With ambient temperatures in the mid-80s in the mornings and the mid-90s during the day, I have been noticing that in stop-and-go traffic with the AC blowing cold on the 1 and 2 settings my SRT's temperature gauge has been running just above the middle mark on the gauge. Do you think this is normal? It usually is so steady right in the middle of the dial, but maybe it has always been like this in higher temperatures. This is my first Summer with the SRT-6. My Limited would have the temp gauge dial stay constantly in the middle all year round I believe.

No mods other than I swapped the Bosch IC Pump for a Johnson.

Additionally, when I installed the Johnson, one of o-ring clamps I bought wasn't tight enough and as a result I lossed coolant. Before I loss too much, I tightened the clamp and topped off the stock coolant with Valvoline Zerex G-05. That was 4 months ago now.

Thanks for your input.

 

It's normal for it to be slightly above the middle in stop and go traffic.

 

Thanks for the response. I figured so, especially given the higher temperatures recently, but wanted to be sure. If anyone else doesn't agree with that assessment, please chime in.

 

Mine's been just above midway for the last five years with no problems. I live in FL where it's hot all the time.

 

Thank you, sir. Makes me feel better.

 

Have you considered running 70%/30% instead of 50/50 coolant mix during the summer? It will run a tad cooler this way.

 

Just above center with the AC on at 104 degrees outside

 

Thanks for the picture! Mine is sitting at that level perhaps even a mm higher, in stop and go traffic with the engine running hot in 85 - 100 degree weather.
