My engine temp it really low when I am cruising on the highway. The needle sits just above the blue mark. It is in the middle when I am sitting in traffic but other than that it hangs out at the bottom. Is this normal? Is it good/bad?

My 85 c900t runs in the middle as well. I dont know if I should be worried about this or not. Does anyone have any input? Is this Viggen specific, I just dont think this is normal? I was thinking the sensor could be going but like I said the needle is in the middle while sitting in traffic.

I think its a bad coolant thermostat. my 97 has started to do the same thing except not as bad as hangin in the blue. it used to run in the middle of the guage year round, highway or city. low coolant temp is not good for fuel economy, probably not good for engine wear either.
