I've never seen this before.
1998 Nissan Frontier. 5 speed manual.
If I'm coasting in gear, with the scangauge showing open loop so I know the fuel injectors are off, the coolant temperature will drop 2 degrees in 10 seconds or less--from say 180F to 178F If I coast long enough, say 40 seconds, the temperature will drop all the way to 173F.
And it'll go all the way back up up to 182F if I'm able to drive for a couple miles without having to slow down or stop.
Other vehicles I've had where I've watched the coolant temp with Scangauge or Ultragauge are far more consistent with the temperature.
Do I have a lazy thermostat?
It seems to warm up quickly enough.
