Got a 1995 Toyota Tercel. As the temps have dropped, I have started to use the heat again.
The heat comes on, but not nearly as warm as I remember. And now the temp gauge barely nudges - but does seem to nudge - above stone cold.
I checked the coolant today while the engine was cold. The reservoir is empty but the radiator is filled to the brim.
This isn’t the first time this season it has been cold. My best recollection is that, until this week, the heater and the temp gauge had both been working fine.
So, I’m confused! Any good ideas? Good tests to try?
