2002 Mazda B3000 2 w/d Temp Gauge Question
 

Hello,
I have a B3000, the temperature gauge stays in the middle after turning off the engine, and will return to cold when the engine is restarted the next day. My question is is it normal to stay in the mid position until the truck is started again. I noticed all other gauges return to zero then back up except fuel gauge. The reason I ask is because we had a block heater blow out and dropped all the rad fluid, now we repaired it and need to know normal temp gauge operation.

Thank you.
