Small job on the Corolla. Took a while before it dawned on me that the temperature guage wasn't indicating proper temperature. I diagnosed the thermostat after looking it over. Never replaced one before but it's a smaller job so I took it on. Now I have great joy watching the temperature guage move up to medium and I know all is well because of something I fixed. Just like when I apply the brakes I know they are mine, too. The simple joys of a weekend mechanic. Didn't even need to use one cuss word on this job, either.
