The check engine light came on, then took the car to a mechanic for a computer diagnostic.
Result was that I should get my coolant temperature sensor and the thermostat replaced.
The check engine didn't came back on ever since.
Should I still get it fixed now, or wait until the light comes back on?

I cannot find the code on my receipt.
I guess what I am trying to find out is.
Just because the check engine light doesn't come on again does not mean there was not anything wrong with it. Or does it?

It may take a while to duplicate the circumstances that put the light on but it will likely come on again.
