Hi

I have Honda LX 99 4 Door. Today I started engine to drive and I
noticed that
the thermometer indicator went up and down couple of times (it went up
to about half.) and it became normal and I drove about an hour
without any problmes. This is first time that I noticed it.
I was told that I should check or replace thermostat. I have heard
that after you change something which you should not then more
problmes occur.
I just wonder if anyone has same problem as this or should I check the
thermostat?

Thanks
