I got a 2000 Acura TL. This morning my water Temp Gauge stopped working. Little later check engine light came on which I knew was related but had it checked out anyways to be sure which I was right. It was the Coolant Temp Gauge which I replaced. But the gauge was still not working for quite a while until it finally kicked on I'd say a good 30 min to an hour later. Is this something I should be concerned about? Or should I just leave it alone & be happy that it is working again? Thanks.

 

I wouldn't worry about it unless it acts up again.
