Overheating 2004 Civic

I have a 2004 Civic ex coupe auto, so maybe 2 weeks ago I noticed my engine was running a lil hot so waited for the engine to cool down checked my coolant. A little low so I decided to add some but I added WAY too much and ever since I've been having problem with my temperature gauge would flucuflue usually just when I'm in idle. I've noticed if I'm going a little slower it'll heat up but then when I give it some gas it'll go down and I've seen it overflowing and bubbling.

The title of your freekin thread says "Overheating 2004 Civic"

Yes head gasket.
All the reasons and answers are in the first post of that thread that was linked.

Re: Overheating 2004 Civic

Sort of amazing people are shocked a 14 year old engine needs a head gasket...

10years from now I bet we will still be getting these posts and the inevitable “Damn, for real”..

Re: Overheating 2004 Civic

It COULD be a radiator cap, radiator, or overflow hose problem causing the system to not pull liquid out of the reservoir as the engine cools down.

But 98% of the time it's a blown head gasket.
Second video in the linked thread offers proof positive on this particular failure. Most other checks people think of just won't find the problem.
