I've just replaced a hose for the cooling system and of course flushed it all out and refilled.

Everything seems ok except that now when driving along the temp gauge starts to climb quite high and then drops back to normal.

Also, the overflow tank seems to have filled up to the top.

Now, I'm hoping that this is all just because I've refilled the system and there are a few air pockets that need to work themselves out.

If this sounds like a reasonable theory I'd really like to know.
