should the expansion tank be hot?

Hi guys ,
As you may already know ive already put a new head and rad in my 2.5d n reg aft.
So i am constantly checking levels etc.
But I RECENTLY noticed that the expansion tank is hot to the touch. Not boiling .
Is this normal or am i paranoid android.

Yes - it's not actually an expansion tank and has water circulating through it.

thanks franco , just didnt like to take any chances.
Read through the overheating debate (ww3) but couldn't seem to get a definate answer to my question.
Apart from that everything seems to be okay with my new head.
Thanks for your quick response.

As franco says it's a coolant reservoir, not an expansion tank and has (or should have) water circulating through it all the time.

Cheers scanner,
had a hilux surf, so i know about the dreaded jap head problem.
WE dont know if its climate change or age related.
Some are lucky some are not.
But its always best to be carefull .
Thanks for your imput.

If it doesn't warm up you have a circulation/air lock problem so it is definitely a good thing it is getting hot.
