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,

WE dont know if its climate change or age related.
Some are lucky some are not.
But its always best to be carefull .

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