Running temp & expansion chamber upgrade?
Discussion
I noticed that my bonnet underside has a bit of a dry wet patch (does that make sense). I assume my car has spat a bit of coolant out at some point recently. The coolant level is where it always has been (around halfway up the side outlet 2/3 way up).
I'm wondering if the expansion chamber upgrade mentioned before on here might be needed. Can I ask you guys to report in on the coolant temp at this time of year (on a steady motorway cruise mine runs between 89 and 92deg).
The car was used last summer in extreme (ish) heat in Italy with much trashing around mountains and sitting in traffic jams - no problems whatsoever.

Thanks.

Hello.. I have recently had the expansion chamber upgrade and it does seem to run at about 5deg cooler. Mine has never gone over 90deg even when sitting in traffic and usually sits at about 80 on the motorway. Obviusly now the weather is getting warmer - it might change.. have a 500 mile journey planned this weekend.. 
.. will let you know if it changes..
.. will let you know if it changes..After a good blast at the weekend mine hit 115c 
but as there is no loss of steam or coolant from the expansion tank I presume its a sensor problem (getting it looked at at the weekend).
I have the 2nd tank fitted and the water normally runs around 89-95c.
Thought the 2nd tank was only needed on early models where this was a common problem (original tank to small)?

Just had this mod fitted last friday. Im now on abround 90 for steady stuff and maybe 95 for spirited driving and 90 again for traffic. Thats about -5 on the premodded system. Mine is Jan 2003.
I also have that dry spot above the smaller header tank and assumed it was just where the cap had vented previously and nothing really to worry about.

You may remember I've had problems with mine...
ended up being a couple of things - initially it was an air lock (which is easily rectified), but more recently I had an invisible leak from somewhere...
RADWELD has cured it temporarily but I'll have to get it sorted at the next service...
ANYWAY, coming back to the origonal question..... Before I got rid of the air-lock it was running high 90's, low 100's - then having bled the system, it now runs in the low 90's.. Havent managed to go on a really long drive on a hot day yet, but I'll let you know how I get on when I do!!

hello.. yes I paid about £300 for it to be done.. you could argue it did not need doing as it never over heated.. but I just like spending money !!
