High Water Temps after switching off

Nikp, I had the same set up on my last rex and when the Apexi got to 83 degrees the guage plumbed in by the rad would bling into life and read exactly 83 too. Then the thermostat opens and closes slightly and the temps always read the same on the two, did on mine anyway! (untill switching off then apexi rises and other one falls).

BTW, maybe traffic thru Bristol is gonna get heavier for a few months while they do the M5 widening, Clevedon to Portishead.   Have you seen all the new digital speed cameras, six of \'em so far!  Reckon they\'re gonna pay for the roadworks!

Cool - 1.9 bar it is! That means boiling point is above 100 degrees c - but not quite sure how much higher!

For pure water, it rises to somewhere just below 120C. However, as Dave says, the effect of the antifreeze is more pronounced.

I actually find there can be a discrepancy between the temp gauge and the apexi. As the rad cools the water the apexi shows its slightly behind the rad gauge in showing the coolant cooling down.
