Thread: Direction of coolant flow in v8

The top hose is the outflow. 107 degrees, is very good,

The attached shows the flow of coolant.

...............and as said 107c is pretty goog.

107 sounds a bit like the upper limit to me, but so long as it doesnt go above the calculated boiling point of the coolant at the systems operating pressure then its all sweet. Id have thought about 98/102 would have been normal

also be wary that the electrical VDO gauges while inherintly accurate themselves do have read errors based on the vehicles electrical system, and how you hook them up.

The mechanical bulb type ones I like to calibrate with a pot of boiling water prior to installation. Ive never had one out by more than a degree or 2 but its nice to know

Whilst not LR, for the record, the Falcon 6 cylinder runs at 118c at half guage on a moderate day.

My XR6 regulary reached 128-130c and was well within design perameters.

With the stat on the D1 set at 88 Deg C, I would have thought that normal op temp would be over 110 Deg C in my view.

..................but I'll check - I have a few high quality (+/- 0.05 Deg C) thermistors, and will let you know.

Fantastic. Thanks for the quick replies. I was a little concerned after spotting a little coolant which had come out via the expansion tank. Thanks again

Just checked using two channels on a Grant Squirrel data logger, using thermistors - and it is reading 105.2 Deg C on both - the ambient was recorded at 27.4 Deg C

Mine is a D2 - but there's very little difference with the D1

I'll stand corrected I was going off of my old 3.9 disco, used to hover the 100 mark at idle and work up to about 115 at full steam full loads. the panic light used to come on at about 125-130ish from memory.
