Hi All,
Worrying symptoms have reared their heads again.
I have 2004 TD5 110 Defender. Yesterday whilst driving up to Mt Glorious from Samford (steep climb, ~10km) my temperature gauge went from normal driving temp (80-85oC) to off the scale >120oC. the gauge is not the standard blue/balck/red normalised gauge but a gradated 0C gauge with the range 60oC to 120oC. there was no reduction in power (limp mode) or other symptoms. I stopped and allowed to cool when possible. the temp reduction was most effective by descending under engine breaking (i.e. circulating coolant, with airflow through the radiator and no combustion occurring).
It may be worth noting that the AC was on full and one of the AC pipes in the engine bay was completely shrouded in ice when stopped to allow it to cool.
This has happened on a couple of occasions before over 6 years of ownership but i have never satisfactory got t the bottom of it.
I have a little black box fitted which include a coolant level alarm.
I am not sure where the temperature gauge gets its readings from.
There does not appear to be coolant in oil or oil in coolant.
I don't like seeing the temperature gauge soar but might it just be a faulty gauge? should I just get a factory normalised one so it doesn't cause panic?
Cheers
John
