After an hour and half's motorway run this afternoon covering a spirited 75 miles as a test, the temperature showing on the dash was around 75, via the climatronic diagnostic (Channel 45) it never managed to get over 65!
At this stage my usual response would be thermostat stuck open, but here's where the plot thickens, the top radiator hose is red hot, bottom radiator hose is stone cold, to me this indicates the thermostat hasn't opened at all and perhaps my new (Febi) CTS is reporting the wrong temperature?
Am I getting my wires crossed or barking up the wrong tree here?
Thanks in advance for any wisdom/musings or advice on this chaps
