Quick question

[andydw]

Ever since I've had my Cerb (a speed 6) the fans have switched off with the ignition. A while back the car overheated whilst sat in my drive after a run and blew a hose off. Thats all been corrected now but I noticed yesterday that the temp gauge went up after switching off and I am fearful of a repeat. In every other car I've owned with electric fans they stay on after the engine. Should a cerb do the same ie do I have a fault?

I belive that's heat soak.
The pump is driven by the engine (on the V8) so even if the fans stayed on it wouldn't really help as there would be no coolant flowing.
I used to just wait until the fans went off before cutting the engine.

Hmmm thanks. At tickover the fans cut in and out with the temp moving between an indicated 100 and 105. I just assumed the gauge was over-reading (and it may have been) until the issue on the driveway. Yesterday after switching off the gauge rose to 110 and then hit the stop. No coolant loss though, maybe I am over concerned because of what happened before. I'd be happier if it was runnng a little cooler, I am nervous about taking it out if there may be heavy traffic on part of the journey.

Best thing to do is, download the cerb software and see what's its really doing.

Mine goes well over 110 when it's sitting in traffic in London but its the dial over reading, confirmed by the software.

You can get Joolz to mod the firmaware on your ecu eeprom so the fans cut in a little earlier.
