Yea I think the car has a lower temp switch fitted will try a standard one, also the car has the fans on separate loom on constant live unlike original setup which was on ignition.
done 300 miles over weekend and on move fans cut off and rarley come on unless in traffic which is great. We can park the car up and fans can then come on after we have walked away and they stay on for 15mins approximately then.been checking battery after and seems ok .
