One project I was asked to look into was temperature monitoring on a Triumph Stag. The original V8 didn’t have a good reputation when it came to overheating, resulting in folk throwing it out & installing the Rover V8. These days with the focus on originality a Stag makes stronger money with the original & there are companies who have re-evaluated the cooling system, designed a more efficient radiator, twiddled here & there’s been great advances.
To assess before & after performance I sorted temperature monitoring in the send & return circuit on the radiator, water jacket etc & override switching on the retro fitted electric fan.
As I’ve mentioned on a number of occasions my trusty f acted as test bed for these items, thus I can override both fans, monitor when the fans kick in, see what the radiator circuit is up to (which with the radiator circuit we have is a useful adjunct), as well as check the water jacket temperature.
This last is not a convenient read out to check as it is still in the test rig in the boot!
