It appears that the cooling fans do not go on high until the engine temperature go to 105c/221f so I would think your temperature of 93c/199f is below the range when the fans are to go on high.

So does anyone know approximately what temperature does the stock idiot light comes on?

 

Around the time the engine is toast.

 

In my youth I was a grease monkey/gas boy/tire buster at a place that serviced ( among other British cars , Jaguars ) I never thought I would ever hear a Jag called simple but yes , I do agree its getting nearly impossible to for even independent mechanic shops to deal with a lot of cars

who would ever have believed that balancing 3 SUs would ever be fondly remembered
