The thermostat constantly open and close to moderate the coolant temperature
and when they wear out the engine temperature starts to fluctuate too much. The two primary failure modes for a thermostat are when they’re stuck open or stuck close. The only cure is to replace the thermostat. Jaguar Series 3 XJ6

The series III is very sensitive to cooling system malfunction/lack of maintenance, my grandfather's 86 XJ6 VDP blew a head gasket due to improper maintenance. Coolant should be changed periodically as well as regular replacing of hoses, thermostat, and water pump. These cars run hot from the factory there is not much margin for errir!
Good job Jesse and nice black paint. That 3rd bolt is the hidden one. I put it all back together on my 76 XK6 without the thermostat so I could flush the whole system which I did 6 times. Since the car had a overheating problem because of stuck thermostat, it runs fine now with no problems even without thermostat.
I drank 2 steele reserves yesterday and I feel like shit!!!! God damn I must I always get high!! Pray for me
Again awsome, professional job. Love the Equalizer car too. Those 3s are nice.
