Old Kenlowe Thermostat controller. Wish the car still looked like this!
New temperature probe on surface of rad, white staining and rust on rad is evidence of leaking top rad hose where the in-hose probe went. Once fitted engine was run up and temp set by a small adjuster on body of Electronic controller. That was Saturdays job.
Sundays job was to help fit a 4 post lift into a friends barn.
