The Ranco heater valve/thermostat was an option on all these trucks same as just having a heater was an option. This truck didn't have one and I don't feel the need for one. My 52 I drove for years without one, just a valve on the water pump, on for winter and off in the summer. I do have one if I wanted to use it but for this truck plain and simple is the plan.
I've looked at rebuilding one and it looks pretty straightforward, just be careful bending those tabs.
Tomorrow I've borrowed a steam cleaner and hope to clean the drivetrain and another rear axle.
More updates later in the week,
