So I had Lucy the Tank out for a test drive today and all is well. Granted its not 30C degrees outside uphill towing a trailer at 15 miles an hour, so really only time and the coming summer will tell.
But all in all, this car is now 74 years old. Original Motor/transmission/diff/steering/wiring/6v system. Since I got the car in late 2016 I cleaned everything up, rebuilt the suspension, added electronic ignition, a new watepump, a stand alone 12v system to run the AC, modern radio. An extra bypass oil filter, disc brakes, a tow bar ... and a few different attempts at the cooling system. And the car just keeps going.
All I need to do before our cross Canada trip is an oil change and new filters. You cant ask for more than that!
