Sheared another bolt on the towbar – these really were rusted through, and the the last remaining one just spins in its hole, so had to drill the heads off all the bolts. The bumper and towbar then fell off. Also took out the last rear quarter window (had to cut and pull the plastic roller off). Removed some strips along the floor and in the door area, and removed some weatherstrips and mounting clips.
Noticed that on the day the car first fired there appeared a bright green – antifreeze – puddle of liquid under the car and in the passenger side floor pan so suspect the radiator, to make sure I’ve cut the water hose entering the radiator and reattached where the the hose leaving the radiator goes – the engine. Will examine if any leaks when I start the car again, soon.
