[Kurt in NJ]

I use 2 plunger pumps with the original grease gun ---enough to get in the bearing, but not the radiator too much -----

My radiator was full of grease when I got the car, took it to a radiator shop and had it cleaned, so far no overheating problems no matter how fast, or how hot and it has been 40 years since the rad shop cleaned it, there is some scum in the top tank, but it is nothing like when I got the car
