I have been having problems with my radiator (1979 210 stock) getting very hot from driving only 11-15 miles! Sometimes the coolant actually boils and know the coolant is good because I just changed it. Yesterday I refitted a new motorad thermostat (180 degree), hoping that would fix the problem but so far it hasnt made much of a difference. I have been told it could have something to do with the timing. I do have a new weber 32/36 fitted as well. Would that have anything to do with it? I also live in Phoenix and it's been getting to about 105 degrees F lately.Any ideas?
