Aluminum Radiator
I know that aluminum radiator has been installed by some members but I just can't get over how much it improved the cooling of my GT. My original radiator was in a very good shape, cleaned and pressure tested. Still at the speed over 110 kph (70 mph), the needle was creeping up toward 3/4 of gauge range. I am now driving with aluminum radiator for a week, at some real hot weather and the needle never went over 1/2 on the gauge.
The aluminum radiator that I installed is originally used on Honda Civic and its size is very close to Opel GT radiator. I had to fabricate radiator brackets and to modify upper radiator hose and that was it! It took me about 3 hours.
Here are some pictures.
