MY greatest fear in owning my SSR is having a problem with those top cylinders. This concern and a few recent posts regarding driving my truck in winter leads me to a question. There is probably no definitive evidence either way but I am sure there are opinons about this. Does the temp. affect the life of those cylinders? Today it is ZERO here in Mo. with a wind chill as low as 20 below. Even in my unheated garage my truck is probably sitting at 30 degrees today. In the summer if sitting in the sun at a car show or I have driven it to work on a pretty day the top compartment is well over 100 inside. Do you think the extreme heat or extreme cold either one adversely effects the life of the cylinders? I know they are not the same, but I have tractors that suffer the cold and heat year after year and the cylinders don't seem to be effected from the heat or cold. What say you?
