Ok, I decided to go ahead and have kwik kar do my flush, too much trouble to dispose of coolant and do it myself. Anyway, I was wondering if its normal for it to take about 3 hours before my radiator cooled down. After the flush, my truck is still running alittle hot, not much. but i want to put a new radiator cap on it, but the lines and reservoir is still real hot. Before I had the flush, it cooled off in about 30 minutes. I tried to take the cap off, but coolant started to run everywhere and I quickly tightened the cap back on. It looks to me like the bottle is really FULL. Is this normal?? Just checking, hoping it would be a quick fix instead of replacing radiator. Dodge ram 2002 3.7l V6. Thnkx in advance.
