Yes, I had cold coolant leaks. I had to tighten all hose clamps. After that all was good.I would be very careful tightening shock bolts. I don't think they get snug like normal bolts because they have to move. Others have broke shocks because of over doing them. Only tighten to torque specs. The number one thing I would do is check all coolant connections and tighten if needed.
