Cleaning the radiator shelf

[burner31]

Been in the upper 90's with a heat index of 108-119 here in Oklahoma lately, my car started running a little warm, so I pulled the radiator, turned it upside down and gave it a good flush.
The picture shows what was sitting on the radiator tube shelf, blocking some of the flow, runs a steady 160 on flat ground and 170 going up hill now.

I'm planning on driving to a car show in a few weeks, about 125 miles round trip, don't need overheating problems.

Let's all REMEMBER, flakes & crud, stuck in the top of radiator tubes, IS the most common cause of OVERHEATING! BACKFLUSHING is a must, ONCE OR TWICE A YEAR!
