Precooler control valve: control line damaged against the bracket. 737-6/7/8/900

When you do inspections under the engine thrust reversers, take a look at the precooler control valve control line, found on the LH side above the engine. The control line can be positioned against the bracket, causing a chafed/damaged line, which results in a precooler valve not closing. So make sure the line is free from the bracket and not damaged. See pictures of a line which is cut half through
