radiator cooling tip

Here's a little tip Ive just heard about ,if your towing or working the engine hard and the water temp goes up disconnect the wind screen washer line from the jets and tie to grill ,a five second squirt into the radiator and watch the temp drop .The steam disperses the heat and cools at the same time .Told to me by a tech after his fan threw a couple of blades on his gxl. Worth remembering I think especially those towing heavy boats etc. in traffic jams around major cities .
