Cleaning and protecting the flow
I learned this tip from a older fellow back in my trucking days.
I was some place in Eastern Oregon and all of a sudden the sky turned black and as soon as I seen them, I pulled over and cut the engine, but not soon enough.
I filled my radiator with Locus before I was able to shut her down.
I was able to pull enough of them out and limp to a service place that had a pressure washer and we went from the back, (of fan side) out and was able to clean them out. The engine was still warm so the radiator dried pretty fast.
That when the old fellow pointed towards a hardware store and told me to get some wire ties and screen door material to cover my radiator..
Takes a whisk broom to clean the bugs off, If they happen to stick.
I do this on all my cars and trucks now just to keep the normal bugs out of the radiator that you see hitting the window.
To find out if your radiator really needs cleaned our now, wait till dark and put a drop light between the fan and radiator and the look at the front to see if your plugged up.
I probably repeated someone on the forum and maybe you all knew this but I do tend to blabber mouth at times. Hope it helped a few folks anyway.
