Lightbulb Radiator Washing Tip

I was talking to a very experienced Cat mechanic, he said the mistake most folks make is washing it out and then running the engine.

He says that just brings dust in to stick to the wet surfaces

He suggested letting dry out real well perhaps over nite then using a compressor to blow the dry dirt out a bit more.

Makes sense I think

Their is more filth in the air driving in the rain, dew and fog.
The mistake people make in cleaning their radiator is washing it out from the front forcing dirt and debris into the fins and not from the back.

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.

I suppose the "very experienced Cat mechanic" parks his vehicle every time it rains or the road's wet? Using the engine heat and fan to dry after cleaning can't collect a fraction of the stuff flung up by tires on a wet road. Makes a nice story but I don't see the advantage.
