Radiator clean up

Postby littlebeaver » Mon Aug 27, 2012 10:03 pm



Hey Guy's, I have a question for you....How many of you guys spray the radiator down well when you wash your bike? Is it worth a trip to the car wash for a pressure spray, surely the radiator would function better if it were clean, dirt and bug free....Just asking, I wouldn't get too close with it though but If someone were to keep it back a foot or two it should be fine, I ask your opinion on this....Good idea or bad idea??? :D I wouldn't use a pressure washer on anything else but the tires not the wheels but the tires..

Virtually never. I'll sometimes send a blast of compressed air backward through it (push the nozzle between the fan blades) if there are a lot of bugs and junk in there.

When I wash the bike I spray onto the radiator ...
But not at a very high pressure...just enough to get all the dirt and dust off...
The bugs come off as well, and the stuck ones stay on for a while but eventually come off...
Driving high speed in the rain serves the prupose too 8-)

I wash both my bikes at the car wash when they get very dirty. Including the radiator. The only way to get them really clean. I just don't get close enough to do any damage or force water where it doesn't need to be. I can see where spraying at high pressure could damage the fins of the radiator if you get too close though.

Yeh I'm talking about maybe 3' or so away from it,,,,hey while on the subject of radiators I have a story and I would like to pick your brains on this and see if you guy's have ever heard of anyone doing this .......years ago when I lived in Montgomery Al. I owned a 85 toyota pickup I'd drive up to Clanton [50 miles away] to a flea market every weekend to sell my crafts, I over heated going up but then it would cool off, I found that it was the thermostat faulty...I replaced and fixed the problem part...But while I was at the market I made friends with many country folks and just good ole boys up there and one of them suggested to me for my radiator problem to put some draino in the radiator :shock: and run it like that, he said draino and water and run it for 10 minutes and flush it out well, he said it would clean the crap out of the radiator really well.. :shock: :shock: Well I didn't do it because it sounds too crazy for me to try, I thought it could hurt some gaskets or something...Have you guy's ever heard of such a thing.. Now this old guy worked for GM and Ford and had a bad ass hotrod he made, it was really hard not to take his advice, but I was chicken and didn't..Have you heard of this?

I would think that would be a great radiator cleaner. it's used on pipes(some are copper too ).
I just don't think I could chance it on my baby though (GL1100 ).

Not in a million years would I ever put Drano in a radiator!!!

Drano has a mix of corrosive chemicals, along with shards of aluminum (designed to cut through hair/clogs in drains), which will trash the seals in your water pump in short order. It also contains sodium hydroxide, which is designed to react with (i.e. corrode) the aluminum shards and create pressurized hydrogen, an exothermic reaction that can boil the water solution it is in. But...your engine block is also aluminum, so guess what else the sodium hydroxide will corrode?

Basically it's fine to put in your radiator/engine as long as you intend on scrapping the radiator and engine. :)

Man, I'm glad I didn't take his advice then, he did make it clear to flush it well though, I just could not bring myself to do it, anyone hear of this being done before...?
