External Flushing Radiator Fins 8V92

[orbitalsolutions]

Hello, Curt.

I do this often, about every 3000 miles. The best, and in my
opinion only way to do it, is with a HOT water pressure washer.

The same road film, grease, fuel-oil that sticks to your windows,
and everything else, will cover your radiator fins and become a
magnet for dust. The hot water will bow out the grease behind the
dust and leave the radiator squeaky clean.

I keep the pressure at 750 psi, but you could turn it up more if
needed. Again, the water temp, not the pressure is the real
difference maker. I set the water @220 f.

You will not hurt the motor. Infact, if the motor needs cleaning
blast away at it with the hot water and it will be as clean as the
radiator. Same goes for the generator compartment.

Remember, when you are finished, all the grease that used to be in
your bus will now be laying on the ground directly beneth it. Park
your bus in a good spot!

You can rent a hot water machine from an equipment rental place.

Good luck.
