Car wash pressure safe for radiator.
I want to clean both my engine and radiator/cac. I have a self serve truck wash fairly close by. It's has big stalls for 18 wheelers. I'm primarily interested in using the facility to catch all the oily water that comes off the engine and radiator. I'm not able to do this at my house with a garden hose and have the water drain in the street. I bought some Simple Green HD and plan to use that with some dawn with a garden sprayer. The next step will be to rinse. I will be careful with the alternator and not get to close with the pressure on the fins. I'm curious what the pressure is at a car wash? Sound like a reasonable plan?
