at my carwash we always clean the engine with it running - be very carful with the pressure washer - we use a low psi (around 300-400) not the usual 1200psi. when the engine is running its less likely to get water where it's not susposed to go. we clean about 10-15 engine compartments per week, and never once in 5 years had a problem! jeff bednar fountain car wash ----- Original Message ---- From: Brian Denning <i_am_cool_fred@xxxxxxxxxxx> To: tcb@xxxxxxxxxxxxx Sent: Friday, November 2, 2007 12:46:38 PM Subject: [tcb] Re: Cleaning the engine bay as long as the electronic stuff is covered it's fine...i did mine once with the motor in it and it didn't hurt it at all...i wouldn't recommend doing it with the motor hot though From: treyjung@xxxxxxxxxxx To: tcb@xxxxxxxxxxxxx Subject: [tcb] Cleaning the engine bay Date: Fri, 2 Nov 2007 12:33:38 -0500 How dumb is the idea to pressure wash the engine compartment with a pressure washer with the engine still in the bus? I'm thinking cover the engine (generator is my main concern) with plastic and go after it..... It's just really dirty back there..... Anything I should be aware of that I need to worry about?
