Cleaning Accord engine compartment (places to avoid getting water?)
 

I plan on cleaning the engine compartment of my 97 accord with 137,000
miles. I know to cover the alternator and obvious electrical
connectors. I also hear advice to cover the distributor, but from my
what I recall Honda 2.2 vtec engines are distributorless. Are there any
other parts of the engine compartment that I should be extra carefull
to keep water away from?
I plan to use Simple green, a low-pressure mist, a cold engine when
cleaning and to final rinse with distilled water.
Many have talked about what possibly can go wrong.
I would like to especially hear from others where something DID go
wrong when they cleaned under the hood and what they would have done
differently. Thanks

Do you mean there is no distrubutor cap and rotor and spark plugs? and
wires and coil wire??

All you need to do is cover all electrical wires and stuff with a
plastic sheet. Get a engine Gunk Cleaner can, and spray all over; wait
for 5-10mins and clean with water. Distilled water may be a overkill.
Make sure you do not start the car for 30mins. After cleaning, I also
spray a can of WD40, on all rubber parts and hoses for protection and
long lasting elasticity. Make sure you don't spray WD40 on belts.

please DO NOT spray wd40 on natural rubber - it rots it.

The fact you'll be avoiding high-pressure water almost guarantees
you'll stay out of trouble.

Do not apply WD-40 to any rubber or plastic since it's almost like
mineral spirits and can attack them, especially the water hoses, whose
EDPM rubber (also used for weatherstrips) is impervious to almost
everything except oils. Silicone oil (spray lube, many vinyl/rubber
protectants) is an exception, keep silicone from getting sucked into
the engine, such as through the intake or a vacuum leak (loose hose)
because it can ruin oxygen sensors. Actually EDPM rubber doesn't need
silicone oil because it's virtually impervious to UV rays and ozone.,
unlike vacuum, fuel, and brake hoses.

Wouldn't bearings also likely be damaged from a detergent solution?
For example, alternator bearings, electric fan bearings (if any), etc.

Also, what about mechanical fuel pumps (if equipped)?
They may have an air inlet hole, often on the upper half, which might
allow potentially damaging wash fluids to drip onto the pliable
diaphragm.

Oops, I am very SORRY !!! about spraying with WD40. What I meant was
SILICONE SPRAY and not WD40. Thanks for the correction GUYS !
