cleaning?
hey guys, i was just woundering what would be the best way to give my engine/engine bay a bath?
as you can see its pretty dirty
would i be able to just run a hose over it or is there any thing that should not get wet?

Power wash works quite nicely. Just don't spray the water at things like the battery or spark plugs (wires or coil). It's okay if they get wet, just don't force water down them.

Yeah....spray it down with water, then spray degreaser on it, let it sit for a minute or so, and then power wash that sucker. Hot water also helps.
You'll need to seal off that intake or something....

SuperClean works very well. Just watch out on polished aluminum.
Also when you get done and its dry, spray everything down with spray silicone. It makes everything shiny and helps preserve rubber.

That's not true. Heated pressurized water with degreaser works fine.Bheinen74 wrote:the only real way to clean something like that is STEAM clean.
You don't really want to use steam as it will cause the rubber hoses and what not to become brittle prematurely.

On the contrary, although silicone spray will make everythig shiny, it will not preserve the rubber. The silicone will actually pull out the agents that keep the rubber flexable. This will make the rubber breakdown and deteriorate quicker than normal. Its far better to use a water based vinyl or rubber care product.napphappy wrote: spray everything down with spray silicone.

Very true. Do NOT steam clean.Legacy777 wrote:You don't really want to use steam as it will cause the rubber hoses and what not to become brittle prematurely.
I suggest covering things like the coilpack, fuel injectors, battery, alternator, and any other obvious electrical instruments with plastic bags before you hose the whole engine down. You can clean those separantly with Armor-All.
This comes from someone who washed down his engine and then had 6 CEL codes when he started the car back up

When I said steam clean, that means heated water with degreaser cleaner.
The heated water is hot yes, but not any hotter than what the engine runs when going down the road. It will definitely not harm anything.
It is best to pressure wash the engine when it is at full engine operating temp. This will sort of make the water evaporate from the electrical areas faster. Also, it is better to run the engine immediately following, until it is warm and evaporates all the water off completely, and burns off any moisture in the deep hidden areas and hollow spots.
Never spray silicone, or for that fact much else on the engine, as that stuff attracts dirt and will only make the engine dirty faster.
You have to be careful around all the electrical stuff, connectors, alternator, battery, coil pack. Go over that stuff really quick and don't soak that stuff down at all.

How to Use
Using the "spray anywhere" nozzle, spray directly on brake parts and allow to dry or wipe and clean. Do not spray on automotive finish. May be harmful to plastics. Protect rubber parts from overspray. "

Driving a Chevy Astro or other van with the doghouse (engine cover) off demonstrates how much heat and airflow goes thru an engine compartment. Can feel the heat coming off the motor right after hard acceleration. Must be pretty hellish sitting behind a WRC or NASCAR motor in competition. I would go for a high speed drive right after spraying water on the engine to dry things off.

Be careful with the knock sensor. Who ever said to run the motor to operating temp and then spray it down. Knock sensors tend to fail when they are hot and then get real wet, regardless of the fluid temp.

yeah I would not recommend the engine be to hot when cleaning especialy if you're cleaning with cold water. If you have hot water (car wash) then the engine can be warm (not running).

Do it in your own driveway - not at a car wash - in case the car won't start afterwords. We get a lot of threads where people wash their engine and it doesn't run right or won't start until it dries out.
