Hello All..Question for all....I want to degrease my Engine 89 Blazer 4.3....Is there any parts that i should cover, wrap or remove in order to AVoid any water related issues...Any and all suggestion will be greatly appreciated...

 

Mostly just the distributor and intake. Don't want water in either of those. Pick up a can of STP Wire Dryer, it rocks.

 

You will also want to throw a plastic bag over the alternator as well just as a precaution. Really, everything under the hood can get wet, but you wouldn't want to put a direct flow of water onto the alternator or those things mentioned above.

**EDIT - Oh and Simple Green mixed 10:1 (10 parts water to 1 part simple green) workes wonders on a greasy engine. Plus, it isn't all that expensive and environmentally friendly (or more so than other degreasers)...

 

I find that spraying wd40 on all wiring harness plugs helps out a lot also

 

I wash mine at the car wash. I use the low pressure setting unless it is really muddy. Then I will hit it with the high pressure hose. I leave the engine running and try to avoid the distriburator cap and intake. To degrease, I use the tire cleaner.
