How to wash a car engine?
I will say this, I am not a supporter nor a "KARCHER", no pouring of the power unit from the hose.
Do not wash the engine Karcher
I think this is wrong action (don't try to convince me). Indeed, in one case you pressure can tear all the wires, otherwise you can just fill in some necessary blocks (although the second method is more safe, because the hypothetical car, designed for wet weather and puddles).
BUT I have a third solution (drum roll) — it is a sprayer for trees. Yes, you heard right that he (the one designed for pest control on Apple trees and pears have probably all seen them). Here, water is distributed much more efficiently, you don't pour gallons of it do not understand where and why. The motor can be washed about 15 – 20 liters. And very efficiently. Has a swivel spout and adjustable jet (or spray, or beat with a jet).
I got it from mom, because a private house and there are trees, you can also borrow from parents or grandparents. Otherwise buy, it is not expensive. Version for 5 litres from 600 to 900,
Most importantly, he pressures not exceeding 3 atmospheres, personally, I always pump about two. It is really safe. Often the "nose" of the rotary, it can be directed at hardly accessible places.
And now step by step:
- Battery. Ideally it it is impossible to wet, and you need to remove the terminals (or at least terminal) to de-energize the body. If you find this problematic (you lose system settings), then it can be cover with a plastic bag (or wrap with stretch wrap).
- Block the air intake. The water in the engine is VERY bad (God forbid hammer), we therefore exclude the ingress of water into the intakes, they are also covered with cellophane.
- Chemistry. Many people make another mistake, what do you use when washing? Shampoo that is suitable for the body of the car, not suitable for the engine. Again, he may get into contacts, corny oxidizing them. You need special chemicals that are sold by the ton in special shops of cosmetics. For cleaners or shampoos for the power unit. I personally, for a long time from the company, LAVR, "foamy engine cleaner", it is easy to apply, works effectively, is not corrosive and washes off without problems. After it never got any CHECK ENGINE all worked as they should.
- To apply. Some of the tools work at 40 degrees Celsius, the other at 70 – 80 degrees. Some are applied to dry the motor, for others it is necessary to moisten. This should be considered for cleaning efficiency.
- Rinse. As I wrote above, no KERHARO and HOSES WITH WATER. Personally I use the sprayer (in the video version below, depicts the process).
- Blow. YES, it's desirable, that's only if you wash your hands, say in front of the garages, then take compressed air anywhere. And then I have a small tip for you — buy in any computer store (I personally take in DNS), any compressed air for the computer. And I'm with antistatic effect and the displacement of moisture here and take this. Clean the contacts like new will be + protected from moisture and dust buildup.
- Direct the clean. At the end usually put chernical rubber, all plastic parts and hoses. They take a deep rich color (a new).
- After washing. It is recommended for one hour — do not turn off the power unit. So it is completely dry, you can ride through the city at rush hour (to stand in traffic jams), everything will dry quickly.
