The controversy over washing/not washing the engine is as old as diesel/gasoline and as popular as Apple/Samsung. However, the answer is on the surface: who gives a guarantee for work – he washes correctly. And how this process goes at dealer gas stations, who always sign a piece of paper with a blue seal, tells the AvtoVzglyad portal.
A topic about cleaning the engine bay regularly gets “swing” on every forum: someone washed it but ruined it, someone succeeded and the other had a neighbor who generally burned the whole car and washed the oil slick from the oil pan . There are many opinions, everyone is right, there was no equality, and no. One conclusion, however, is undisputed: a clean engine lasts longer and performs better than a dirty one. The only question is how to achieve this result.
In garages or in a regular car service, they prefer to refuse the procedure, because there is certainly a risk. At the car wash – easy, but the responsibility lies with the owner of the car. If you want, we’ll do it, but bribes are lenient. Wax, polish are regularly offered, but washing the engine compartment is not. Did you pay attention? And how do they do that at official dealers who give a guarantee on all work performed? The “officials” have three rules that must be followed to get the desired result and “do not fail” in the subsequent repair.
The first point is preparation. No one will give head to cut that engine bay wiring will survive contact with water. But no stress, no problem. Therefore, the battery terminals should be discarded and it is better to remove the battery completely. The generator and starter also do not like baths, so they must be cleaned by hand, with a brush and covered with polyethylene before being treated with water. Same with the coil.
Second. Let’s face it: DIY chemistry, which is sold in every auto parts store, only helps with dust in three out of four cases. It does not remove stains from oil and liquids. But here the fairly ordinary Vinet detergent can cope – effectively and cheaply. A liter of concentrate is sold in any hardware store, it costs 350 rubles, and it is enough for ten engine compartments.
Vineta has another important property: it is absolutely harmless to wiring, rubber and plastic parts. Of course there will be “age-old layers” that won’t give up so easily. Another favorite compound of auto mechanics will help here: brake cleaner. This liquid is not cheap, but confidently copes with all “tough stains”. Without exceptions.
The third and final chapter is the process itself. The engine is not washed cold and not hot, but warm. The ideal temperature for cleaning is 30 degrees or the first limit value on the appropriate instrument scale. They applied the product, covered the “pain points”, rubbed it with a brush, washed it. Numerous videos in which the engine compartment is washed with water under pressure are only relevant for new or very young cars: a used car will not endure such torture, immediately confusing the driver with a variety of symptoms. It’s not worth the risk, so it’s better to be more careful with a brush, but lower the pressure in the hose.
This is followed by drying: both by standing statically in a warm room and by compressed air. The more thoroughly the mechanic “blows” each element, the less likely it is to have a headache. After — warm-up and diagnostics.
Taking this method of cleaning the engine compartment as a basis, you can not only get a clean and beautiful engine that heats up and cools down as the engineer intended, but also does not “break wood” with wiring, electrics and other expensive elements , which will have to be restored at a cost of all other investments.
