A simple compressor in the trunk of any car is not only suitable for inflating tires, but also comes in handy when repairing a car. More precisely, during the diagnosis. And about how exactly to use a car pump, while saving hard-earned money, the AvtoVzglyad portal tells.
When antifreeze slowly leaves the expansion tank, the motorist begins to noticeably nervous. Of course, this may be due to the banal boiling of the “slurry” or its leakage through the nozzles. But sometimes the reason is much more serious – burnout of the cylinder head gasket. To determine this without disassembling the engine, the mechanics devised a tricky diagnostic method.
Allow the engine to warm up to operating temperature first. We disconnect high-voltage wires and unscrew one of the spark plugs. Next, we set the piston to top dead center (it is necessary for the valves to close) – this can be done by turning the front wheel, having engaged fifth gear. Of course we do all the work on a jacked up car. Then we lower the body to fix the “iron horse”.
Next, take the pump or compressor. We put some kind of rubber bushing or wheel valve from tubeless tires on the tip and press it against the spark plug hole. We blow! If at the same time air bubbles appear in the expansion tank or the liquid “bubbles”, it means that the gasket has burned out and urgently needs to be replaced.
And in order to understand the extent of the damage already caused, we unscrew all the spark plugs and assess the condition of the cylinders using the so-called domestic videoscope. It is sold in most online stores and works with a smartphone. It turns out a camera that allows you to see the internal state of the walls of the cylinders. Is there any moisture in any of them? It’s right in the packing.
Note the condition of the oil. When mixed with antifreeze, it clears and an emulsion appears on the oil filler cap and dipstick. The engine in this state will not be able to work for a long time, so you need to urgently repair the car.
