Should you mix antifreeze with oil?

I have oil in the coolant

The lubricant is one of the car fluids whose revision is more internalized. Everyone knows the catastrophic consequences of not changing the oil or having the level below (or above) the recommended level.

How to check the level?1. Place the car in a flat and horizontal place and let the engine cool down, since the level is always higher when hot. 2. Take out the dipstick and clean it. 3. Put the dipstick all the way back in and remove it. At the end of the dipstick there are two notches indicating the minimum and maximum level: check where the oil mark is.

If the level is low… The best thing to do is to go directly to the workshop and ask for an oil change: cars, especially older vehicles, sometimes consume more lubricant than expected and it is advisable to change it every few kilometers.

The coolant fulfills a fundamental mission among the car fluids: it circulates through the internal circuit of the engine and absorbs part of the heat generated by combustion, thus preventing dangerous overheating. An excess of temperature could melt the pistons and even trigger a dangerous internal explosion.

Engine oil color with water

Can someone help me? I have a F650 GS Dakar 2006, the bike suddenly turned on the temperature light, then burst a hose from the water pump, I changed it and took it to the service for mileage and the mechanic told me that the bike had a mishap and had a blow to the radiator, the casing stopped the fan, the mechanic corrected the problem and tested the fan, the good thing is that it did not burn, leaving started with temperature problems and then mixture of antifreeze in the crankcase, I did pressure tests to the radiator and failed the mechanical seal of the water pump, this can cause the mixture of oil and antifreeze?

Well, I think you have a cylinder head gasket, although the water pump is mixed, which moves both coolant and oil with the same shaft, both circuits are separated, in addition to seals, by an empty space with a drain hole, as the photo of the previous answer.

This hole is to warn of a leak of oil or coolant or even both, but should never mix the liquids in this place, as before they go outside through this hole. You also mention that the temperature light came on and that you burst a hose and that the electric fan was seized. Normalmete these symptoms are typical of a calenton, due to lack of cooling by the electro, the temperature and circuit pressure increases to the point where somewhere has to burst and usually generate a failure in cylinder head or gasket, with q q is the possibility that is mixed by the head gasket.

There is oil in the antifreeze

A breakdown that can bring us many headaches is the mixture of oil and antifreeze. If when we go to check the levels of our car we find a mixture of oil and antifreeze in the expansion bottle, we can start to worry because, in principle, it is not a simple fault.

To easily recognize the mixture, when we open the cap of the expansion bottle we will see a slightly yellowish and viscous substance. If we check the oil level, it is also possible that it is not between the minimum and maximum.

In this case we find that somewhere in the engine the two liquids have mixed. The engine has several conduits inside it. Oil circulates through some of these ducts to lubricate the engine and antifreeze circulates through others, which is responsible for cooling the engine.

Another option, more economical, is that it is mixed in the oil cooler. The oil cooler, as its name suggests, cools the oil by means of the antifreeze used to cool the engine.

How to clean the engine when water passes into the oil

Antifreeze is a chemical consisting primarily of ethyl glycol. When mixed with water, it lowers the freezing and boiling point of the mixture. Unlike air-cooled engines, those equipped with a water cooling system have a radiator and other elements that help to even out the temperature.

Within the system, the antifreeze is transferred in a cycle driven by the water pump, from where it obtains the heat of combustion and transfers it to be cooled again. It also provides the hot air for heating the car, through another radiator, and the cycle starts all over again.

The concentrated antifreeze has not been diluted with water, unless the product label clearly specifies it. It contains the chemical elements that allow it to work better at extreme temperatures, but if we only add this antifreeze liquid to the cooling system, due to the hardness of its components, it can generate oxidation.
