Where is the Mitsubishi 4A91 engine exhausted after adding coolant

Hello, Mitsubishi 491 does not need to exhaust air directly plus can be expected!

The car's heat dissipation (cooling) system is a closed circulation system in which the circulation of coolant helps the engine dissipate excess heat (keeping the engine at around 91 to 93 degrees). When there is air in the circulating system, it will block the normal circulation of coolant, reduce the cooling effect, and make the transmitter high. When a certain amount of air is reached, the pressure in the circulating system also increases.

1. The light one breaks the water pipe, and the water pump seals. 2. Heavy cases will damage the cylinder mattress. 3. No matter how serious it is, it will cause the abnormal expansion of the engine cylinder and piston (that is, the cylinder expansion is often called), thereby damaging the sending machine.

4 The high temperature of the engine will also make the lubricating oil lose its lubricating effect, which will aggravate the wear and tear of the engine. (Automobile coolant should be checked frequently and replenished in time.) When the engine is at a high temperature, do not open the water tank cover immediately to prevent being scalded by hot gas)

The general model is self-circulating and does not need to exhaust [If the car has a problem, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Turn off the engine, open the water valve or bury it is to unplug the water pipe, add new antifreeze while putting the old one, and wait for the new coolant to flow out, close the drain, start the engine, and then continue to replenish the antifreeze until the wind accompanies the fan to open normally [If the car has a problem, ask the car master. 4S shop professional pants messy ant technician, 10 minutes to solve. 】

Turn on the engine after filling up the antifreeze, and turn off the engine after the antifreeze starts to circulate, at this time you can't open the antifreeze filling port, otherwise the antifreeze will overflow. Wait for the engine to cool down (i.e., after the antifreeze has cooled) and then refill it, possibly two or three times. During this time, check the height of the antifreeze every morning before leaving the car.

You don't need to exhaust air to add coolant, just take a car first, go idling, and then add it when the water temperature rises.

Hello, there is no exhaust where you can dismantle the heating wind and water pipes.

Look at the cooling fan to see if there is water under the water, if not, you can remove the water pipe and drain the water.

4G15 is Mitsubishi's very backward power! In fact, it is a 4G18 shrinking cylinder! There's not even much technology to speak of!

In front of many independent engines in the Chinese market! He looks very backward! And the engine of the 4A9 series is a relatively new technical engine from Mitsubishi!

A maintenance-free timing chain is used. Variable valve timing and lift. and other more mainstream technologies!

Compared with the backward 4G18, 4A91 is much stronger! However, it can't be compared with Geely, a domestic independent brand! In terms of power, it is not as good as Chery's Acteco!

It's just a little stronger than 4G18 or 4G15!

Yes, the all-aluminum engine with adjustable valve timing produced by Shen Hang.

1. First open the liquid filling port and then open the drain valve, (generally under the water tank) drain the antifreeze, then add antifreeze, wait until the drain valve begins to flow out of new antifreeze and then tighten it, start the engine when the antifreeze kettle is added to the scale mark, the antifreeze liquid level will slowly drop, you keep adding until it is stable, check it the next day and then continue to the scale mark.

2. Circulation method professionals to do, the return pipe is disassembled, the kettle is added, the engine starts, and the old antifreeze is circulated with new antifreeze until the new antifreeze flows out of the return pipe, and the color can be seen.

Yes, all cars have antifreeze added to the coolant. As for how much to add, it is decided according to the minimum temperature in the region. This is a technical job, and you need to know the proportion, because the ratio determines how many degrees below zero can be prevented.

But I suggest that you, in order to save trouble (because the ratio is to add distilled water), you simply clean all the water in the water tank and engine waterway, and directly add antifreeze, no need to mix, instead of cooling water. Such benefits are not only trouble-free, but also have a high boiling point in summer. But your car has only traveled 6,000 km, has it?

It should be regarded as a new car, and the antifreeze added when the new car leaves the factory, if all the antifreeze can generally withstand the low temperature of minus 30 degrees. It is not recommended that you replace it, and if it is lacking, you can add some appropriately. The standard added is between the two tick marks of the cooling kettle, between the highest (max) and the lowest (min) will do.

Too much is harmful.

Add it to the engine oil, and if you want to be professional, ask the repair shop.

No.

First of all, the service life of antifreeze is still within the shelf life, at this time it is found that the content of antifreeze is relatively small, if it does not meet the standard, it is possible to continue to add antifreeze, but such antifreeze is also to be added according to the standard of their own car, can not be mixed, otherwise it will not play a relevant role, and will affect the service life of the car.

Car antifreeze is less that can be added directly:

1. Antifreeze is also known as antifreeze coolant, as the name suggests, its functions mainly have two functions: antifreeze and cooling;

2. Because the temperature of the engine is too high and the boiling point of the antifreeze is very high, it can effectively prevent the engine compartment from exploding;

3. If in winter, because the freezing point of antifreeze is very low, then the cooling system can be protected from freezing at this time.

After the engine is naturally cooled, add coolant (do not add coolant immediately to prevent secondary damage caused by thermal expansion and contraction of the engine), and drive to the nearest repair shop for inspection.

1.Repairs are required, and this situation is caused by damaged cylinder gaskets, high engine temperatures (damaged water pump, damaged electronic fan, dirty water tank, damaged thermostat).

Smoke in the cabin means that something is broken or about to break, add cold liquid and go to the overhaul factory to see, there must be something that needs to be repaired.

Add coolant and hurry to the garage to check!
