The work consists of several successive stages. The first is the selection of reinforced hoses of the required length, tees and a clamp. Without experience, we do not recommend doing this on your own - it is better to go to the car forum for your car model and look for relevant topics.
Extreme cold or heat are not uncommon factors that accompany the operation of a car in different regions of our country. And if an ordinary motorist can cope with the last trouble by simply turning on the air conditioner, then it is more and more difficult with frosts. But in this case, there is a way out. Today we will tell you how to properly put an additional pump on the car stove. It is she who will save you from the cold, making every trip by car noticeably more comfortable!.
What are pumps
This is the name of a simple vane-type pump with a mechanical or electromechanical type of drive. It rotates due to the timing belt (VAZ, some Renault, VW models) or the belt of mounted units. Some automakers prefer an electric pump. The standard pump is connected to the coolant temperature sensor and the speed of its rotation depends on the degree of heating of the antifreeze.
Vane type pump
The pump, being built into the circuit of the liquid cooling system of the engine, drives the coolant through all pipes and the engine jacket, removing excess heat and facilitating its dissipation through the common and radiator of the interior heater. The faster the impeller spins, the faster the excess heat energy is removed from the stove.
Why do you need an additional pump
Contrary to popular belief that this "accessory" is necessary only for cars operating at extremely low temperatures, in reality everything is somewhat different. The additional pump has more functions:
- increase in temperature in the car;
- if properly installed, it is possible to improve the heat transfer of the cooling system of machines operated in extreme heat.
Where is the extra pump installed?
Here, the recommendations of the "experienced" vary depending on the purpose of the installation. If the installation is designed to increase the temperature in the car interior in winter, it is correct to put it on a small circle of coolant circulation. When you need to improve engine cooling and increase heat dissipation from the engine compartment radiator, you need to embed the pump in a large circle. The section of passage of their nozzles must be found by studying the operating instructions for your machine.
Additional pump
The location of the correct installation of the duplicate part can also be different, but experienced motorists advise installing it:
- Near the washer reservoir - more suitable for Russian vehicles, because there is enough space here.
- Near the battery area.
- On the motor shield. Often, studs suitable for installation come out here.
How to install an additional pump on the stove
The work consists of several successive stages. The first is the selection of reinforced hoses of the required length, tees and a clamp. Without experience, we do not recommend doing this on your own - it is better to go to the car forum for your car model and look for relevant topics. There you will find a detailed list of everything you need. Having prepared everything you need, let's get to work:
- We cool the engine to a temperature not higher than 30-35 ° C. If it is higher, it is easy to get a thermal burn.
- Drain the antifreeze using a clean container.
- We attach an additional pump.
- We cut into the cooling circuit through a system of tees. We draw your attention to the tightening of the clamps - do not overtighten them, as you can cut through the hoses.
Installing an additional pump on the stove
After that, you need to connect the unit to the on-board power supply. Do it better through the relay. We connect the mass wire of the winding to ground, we lead the power wire of the relay to the motor connector, we also pass the positive wire through the relay unit, along the way "hanging" a fuse of the required rating on it. After - we connect it with a plus from the battery. For ease of use, we advise you to insert any suitable switch into the gap in the positive wire - it can be mounted on a dashboard or central tunnel.
Which pump for the stove is better to choose
Despite the apparent diversity, a suitable option is a detail from the Gazelle. "Additional" from it is very cheap, compact enough, productive. You can choose the right spare part from a foreign car, but their cost is many times higher. Their plus is that foreign manufacturers are trying to supply better quality products to the shelves of Moscow stores. Buying a part from GAZ can turn into a lottery. Sometimes you have to go around more than one store to find something suitable.
What is important to consider when operating additional pumps
There are no special nuances, but remember that at temperatures below -35 ° C, you first need to let the engine warm up properly, and only then turn on the additional electric motor. Otherwise, the engine may not warm up to the required performance. When operating the machine in heat over 35 ° C, the additional drive can be constantly “driven”. By the way, in such situations, we recommend installing a more efficient under-hood radiator fan in the kit for the pump - this way it will “supply” more heat to the environment.
When installing this unit on a diesel vehicle, remember that it is better to turn it off at idle. Heavy-fuel engines tend to cool down gradually in winter, and with improved cooling, this will happen even faster.
