Engine preheater alliance installation

Car electric heater alliance installation diagram

In search of means to ensure easy starting of the power plant in conditions of low temperatures, many car owners choose antifreeze preheaters, working on 220V network. In such devices powerful heating elements provide sufficiently fast heating of the motor in winter. At the same time, motorists often give preference to such devices of domestic production, among which is a preheater “Alliance”.

Such decision is often explained by the fact that domestic devices are cheaper than foreign ones, with tolerable quality of assembling and acceptable performance of their functions.

This manufacturer appeared on the market of power plant heating equipment quite a long time ago, and its products are in demand.

Wiring Diagrams

Each type of model has its own connection diagram, which must be followed, otherwise the antifreeze will not circulate (applies to gravity models).

There may be several variants of cutting the heater into the system. For example, on some cars the classic connection scheme is used, when the fluid is fed from the hole for drain plug (instead of it a pipe joint is installed), and the output is on the upper pipe from the radiator (T-piece is installed).

But more often a slightly different wiring scheme is used. In it the antifreeze is fed through the same drain plug, but the drainage is made into the hole of the cylinder block thermode. For such a connection, the unit comes with a tee fitting. It is screwed in instead of the temperature sensor. The sensor itself is then screwed into the butt end of the connector, and the pipe from the heater is put on the side outlet of the tee.

What is it for and how is it built?

When the engine is started after a long standstill, for the first few seconds the parts touch each other without lubricant. The viscosity of cold engine oil is higher than in the temperature range of the engine. That’s why it takes some time for the lubricant to get through the narrow oil lines to the engine parts. Particularly affected by the cold start piston group parts. Thus, starting cold engines shortens their service life by up to 1.5 times. To avoid this, as well as to facilitate starting the engine in cold weather, are designed preheaters, powered from 220 V.

This device is able to warm up the engine in 30 minutes even in severe frost

Structure and operation of the preheater

Modern heater is designed quite simply and does not differ much from the boilers. Its working principle is to heat the coolant (antifreeze, toluene) to a working temperature, ranging from 60 to 70 ° C. The fluid heats up and begins to move along the cooling system nozzles, heating up the engine parts. To speed up the heat exchange, many models are equipped with pumps that create pressure in the small circuit of the cooling system.

To create pressure due to the temperature difference, the heaters without a pump are connected to the cooling system at its lowest point. The unit with the pump can be connected to the cooling system anywhere. When the temperature reaches the set point, a relay will simply switch off the heating element. If the temperature drops again the relay switches the heating element back on. Thus, you can connect the device in advance, without the fear of overheating the coolant.

In addition to heating the engine cooling jacket, heaters can parallel:

It is possible to connect the heaters with and without pumps

Heating elements capacity varies in the range from 500 Watt to 4 kW. Set of additional features depends on the model and completeness of each such device. There are also fairly simple heaters that are screwed into plugs or drain plugs of engine cooling systems.

Scope and variety of models

A simple device and low cost are the main advantages of 220 volt heaters, compared to their other varieties. These devices can be independently installed on any car. It is only necessary to determine the mounting of the device in the under-hood space and follow the manufacturer’s installation instructions. The only condition limiting the scope of application. mandatory presence of electrical outlet nearby.

There are models with remote control, where you can set the temperature of heating fluid and timer heating time

Such heaters are best suited for private homeowners or car owners who live on the lower floors of high-rise buildings. Those who have a nearby garage with connected electricity will also be satisfied. Because the electric heater can be controlled remotely, from a distance of up to 1 kilometer (in direct line of sight). If there are obstacles in the way of the signal, the distance is greatly reduced.

Installing a heater on the 3020

Today car owners can buy starting preheaters, both Russian and foreign-made. Popular among motorists Chinese devices “Lunfei”, as well as the Norwegian DEFA. German Webasto heaters are not very convenient because of the complexity of installation, moreover they are expensive. Among Russian-made products can be noted brands “Severs” and “Start”, which are produced with sets of installation parts for domestic and foreign car models. Each model has its own set of mounting parts along with installation manual.

Depending on the volume of the engine, you can choose from 1 to 3 kW

Types of heaters, features

The company offers a choice of models with different design and technical characteristics. In most cases the units are designed for use on domestic passenger cars and trucks. VAZ, GAZ, UAZ, GAZel, etc. But the installation of heaters “Alliance” is also possible for foreign cars.

Catalog of preheaters of this company includes models:

“Alliance-2-PC

The only model in the list of the tank type, which includes a pump that circulates coolant through the system while the heater is working. Thanks to it provides more uniform heating of the cylinder block. The equipment has a vertical design. The power of the heating element is 2 kW;

“Alliance

This model comes in two types, 1.5 kW and 2.0 kW. Externally, it is identical to the model with a pump, but this version has no pump. Liquid circulation. gravity;

Horizontal flow-through model with perpendicular outputs. Designed for installation on the cars with shortened return pipe of cooling system and angular inlet of antifreeze on the thermostat body (VAZ of standard models and some front-drive models). Heating element capacity is only 0.7 kW, so it is more suitable for temperature maintenance, but not for cooling fluid heating;

“Alliance-08” and “08 Universal”

Flow-through model with horizontal leads. The first version is designed for installation on GAZ cars, but the second one is universal and can be used on foreign cars. Heater power. 0,8 kW;

“Alliance 3

Horizontal tank-type model with perpendicular leads and 3 kW power. This heater is designed to be used with truck engines;

The type of device affects the principle of operation. If everything is clear with a tank heater, equipped with a pump. when the pump is turned on, it provides circulation, then the gravity heater should be considered in more detail, because the scheme of its functioning is quite interesting.

Example of a home-made heater

Heater operating principle is based on free circulation of cooling fluid in a closed loop cooling system. Liquid heater is built in parallel to the radiators. Accelerated circulation of liquid will provide an additional pump, where the natural speed of the fluid is not enough.

In order to make the engine electric heater with your own hands, you will need:

  • Piece of pipe. One end will need a hole for the installation of heating elements. Holes are prepared in different ends of the pipe for installation of fittings.
  • Electric heating element. Power output is selected based on engine size and lube system capacity. from 400W to 2kW.
  • Two nozzles taking into account diameters of pipes of cooling system.
  • A piece of cable and plug to connect the heater to 220V network.

The assembled construction requires an inclined installation. This ensures the movement of the antifreeze. In addition, before installing the heater provide its thermal insulation.

Operating principle

The idea of the engine preheater is simple: since the engine is filled with antifreeze, heating the antifreeze from an external source, it will be possible to evenly heat the engine itself. Working gaps between the parts will normalize, the oil will warm up (it will heat up in the oil pan from the heat of the crankcase and in many cars after start it will pass through the oil and leaner heat exchanger) and the inlet manifold. For diesels and engines with distributed injection it is less relevant, carburetor engine warming up the manifold and the carburetor itself in the area of the idle stroke system jets is necessary. Part of the heat will give the engine and gearbox, which is also important. After getting in the car, you can immediately turn on the heater and defrost the windows.

Preheaters are divided into two categories

The simplest electric starting preheaters are heating elements in metal pipes, cut into the radiator lower pipe. Such designs are homemade because of their simplicity, in the northern regions of Russia you can see cars with a 220V plug sticking out from under the hood. In Northern Europe you can even find parking lots, where every parking place has a post with a socket.

The disadvantage of this is also clear. the heating is slow due to the lack of forced movement of the liquid in the circuit. It is avoided by introducing additional electric pump in a cooling circuit, but the necessity to connect preheater to external current source remains. But electric heaters don’t loose their popularity, there are interesting models that heat the engine and simultaneously charge the battery.

Liquid (autonomous) heater is connected to the electrical system, fuel line and cooling system.

Webasto Coolant Heater. Medium Duty Application

But how to heat the engine, when there is no socket nearby? The only option is to burn your own fuel. This is how autonomous starting preheaters are built: they are small heaters, which burn fuel, taken from the tank, and heat the built-in heat exchanger. Such preheater is easy to automate. connect a timer to it, the control output from the alarm. Because of this on a commercial transport such models, at which you can even set a weekly heating schedule, are set from the factory, and the name of the manufacturer of autonomous heaters Webasto repeated the fate of “Xerox”, becoming in the spoken language synonymous with preheating systems.

Of course, there are some disadvantages of autonomous heaters:

  • First, they need fuel. with an almost empty tank you will be left with a cold car.
  • Exactly the same way they need the battery charge. with an old battery the engine will get warmed up but the starter will not crank it any more.

For this reason, many heating systems integrated with on-board electronics automatically lock up when the fuel level or battery charge drops below a critical level.

The fantasy is not limited to this, but its other fruits are more like curiosities. For example, heat accumulators have been invented, which are thermoses that store a certain amount of coolant. While the engine is running, the thermal accumulator is included in the common circuit and heated to operating temperature; when the engine is shut off, it shuts off, storing the heat in it. By starting a cold engine, the driver gets a dose of antifreeze that retains heat. It is difficult to take such developments seriously because of the small “shelf life” of the heat reserve and because of the size. But they manage to sell. these are Canadian systems Centaur, and Russian “AutoTherm”.

Recommended: Minimum thickness of the brake pads

If to recollect unequivocally useless devices, it is the oil heaters, inserted through the dipstick. Not to say about ineffectiveness of oil heating in the oil pan, and the power of such “heaters” is so paltry that they can’t heat oil, uselessly draining the battery.

Hoses are g. but they don’t last long, dry out and burst at the most inopportune moment.

engine, preheater, alliance, installation

Hello. I bought a companion called. advise me, how better to install it on gas 53, because in winter the “crooked” one warms up instead of the gazi.

Feed comes from the block, output goes to the pump, that’s it !

I also installed it on a 409, although the manual suggests the heater hoses

hello. I bought a “satellite” called. advise how best to install it on a gas 53, because in winter, “crooked” himself instead of gazik warm up.

put on the gas 53? Where exactly is the inlet and outlet?? How’s the effect?? I also want to put

on gas 53 the drain is on the blocks. The thermostat is weak

And if it takes 1.5 hours to get the temp up to 70, what the hell is the need for it?? at least 85 degrees to be easy to start I also ordered myself but hope for 85 degrees to be less likely to rush the engine.

That’s great, man. tell me if it helped? How long does it take to warm up??

So I put it in, in the freezing cold.34, today the temperature of the head block (outside), 5 degrees 10, the heater is all night. How much frost is in your area??

_ good luck and warmth to you all ! I have been using these heaters for a long time, it’s a very good product, in the instructions of every pump there is a scheme of how and where to install it, and how many hours of operation it is designed for. I say at once that it is better to take with a pump built in heaters and also take Chinese brand LUNFEY, they are better and more reliable than others. If we talk about Volgovskoye 402 or 406 engines are better to take a 2000 watt it is designed for the volume of up to 3 liters. Look at my blog about the installation. And the Lunfei has a protection relay against overheating of the coolant in many of them is not. It’s better if it works through a timer outlet. You set the time to start and stop the heater all night long, I do not recommend quickly burning it out.
