Worn hoses or a defective Gazelle radiator become the main cause of fluid flow in the vehicle interior. If this happens, you will need to purchase a set of pipes and a new heater cooler. A copper radiator is considered more effective, but it has a higher price compared to the aluminum version.
Features
Do-it-yourself replacement of the Gazelle radiator will require compliance with certain rules. To change the stove on an old-style model (older than the Business modification), removing the entire panel is optional. The part is located behind the central part of the torpedo, which will have to be dismantled. It is worth noting that the plastic protection is fixed on special mounts (caps).
Before proceeding with the dismantling of the element, it is necessary to drain the coolant, unscrew the clamps and remove the hoses. The part is screwed with three screws. After removing the old element, you need to carefully clean the installation site from debris, scale and other pollution. At the same time as the radiator, the nozzles should be changed, which will extend the life of the new element.
At the end of the work, new antifreeze or other coolant is poured, the power unit is launched and the entire system is pumped. To do this, you must open the exhaust tap.
Replacement instruction with motor ZMZ-406
Replacing the Gazelle radiator itself is quite simple. The following manipulations should be performed in stages:
- Disconnect the connector of the fan motor (EV), disconnect the pair of wires from its sensor.
- Loosen the clamp and remove the hose from above and below the pipe.
- Remove the steam outlet and remove the radiator.
- If necessary, you can replace the shock absorbing pillows.
- Unscrew the nuts of the fastening of the EV (4 pieces).
- Remove the electric fan and its inclusion sensor.
- The cap and rubber seal are removed.
- The drain tap and fixing bracket are removed from the old radiator.
- All elements are mounted on a new part, which is mounted in the reverse order.
How to install a Gazelle Business radiator
In this case, the task looks a little different, when replacing the element in question, you must perform the following steps:
- Loosen the clamp with a screwdriver and remove the hose connecting to the expansion tank, as well as a similar element of the upper pipe.
- Remove the fixing nuts and move the cover to the side.
- Remove the radiator and fan cowl.
- Remove the plug, drain cock and mounting bracket.
- Rearrange these elements on a new radiator.
- Assemble in a mirror sequence.
Characteristics and Application
The Gazelle radiator has the following technical specifications:
- Material and type of execution - brazed model made of an alloy of brass and copper.
- The row number is three.
- The heat transfer rate is 83 kW.
- The weight of the standard modification is seven kilograms.
- The manufacturer is the company Avtomash Radiator.
The considered variation is used in Gazelle-business class cars (power unit - UMZ-4216). In addition, there are analog models made of copper: GB-330242, 33027Sh, 330242-1301. Aluminum options: 33027 - 1301010 / 1301010-33.
Modernization
The Gazelle car, popular in the domestic space, the installation of a heating radiator on which it is not particularly difficult on its own, can be modernized in this part. The following describes the process of improving the site under consideration.
Due to certain design flaws in heating systems, the Gazelle car does not heat up too much, it is cold in winter, especially when driving in open areas. This is due to the fact that cold air is constantly circulating in the central ducts. Experienced drivers often in the cold trim them with tape or rags. In fact, you can make sure that the heat not only leaves, but also arrives.
For this, it will be necessary to install an additional radiator element at the inlet in a standard furnace. The torpedo is removed, all hoses and cables are disconnected, the main radiator is dismantled and an additional analogue is installed on the air intake part. For example, you can use a radiator from a VAZ stove. The maximum that is required is to cut the fittings.
Tuning Efficiency
After the installation of the additional installation is completed, you can also adapt the electric pump. It is mounted under the hood, behind the heater control faucet and in front of the standard radiator.
You can turn it on directly from the dashboard, you only need to bring out the corresponding button or toggle switch. Both installed radiator elements are connected in series. When an additional pump is activated, the circulation increases and the hot coolant, passing through two radiators, perfectly heats the interior of the car. If it is very cold outside and the engine is losing heat intensively, just turn off the pump. After installation of a similar design, as practice shows, it is warm in the cabin even at an outside temperature of minus thirty.
Below is a graphical representation of the size of the Gazelle radiator.
Pros and cons
When replacing the radiator unit of a Gazelle car, the conditions for using the car and the climatic features of the region should be taken into account. Copper models have a higher cost, but they are more resistant to tearing and corrosion. In addition, they heat up quickly and keep the temperature well.
Aluminum variations are suitable for temperate climates, where there are no sudden changes in temperature. In harsh climates, it is better to use a modified model with an additional radiator and pump.
To independently replace the assembly in question, you need to stock up with a set of screwdrivers, wrenches, pliers, new clamps, a crowbar, or a small crowbar.
Completion
The Gazelle radiator is not difficult to replace on its own. Do not ignore the timely maintenance of this unit, as it is responsible for the heat in the cabin. At the first sign of leakage or in the case of obvious signs of structural wear, it is recommended to replace the part. Following all these steps, even a novice motorist will cope with this work.
