CVTs are becoming increasingly popular with our drivers. But there are no fewer questions for the units. After all, this is a rather delicate knot that easily overheats, and this is easy to do even if there is asphalt under the wheels and no dirty slurry. The AvtoVzglyad portal tells how to save CVT and not get into expensive repairs.
The main problem of the variator is overheating of the working fluid. That is why it is so important not to operate the unit under increased load. After all, as soon as the liquid heats up to 80 degrees, problems can begin. And at more than 115 degrees there is a gradual degradation of the lubricant and the loss of its working properties. As a result, scratches appear on the rubbing surfaces, wear products, that is, metal chips are formed. It shuts off the control system valves and the high pressure pump. In this case, the CVT will go into emergency mode, as indicated by the overheat indicator illuminating on the instrument panel.
The main problem is that “frying” the variator is not that difficult. The easiest way to do this is to drive at high speed (130-150 km/h), for example, along the Moscow-St. Petersburg. A long, flat highway challenges you to go fast, causing the junction to overheat.
And in the city it is enough to move at high speeds, starting with skidding and more often “jumping” (also with skidding) on high curbs. But even if you drive carefully, problems do not pass. In winter, the “box” must be heated, but this cannot be done in the parking lot. The CVT only warms up while driving. Therefore, every driver is at risk. In order not to put out a lot of effort for the repair or replacement of the “varicose vein”, advanced “steersmen” install an additional cooling radiator on it.
By the way, many car manufacturers ignore such a “gadget”. The reason is that they want to reduce their own costs and rely only on a heat exchanger located on the housing of the unit.
Several independent manufacturers come to the rescue and offer complete kits for specific models. And for a number of crossovers, even more efficient radiators are offered. Such a “cooler” is quite effective and will certainly save the “varik” from a “heat stroke”. It also helps if the main intercooler gets clogged with dirt over time and the driver forgets to clean it.
