How do you know if your car has leaks in its evaporative control system (EVAP)? The leak detection pump is especially designed to detect leaks in the emissions system by pressurizing the EVAP and measuring the time for the pressure to fill the system. If the time interval is short, this implies a serious leak in vehicle's emissions system. Your car's LDP can be located near the gas tank, and can only be accessed by partially removing the vehicle's exhaust system.
Why install a leak detection pump (LDP)?
Leak detection pumps play an important role in car maintenance. Most of the time, leaks can cause more complicated problems that take longer time and greater effort to fix. Finding these leaks before they cause more issues becomes an advantage to you as it will save you more money and time. LDPs are also important indicators that your car has a serious problem-serious leaks can cause fatal accidents, but with a functional LDP, you can avoid these accidents altogether. Other car leaks can also be harmful to the environment which is why a leak detection pump is necessary for any vehicle today.
What to expect from a leak detection pump (LDP)?
Most leak detection pumps nowadays use solenoid circuits for a more accurate reading of leaks. Some LDPs can measure even the tiniest leaks in your car's evaporate emissions system. When choosing the right LDP for your vehicle, make sure that it uses a solenoid circuit, and that it is sensitive enough to detect the smallest leaks. Cheaper leak detection pumps are mostly made of polymer-based materials that can break down due to intense pressure. If you're looking for durability, stainless steel LDPs are right for you, but budget-conscious drivers can always settle for polymer leak detection pumps.
