FITMENT:2018 2019 2020 2021 2022 2023 2024 Wrangler JL JLU & 2020 2021 2022 2023 2024 Gladiator JT 2.0T&3.6L Model.OEM Number:68364312AC/68364312AA/68364312AB/68388115AB DESIGN FEATURES: Compatible With Oem Installation Position, Compatible With Oem Cover, Reserved Pressure Relief Hole To Prevent High Pressure, Aluminum Alloy Material, Lighter Weight, Higher Pressure Resistance. FUNCTION：When The Coolant Pressure In The Radiator Exceeds The Pressure Cap Setting, The Coolant Flows To The Outside Through The Reserved Channel To Prevent The Water Pipe From Bursting, Which Is The Same Function As The Original Car Kettle. INSTALLATION：OEM Hole Installation Without Cutting. In the past, cooling tanks (POTS) made of plastic were often used in automotive engine cooling systems to store and circulate coolant. However, there are some problems in the long-term use of plastic POTS, one of the most common problems is water leakage. The plastic pot is susceptible to the high temperature and pressure of the engine, and the long-term thermal cycle will lead to the aging and fatigue of the plastic material, and eventually lead to cracks or water leakage in the pot body. This leakage can cause coolant to leak, which can cause the engine to overheat, damage or even not work properly. In order to solve the problem of leaking plastic POTS, automobile manufacturers and suppliers began to develop and adopt more durable and reliable materials, such as aluminum alloy, to make engine cooling POTS. Aluminum alloy has high heat resistance and pressure resistance, and can withstand high temperature and pressure under engine operating conditions. In addition, the aluminum alloy material also has good sealing performance, which can reduce the risk of water leakage. Therefore, the development background of the automobile engine cooling aluminum pot is to solve the problem that the original car plastic pot is easy to leak, to provide more reliable and durable cooling system components to ensure the normal operation and long-term reliability of the engine. This technology upgrade helps to improve the performance, durability and user experience of the car.
