Why does my Promaster leak coolant?

Why Does My Promaster Leak Coolant? The sight of a puddle beneath your Promaster van can be distressing, especially when it's coolant that's leaking. A coolant leak not only poses a threat to the engine's health but can also lead to overheating issues and subsequent breakdowns. The two most common sources of coolant leaks in Promaster vans: from the surge tank and from the oil cooler on the Pentastar engine. Promaster Coolant Leak from Surge Tank The surge tank, also known as the coolant reservoir or overflow tank, plays a crucial role in the vehicle's cooling system. It is designed to collect excess coolant that expands as the engine heats up, preventing over pressure in the cooling system. However, when a coolant leak occurs from the surge tank, it can raise concerns about the cooling system's integrity. Several factors could contribute to a coolant leak from the surge tank: 1. Damaged Surge Tank: Over time, the surge tank ... read more

GMC Sierra 2500 Diesel EGR Cooler

GMC Sierra 2500 EGR Cooler The GMC Sierra 2500 Diesel is a powerful and reliable truck known for its durability and performance. One crucial component in its engine system is the Exhaust Gas Recirculation (EGR) cooler. The EGR system in diesel engines helps reduce emissions by recirculating a portion of the exhaust gases back into the combustion chamber. The EGR cooler is a vital part of this system, as it cools the recirculated gases before they re-enter the engine. This process helps regulate the combustion temperature, minimizing the formation of harmful nitrogen oxides (NOx) and enhancing fuel efficiency. There are two primary types of EGR coolers commonly found in GMC Sierra 2500 Diesel trucks: air-cooled and liquid-cooled. Air-Cooled EGR Coolers: These coolers use air as a medium to dissipate heat from the recirculated exhaust gases. While generally simpler in design, air-cooled EGR coolers may be prone to overheating, especially under heavy load conditions. Liquid-Cooled ... read more

Can I drive my Jeep with the ABS light on?

Can I drive my Jeep with the ABS light on?    Your Jeep is built to handle various terrains and challenges however, when the ABS, Anti-Lock Braking System, light illuminates on your dashboard it's important to have the vehicle inspected by a service professional.  What does the ABS light mean?  The ABS is a safety feature designed to prevent wheel lock-up during hard braking, enhancing control and stability. It achieves this by modulating brake pressure to individual wheels, allowing the driver to maintain steering control while braking. This is especially important when driving in South Florida due to frequent rain storms and aggressive driving habits which may cause frequent hard braking. When the ABS system detects a potential wheel lock-up, it intervenes by adjusting brake pressure multiple times per second, ensuring that the wheels continue to rotate, promoting optimal traction and preventing skidding. The ABS light on your dashboard serves as a warning ... read more

Can I drive my Jeep with an oil leak?

Can I drive my Jeep with an oil leak?  Traditionally engine oil serves as a lubricant, reducing friction between moving parts in the engine. It also helps dissipate heat generated during combustion, preventing components from overheating. Moreover on contemporary Jeep engine's specifically the Pentastar 3.2 and 3.6 as well as the Multiair Engine designs engine oil serves a hydraulic function to engage solenoids within the VVT system. Engine oil pressure is affected by temperature and volume and thereby a engine that is leaking engine oil may have a reduction in its ability to sustain oil pressure required for modern Jeep engines. As a note on engine oil pressure, Chrysler does allow for a lower threshold of 12 psi however in our experience an engine with oil pressure below 20 psi is worth monitoring for underlying faults.    How far can I drive with an oil leak?  The answer to whether you can drive your Jeep with an oil leak is not a strai ... read more
