PPE Intercooler Coolant Heat Exchanger (2020-2026 GM LM2 / LZ0 3.0L Duramax) - (119010300
Overview
The PPE Intercooler Coolant Heat Exchanger is engineered to improve the cooling efficiency of the factory air-to-liquid intercooler system found on 2020-2026 GM 3.0L Duramax (LM2/LZ0) engines. By increasing core size and optimizing coolant flow, this upgraded exchanger helps maintain lower intake air temperatures during demanding conditions such as towing, high-load driving, or extreme heat.
20% Larger Core for Better Cooling
PPE increases the core size by 20% over stock, adding more surface area and additional coolant volume - about one extra quart - to improve heat transfer and reduce the likelihood of heat saturation. This helps the intercooler maintain consistent performance even during extended high-load operation.
All-Aluminum Construction
The heat exchanger features heavy-duty, all-aluminum end tanks and a fully brazed core for maximum durability. With 18.5 fins per inch, the high-efficiency fin design increases heat dissipation and overall cooling capacity.
Optimized Coolant Flow
PPE reworked the internal coolant tube layout to improve flow distribution and reduce restriction. The result is a 15% lower pressure drop compared to the factory unit, allowing coolant to circulate more efficiently and carry away more heat from the intercooler system.
Easy Installation
This heat exchanger is a bolt-on upgrade that installs using the stock mounting brackets - no grille removal required. It integrates seamlessly with the factory intercooler system and delivers immediate improvements in cooling performance.
Pair for Maximum Performance
While this unit alone significantly improves intercooler efficiency, pairing it with the PPE Air-to-Water Intercooler Kit provides the ultimate cooling package for the 3.0L Duramax, increasing charge-air density and overall engine performance.
