Intercooler Coolant Heat Exchanger for GM LM2/LZ0
The GM 3.0L Duramax utilizes an air-to-liquid intercooler to keep its intake air cool. However, the stock intercooler’s performance is largely dependent on the efficiency of the front-mounted coolant heat exchanger. This heat exchanger absorbs heat from the intercooler coolant and dissipates it to the ambient air. If the heat exchanger becomes heat saturated, it will greatly impact the efficiency of the intercooler, and affect engine performance. Heat saturation can result from prolonged high-load operations such as towing, or extreme ambient temperatures.
PPE overcomes the heat saturation issue with our High-Efficiency Intercooler Coolant Heat Exchanger. It features a 20% larger core and more rows of fins compared to the stock unit, adding about one full quart of coolant to the system for improved efficiency and heat stamina. The fully brazed, 18.5 fins-per-inch core and all-aluminum end tanks further boost its heat dissipation effectiveness. We have also optimized the two-row coolant tube layout for better coolant flow distribution. The pressure drop across the PPE heat exchanger is 15% lower than the stock unit, resulting in a higher coolant flow rate and carrying away even more heat from the intake air.
The installation of the PPE Heat Exchanger is a breeze – no grille removal required. The stock mounting brackets are retained for a seamless fitment. This unit alone will enhance the performance of the stock air-to-liquid intercooler. However, when paired with the PPE Air-to-Water Intercooler Kit, the combination delivers unmatched cooling performance, increasing charge air density, and transforming your 3.0L Duramax into a powerhouse.

If you have a ZR2 then you know air flow is completely cut off. Out of the box you can see the difference just by looking at the fins. Definitely could tell a difference from first start up after install. I don't have a idash so can't give any data but engine felt like it was running smoother. Could feel the difference sitting in Florida traffic with the heat, it didn't have the lag like it did. Install was simple and straightforward. Would recommend some hose pinchers to save a mess. Would definitely recommend this upgrade.

Upgrading to the PPE heat exchanger paired with the PPE intercooler made a significant difference in cooling and overall efficiency for the truck. This combination noticeably improved operating temperatures and engine performance. Based on the results, this setup is highly recommended for all 3.0L Duramax owners looking to optimize reliability, cooling, and efficiency.

I installed this on Saturday. The installation went smooth, and it fit perfect. I am getting my truck ready to tow this summer and this should definitely help my new PPE intercooler stay cool.
