The Mishimoto Thermostatic Oil Cooler Kit is a high-performance cooling solution designed specifically for LS series engines, including the 2004-2006 Pontiac GTO. This kit features a 25-row stacked-plate oil cooler, which provides superior heat dissipation to maintain optimal oil temperatures during demanding driving conditions. Built with durable materials and a thermostatic control, it ensures consistent oil temperature regulation, enhancing engine reliability and performance. The inclusion of a specially designed oil line adapter that bolts to the oil filter housing simplifies installation and ensures a secure fit. This oil cooler kit is engineered to handle the high thermal loads generated by powerful engines, making it an excellent upgrade for enthusiasts seeking improved cooling efficiency and engine longevity.

Designed for 2004-2006 Pontiac GTO models equipped with LS series engines, this thermostatic oil cooler kit is a direct bolt-on upgrade that fits seamlessly into the factory setup. It is suitable for street, track, or high-performance applications where maintaining optimal oil temperature is critical. The kit includes the 25-row stacked-plate cooler, oil line adapter, and all necessary mounting hardware, providing a complete solution for enhanced cooling. Installation involves attaching the cooler to the engine and connecting the oil lines to the existing filter housing, making it a straightforward upgrade for those looking to improve engine cooling capacity and reliability during intense driving or extended track sessions.

Overview

Thermostatic Oil Cooler Kit by Mishimoto

LS series engines are simple, powerful, reliable machines, but no engine can deal with high oil temperatures. To cool the GTO’s massive engine, we picked our largest oil cooler for the job. The 25-row stacked-plate cooler will have no problem making sure oil is at an optimal temperature.

On the other end of this GTO oil cooler kit is a specially designed oil line adapter that bolts to the oil filter housing to allow for the attachment of our –AN stainless steel lines. The tight space restrictions eliminated the possibility of using a thermostatic sandwich plate, which we use on most of our other direct-fit oil cooler kits. Instead our In-line Oil Thermostat is used to regulate oil temperatures. This meticulously designed thermostat mounts under the headlight by means of its own direct-fit bracket, and will make sure your oil stays at a happy 185°F.

During the testing process of this GTO oil cooler, the in-line thermostat was not used in order to eliminate it as a regulating variable. This means oil is constantly flowing through the cooler during testing, and these tests showed a 65°F oil temperature drop. This massive drop shows the cooling capabilities of this GTO oil cooler kit. Just like all of Mishimoto’s GTO parts, this kit comes with the Mishimoto Lifetime Warranty to make sure your oil temperatures are always on point.

Mishimoto recommends that you check all connections at regular intervals, especially during the first few miles after installation.
