* Type of Oil Cooler: There are several types, including air-cooled (mounted in front of the radiator) and liquid-cooled (integrated into the radiator or using a separate coolant loop). Air-cooled is generally simpler to install.
* Mounting Location: This depends on your vehicle and the type of oil cooler chosen. Common locations include in front of the radiator (for air-cooled), in the radiator (for liquid-cooled), or even remotely mounted with custom lines.
* Oil Lines & Fittings: You'll need to run new oil lines from the engine block (typically tapping into the oil filter adapter or a dedicated oil cooler port if available) to the oil cooler and back to the engine. This requires careful selection of fittings and hoses compatible with your system's oil pressure and temperature.
* Thermostatic Valve (Recommended): A thermostatic valve is highly recommended. This valve allows oil to bypass the cooler until it reaches a specific operating temperature, preventing the oil from becoming too cold, especially during cold starts. This protects engine components from cold start wear.
* Plumbing & Installation: This involves routing the lines, securing the cooler, and ensuring proper clearances to avoid interference with other components. This may require some fabrication or modification.
* Cooling System Capacity (If Liquid-Cooled): Liquid-cooled systems increase the overall coolant volume, so ensure your radiator and coolant system can handle the increased capacity.
In short, while it's feasible, fitting an oil cooler to a Chevy 350 isn't a straightforward DIY project for beginners. It's advisable to have some mechanical experience or seek professional help for proper installation to avoid potential damage to the engine. The complexity and cost will vary based on the chosen cooler type and installation method.
