When it comes to keeping your Small Block Chevy (SBC) engine running strong, a high-performance oil cooler kit is a game-changer. Engine oil not only lubricates internal components, but it also dissipates heat. When the oil overheats, it can break down, leading to premature wear, poor engine performance, or even catastrophic failure.
That’s where an SBC engine oil cooler kit steps in, it’s designed to maintain optimal oil temperature, especially during high RPMs or hot climates. This post explores what oil cooler kits do, their benefits, and seven top kits that can keep your engine cool under pressure.

What is an SBC Engine Oil Cooler Kit?
An SBC engine oil cooler kit is an aftermarket setup that cools your engine oil as it circulates through a heat exchanger, often placed in front of the radiator. It’s especially beneficial for performance cars, trucks, hot rods, or classic Chevys using SBC engines under high load or extreme conditions.
Why is an Oil Cooler Important for Your Small Block Chevy (SBC)?
Small Block Chevys are legendary for their versatility and performance, but they also generate substantial heat. Prolonged heat exposure degrades oil, causing it to lose its viscosity and protective properties. An oil cooler:
- Increases oil life
- Maintains consistent engine performance
- Prevents overheating during towing or racing
- Reduces internal engine wear

Key Components of a High-Quality Oil Cooler Kit
Oil Cooler Core
The heart of the system uses aluminum fins and passages to dissipate heat as oil flows through.
Hoses and Fittings
Most kits include braided stainless steel or rubber hoses with AN fittings for leak-proof performance.
Oil Sandwich Adapter
This component routes oil through the cooler before returning it to the engine. Some have built-in thermostats for smart temperature control.
Benefits of Using an SBC Engine Oil Cooler Kit
- Improved Engine Longevity: Keeps temperatures within a safe range.
- Increased Performance: Stable temperatures mean better efficiency.
- Better Lubrication: Maintains oil viscosity under extreme conditions.
- Fuel Efficiency: Reduces drag from overheated, degraded oil.
- Protects Turbochargers (if installed): Prevents oil coking in high-heat areas.

How to Choose the Right Oil Cooler Kit for Your SBC
When shopping for a kit, consider:
- Engine size and application (street, race, tow)
- Row count and size of the cooler
- Hose length and quality
- Adapter Compatibility
- Ease of installation
Installation Guide: Installing Your SBC Oil Cooler Kit
Installation varies, but most setups follow these steps:
- Mount the Cooler: Choose a location with ample airflow (usually front of the radiator).
- Attach Hoses: Run hoses from the sandwich adapter to the cooler.
- Secure Adapter: Replace the oil filter with the sandwich plate and reinstall the filter.
- Check for Leaks: Start the engine and inspect all fittings and lines.
Tip: Use Teflon tape on fittings and always pre-fill the oil cooler to avoid dry starts.

FAQs
Are engine oil coolers worth it?
Yes, engine oil coolers are absolutely worth it, especially for vehicles exposed to high loads, racing, towing, or hot climates. By keeping engine oil temperatures in check, they extend oil life, maintain viscosity, and reduce engine wear. For performance and long-term durability, they’re a smart investment.
Does oil cooler improve performance?
Yes, indirectly. While an oil cooler doesn’t add horsepower, it helps the engine run more efficiently by:
- Maintaining optimal oil viscosity
- Preventing overheating during intense operation
- Reducing internal friction
- This results in smoother performance, more consistent power delivery, and better throttle response under stress.
What are signs of a failing oil cooler?
A failing oil cooler can show several warning signs:
- Oil or coolant leaks around the cooler or hoses
- Rising engine oil temperatures or overheating
- Milky oil (oil mixed with coolant)
- Reduced oil pressure
- Visible damage to the cooler or fittings
Address these issues quickly to avoid major engine damage.
What does an oil cooler kit do?
An oil cooler kit reduces engine oil temperature by circulating the oil through an external cooler mounted in an airflow path (often in front of the radiator). It typically includes:
- A cooling core
- Hoses and fittings
- A sandwich adapter or remote filter mount
The kit helps maintain a stable oil temperature, which improves engine protection and performance.
What is the benefit of an oil cooler on a motorcycle?
Motorcycles, especially air-cooled or high-performance models, benefit from oil coolers by:
- Preventing overheating in traffic or hot weather
- Extending engine life
- Improving oil performance and reducing wear
- Maintaining consistent performance at high RPMs
It’s especially important for bikes used in racing or long-distance touring.
How do I know if my oil cooler is bad or the head gasket?
Both can cause oil and coolant mixing, but here’s how to tell the difference:
A compression test or coolant system pressure test can help confirm a head gasket issue.
What can damage an oil cooler?
Several factors can lead to oil cooler failure:
- Corrosion, especially from road salts or coolant contamination
- Physical impact, such as debris or off-road damage
- Poor installation, leading to hose leaks or broken fittings
- Thermal stress, from repeated overheating cycles
- Blocked internal passages, due to dirty oil or sludge buildup
Regular maintenance and quality parts can prevent most failures.
How long does an engine oil cooler last?
An engine oil cooler can last 5 to 10 years or even longer, depending on:
- Usage conditions
- Maintenance habits
- Quality of the cooler and installation
High-quality aluminum coolers with stainless-steel fittings tend to last the longest. Inspect regularly for leaks or cracks.
