This performance 82°C thermostat suits Holden Buick LN3 L27, Ecotec L36 and L67 Supercharged 3.8L V6 engines.
- Drops engine temperature by 10°C.
- Prevents overheating and improves performance.
- DIY installation.
- Super-affordable performance modification.
- Up to 30% higher coolant flow in comparison to standard replacement items, due to larger cross sectional area and more stream lined features.
Heat is the single biggest killer of performance and can actually damage your engine if its exposed to extreme temperatures for a extended time frames. Avoiding heat in its various forms will not only help boost your engine's performance but also ensure that power levels are consistent and reliable.
A cheap way to reduce coolant temperatures in these engines is by installing one of our 82°C thermostats.
Factory-supplied thermostats begin to open at 92°C. This is far too high for a performance application. At this temperature, your engine could begin to suffer from pre-ignition (detonation) or at the very least the ECU will retard the ignition timing to prevent detonation, robbing you of precious horsepower.
Our 82°C thermostat opens much earlier than the factory item, allowing coolant to flow through the engine from the radiator much sooner. This limits the peak engine temperature by 10°C, preventing overheating.
With your engine running consistently cooler, your horsepower levels across the rev range will be more consistent and reliable which is especially good for boosted applications or even when towing on hot summer days.
