When DIY Meets Reliability: Our Experience with the A-Premium Engine Coolant Thermostat housing
As veteran Mini Cooper enthusiasts with our own repair shop, we’ve seen our fair share of thermostat housing failures across the 2011-2016 models. When the familiar symptoms appeared in our customer’s 2014 Cooper Countryman-fluctuating temperature gauge, coolant leaks, and that unmistakable sweet smell of coolant-we decided to try the A-Premium Thermostat Housing Assembly rather of the pricier OEM option.
We’ll be honest: initially, we were skeptical about aftermarket parts for Mini’s notoriously finicky cooling system. Opening the package, however, revealed impressive attention to detail-the housing came complete with all sensors, gaskets, O-rings, and the thermostat itself calibrated to the proper 221°F opening temperature.The three mounting holes aligned perfectly with the engine block without any modification.
What truly impressed us during installation was the quality of the materials. Unlike other aftermarket options we’ve tried, the A-Premium housing features robust construction that feels substantially similar to the OEM part (11537647305) it replaces. The pre-installed sensors eliminated the headache of transferring components from the old housing.
Throughout this review, we’ll break down exactly how this thermostat housing assembly performed across multiple Mini Cooper variants, where it excels, where it falls short, and whether it truly delivers on its promise of OEM-comparable reliability at a fraction of the dealer price…

Comprehensive Installation and Compatibility Guide
##
Installing the A-Premium Engine Coolant thermostat Housing Assembly is remarkably straightforward for DIY enthusiasts with basic mechanical knowledge. We found that the precisely engineered mounting holes align perfectly with the factory specifications for Mini Cooper models (2011-2016), Countryman (2011-2017), and Paceman (2013-2016) with the 1.6L engine. The package includes everything needed for a complete replacement – from the housing unit itself to the thermostat rated at 221°F, necessary sensors, gasket, and O-ring.For 2011-2012 Countryman owners, it’s worth noting that an adapter may be required for specific engine codes (N18B16A and N18 designation), so we recommend verifying your engine code before installation.
Compatibility across different Mini Cooper variants is impressive, with specific engineering for various engine codes including N18B16A, N16B16A, N18B16C, and N18B16M0. Before beginning installation, we suggest draining the cooling system wholly and having a container ready to catch residual coolant. The three mounting points provide secure attachment,while the single outlet port maintains proper coolant flow. Installation typically takes 45-60 minutes depending on skill level, and the complete assembly eliminates the frustration of purchasing components separately. Check Your Mini’s Compatibility Now

## Balanced Analysis
Our testing aligns with the initial positive experiences reported by customers. The A-Premium thermostat housing indeed provides perfect fitment and straightforward installation, representing a cost-effective alternative to the OEM part. The material quality appears satisfactory upon inspection and installation.
However, the customer report of failure after approximately one year (6,000-8,000 km of driving) raises important considerations about long-term reliability. This feedback suggests that while the part functions well initially, some units may not match the longevity of genuine Mini Cooper components.
It’s worth noting that cooling system components in Mini Coopers operate under significant stress, particularly in the 1.6L turbocharged engines these vehicles employ. The temperature cycling and pressure fluctuations in the cooling system create demanding conditions for any replacement part.
## real-World Consensus
Based on customer experiences, the A-Premium thermostat housing assembly represents a viable replacement option with excellent fitment and initial performance. Most users report satisfaction in the short term,with the housing performing its intended function without leaks or issues.
However, prospective buyers should weigh the potential for earlier replacement intervals compared to OEM parts. For those seeking absolute longevity, the dealer-supplied original equipment might prove more economical in the long run despite higher initial costs. For those agreeable with occasional replacements at a lower per-unit cost, the A-Premium offers good value, particularly for older Mini Cooper models past warranty.We recommend considering your specific driving conditions, expected ownership timeline, and comfort with potential future replacement when deciding if this part is right for your Mini Cooper.
