Please ensure your correct model is selected

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

The BMW E30 / E36 / E46 Offset Lower Radiator Mounts are designed to provide enhanced support and positioning for the radiator in BMW models, specifically the E30, E36, and E46. These mounts are a practical upgrade for vehicles that require extra clearance, especially when using aftermarket or larger radiators in performance builds.

Key Features:

  1. Offset Design for Increased Clearance:

    • The offset configuration of these mounts offers additional room, making them ideal for accommodating larger radiators or custom cooling setups. This ensures proper fitment, especially in high-performance or modified vehicles.
  2. Stable and Secure Mounting:

    • These mounts provide firm support to keep the radiator securely in place, preventing unwanted movement or vibration, which is crucial for maintaining the cooling system’s efficiency during intense driving conditions.
  3. Durability and Heat Resistance:

    • Built from high-quality, heat-resistant materials, these mounts are designed to withstand the rigors of both daily driving and track use. They ensure long-lasting performance even under high temperatures and stress.
  4. Optimized Cooling Performance:

    • By ensuring the radiator is properly aligned and secured, these mounts help maximize the cooling system's performance. Proper positioning allows for efficient airflow through the radiator, which is vital for preventing overheating during demanding driving situations.
  5. Easy Installation:

    • These offset radiator mounts are designed as a direct-fit replacement, making installation simple and straightforward. They are compatible with the BMW E30, E36, and E46, allowing for an easy upgrade to support larger or performance-focused radiators.
  6. Perfect for Modified and Performance Builds:

    • Whether you're upgrading to a high-capacity radiator or modifying your vehicle for improved performance, these mounts offer the extra flexibility and stability needed for customized setups.

Benefits of Upgrading or Replacing:

  • Extra Clearance for Larger Radiators: The offset design allows for better fitment, especially when upgrading to a larger or aftermarket radiator.
  • Prevents Vibration and Damage: These mounts reduce the risk of damage caused by vibration or radiator movement, ensuring longer-lasting performance.
  • Enhanced Cooling Efficiency: Properly securing the radiator ensures that it can work at peak efficiency, leading to better cooling performance during high-demand driving.

In summary, the BMW E30 / E36 / E46 Offset Lower Radiator Mounts are an excellent choice for enthusiasts looking to upgrade their cooling system or accommodate a larger radiator. Their durable construction, ease of installation, and offset design make them a valuable addition for performance builds or maintaining cooling system reliability in modified BMWs.
