This coolant reservoir is for the non-M E46 3-series models from 1999-2006 (M3 takes a different expansion tank). We have found that the expansion tanks should be replaced based on age as well as condition. Expansion tanks seem to have a lifespan of less than six years before they show signs of fatigue and wear. Pre-emptively replacing the expansion tank as part of an overall maintenance plan can prevent you from getting stranded from a sudden failure later on. This is the most recent expansion tank design from Hella-Behr, the OEM supplier to BMW. It replaces the original BMW part number 17137787039.

Other items to consider replacing at the same time are the radiator cap, coolant level sensor, lower radiator hose, coolant temp sensor in the lower hose, and the hose clamps. If your car has an automatic transmission you should also replace the oil cooler thermostat in the radiator frame, which is a common source for leaks.

This coolant expansion tank fits:

1999-2006 E46 3 series - 323i, 323Ci, 325i, 325Ci, 325xi, 328i, 328Ci, 330i, 330Ci & 330xi (**no M)

This clutch engages the belt-driven engine fan when the engine is warm/hot, and dis-engages the fan when cold/cool. These commonly fail, causing the engine fan to not spin fast enough (or at all) when your car is stopped in traffic, causing engine to overheat.

This Original BMW water pump is the latest updated design with a composite impeller. The composite material (similar to Kevlar) is much stronger than the problematic plastic impeller from past water pumps. And it's lighter than the aftermarket metal impellers so that means less strain on the bearing. For an OE/OEM replacement, we have found that this is the highest quality and longest lasting waterpump available.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This waterpump fits the following BMWs:
1999-2006 E46 3 series - 323i, 323Ci, 328i, 328Ci, 325i, 325Ci, 330i, 330Ci

    • 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.

Replacing the fan clutch on most BMW models requires holding the water pump pulley while removing the fan clutch lock nut. With less than 1 1/2" clearance on some models this project can easily turn into a mechanical nightmare. Using our special slim line fan clutch wrench in conjunction with the appropriate pulley spanner, the removal and installation required only a few moments.

The auxiliary fan in your vehicle serves an extremely important role. When your car reaches temperatures that may be hazardous to your engine, the auxiliary fan moves air through the radiator to provide better cooling. Usually activated during times of stationary vehicle operation, it supplements the air usually driven through the radiator by driving down the road. If your vehicle is getting too hot during traffic or at stop lights, your auxiliary fans are probably faulty. Replace yours with this piece from ACM to restore the factory cooling in your vehicle and prevent catastrophic damage to your engine. Even if your fans are still operational but the blades are damaged or cracked, replacement is the only solution.

Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

See kit contents below for all included components.

This is a compete cooling system overhaul kit, which includes all the common E46 cooling system failure parts bundled into a complete package. This cooling system package is for all of the non-M E46 3 series -- those made in 1999-2005 as well as 2006 coupes and convertibles.

The E46 cooling system is much like that of the previous generation 3 series. Several of the primary cooling components are prone to failure within 60k miles (or less in many cases). A failure in the cooling system can lead to overheating and catastrophic engine failure. Don't gamble your engine! By replacing these core items preventatively, such as the radiator & waterpump, you are defusing what could be a ticking cooling system time bomb. And if you've had a failure of one of these parts, now is the time to refresh your cooling system. Our kit includes one OEM Behr radiator, an Original BMW water pump (with updated composite impeller), thermostat (complete with housing), radiator cap, and new hoses (as pictured).

Optional items (which can be added below):
- Original BMW antifreeze
- Upgrade the water pump to a Stewart EMP High Performance pump
- Add a new coolant expansion tank (known for cracking)
- Add a new coolant level sensor (known for failing / throwing "check coolant" messages)

This cooling system overhaul kit fits the following BMWs:
1999-2000 E46 3 Series Sedan/Wagon - 323i & 328i
1999-2000 E46 3 Series Coupe/Convertible - 323Ci & 328Ci
2001-2005 E46 3 Series Sedan/Wagon - 325i, 325xi, 330i, 330xi
2001-2006 E46 3 Series Coupe/Convertible - 325Ci, 330Ci
