BMW Radiators & Cooling System Overhaul Kits

We sell only OEM Behr, Original BMW, or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used too many weak materials like plastic for critical connections. The core and sizing of the radiators are generally sufficient for the intended application but problems can occur at hose connections, upper or lower necks, and plastic end tanks. The radiators we sell are all OEM designs to keep the quality high. In some cases the OEM has made design improvements to prevent past issues. There are a number of non-OEM replacement radiators that use even cheaper materials and poor workmanship which only leads to more problems. On some models we offer OEM alternatives that perform as upgrades to the original designs and we also offer full race all-aluminum radiator upgrades that solve all of the issues with plastic radiators.

Replace the flimsy plastic bleeder screw used in the coolant expansion tank or in one of the cooling system hoses with this high quality, durable, aluminum bleeder screw. The stock plastic screw can deform over time due to heat or even regular use. We have even seen the head of the screw snap off, leaving the threaded body stuck in the expansion tank. This aluminum screw will help to prevent sudden failure of the bleeder screw, which can result in immediate overheating of the car.

+25% capacity

  • Triple-row core (vs double row)
  • Better cooling without increasing overall dimensions
  • All-aluminum construction

This is the new E46 M3 aluminum radiator that we collaborated with FLUIDYNE on. We're taking advantage of FLUIDYNE's new core design that packs much more surface area in a stock-sized core. Instead of the usual two rows of tubes, FLUIDYNE's all-aluminum radiator has three rows of tubes in a core no thicker than the stock radiator. This radiator also has 30% more rows than the stock radiator (55 vs 42). With greater surface area and more efficient use of air flow comes better cooling, especially in the most critical spot where the fins meet the tubes, as this is where most of the heat transfer happens. Where most other aluminum radiators use a thicker core, FLUIDYNE's new packaging solution performs better and fits better in the engine bay with better clearance to other components. A second benefit with this new core is that it minimizes added weight gain, helping to get the car as light - and as fast - as possible.

FLUIDYNE made this easy as this core is no larger than the stock radiator even though it has more capacity. We also had hangers designed to accommodate the factory oil cooler and fan shroud. There has never been a better E46 M3 radiator upgrade than this! For an E46 M3 track or modded street car there should be no reason to ever go back to a stock plastic radiator or compromise on a cheap aluminum radiator. The latest FLUIDYNE is the best there is.

The stock radiator has an aluminum core but with plastic end-tanks and hose connections that become brittle and can leak or crack. You may not even realize your radiator neck is cracked until it's too late and you're stranded on the side of the freeway or unable to continue with your track day. An all-aluminum design does not suffer the defects of similar plastic construction. FLUIDYNE quality is what sets them apart from every other manufacturer. Their radiators feature a high-tech CAB-brazed core construction instead of epoxy (which can leak). All tanks and brackets are TIG welded by hand in the USA. If you plan on owning your BMW for many years to come, or are using it in a situation where failure is NOT an option such as track or racing, then this should be your only option instead of the failure-prone stock radiators.

Some modifications may be needed to to fit this radiator.

This is the sensor / sending unit that notifies the computer if your coolant level is low. When this fails, it can give a false indication of low coolant -- or worse, not inform you of a low coolant situation which could potential cause overheating. (Note: This sensor is also found in the windshield washer container, to alert the computer when you are low on washer fluid)

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 sensor also serves as the washer fluid level sensor on many models.

This fluid level sensor is found on the following BMWs:

    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)

    Mishimoto E36 Aluminum Radiator features -

    • All aluminum construction
    • More durable and longer lasting than plastic components
    • 30% more capacity in the same space
    • Excellent fit and finish
    • Unbeatable lifetime warranty and accident-forgiveness

    Mishimoto radiators address all of the defects of the stock E36 radiator in a well-engineered and price-competitive direct replacement unit. The Mishimoto radiator is an all aluminum design that replaces the factory plastic and aluminum stock radiator. The stock plastic end tanks are notorious for cracking and leaks whereas the Mishimoto has aluminum end tanks that will never fail. Mishimoto can also build 30% more coolant capacity into the a radiator that fits in the original location with no modifications. More coolant volume means the fluid is not heat soaked for as long (less super heated fluid circulating through the engine). For a direct replacement performance radiator, the Mishimoto is hard to beat!

    Mishimoto was established in 2003 as a supplier of cooling components for drift and rally cars. Their radiators and intercoolers soon found a strong following in the hyper competitive drift scene where high horsepower and prolonged high revs dictate the need for durable and robust cooling solutions. The catchy Mishimoto name is a combination of the name of the founder's family pet - Mishi - and "moto". All products are designed and tested in the USA using state-of-the-art CAD tools and prototyping and with continuous evolution of product design. Mishimoto is so dedicated to quality that they offer a limited lifetime warranty and accident forgiveness.

Paired with these radiators are CNC machined brackets and corrosion resistant hardware that allow final installation to have a same as stock fitment! This enables you to have much higher cooling without having to cut away any metal or delete any important components just for the sake of lower coolant temperatures.

    Features:

    • Two-row, triple-pass design radiator core
    • CNC machined mounting brackets
    • All needed hardware included
    • Hand polished aluminum with a mirror-like finish
    • Stock fitment prevents modification to engine bay

    If you have ever experienced a leaking plastic BMW expansion tank you will realize the value of this aluminum version straight away. Even if a failure has not happened to you, it's easy to tell this tank is much stronger and more durable than the plastic used in the stock design. Mishimoto has extended their cooling system expertise from aluminum radiators to expansion tank design. The original BMW plastic tanks suffer from leaks and failures with no warning. While being light weight and recyclable the design and construction of the stock tank is just not up for reliable long term use. Mishimoto has designed their tank with an integrated dipstick/bleeder and a 1.3bar cap that raises the boiling point of the system (the stock radiator cap is not compatible).

    The Mishimoto expansion tank takes the place of the stock tank in the stock plastic radiator fan shroud or in the Mishimoto electric fan and shroud upgrade. It takes the stock coolant level sensor and the upper and lower hoses as well.

    Lifetime warranty!
