BMW Cooling System Parts & Accessories for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

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 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 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.

These high quality silicone hoses feature stock-type quick-disconnect fittings - no need to cut up your old hoses to get the connectors off! Unlike factory rubber hoses, silicone can withstand higher temperatures and pressures with minmal wear. Rubber will wear out and weaken so don't let it bite you when it counts! Silicone has been proven during extreme racing conditions and won't be the weak link that ruins your day.

The pre-attached stock-style plastic quick-disconnect fittings include new O-rings, providing a reliable leak-free seal during installation. We do not recommend re-using the temp sensor located in the lower radiator hose. You can add a new one to your order from the options below.

Mishimoto E46 Aluminum Radiator features -

  • All aluminum construction
  • More durable and longer lasting than plastic components
  • 20% 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 E46 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.

Radiators for manual and automatic transmissions are different. Choose the one correct for your model from the options below.

This electric fan for the E46 M3 takes the place of the stock engine-mounted fan and offers several advantages - more horsepower by removing parasitic drag customizable temp control (with optional fan controller - not included in this kit) frame included for a direct fit more reliable than a stock-style fan clutch The stock engine fan is mounted on the water pump shaft and spins with the engine. Torque from the engine is used to spin the fan, which could otherwise be used to power the car. It's not a lot of lost power and torque - Mishimoto measured a max gain of 5whp - but sometimes every little bit helps. And the other advantages of an electric fan make it a smart move. The Mishimoto electric fan uses a 16" slim profile electric fan that flows at 1,850 cubic feet per minute (CFM). The shroud and frame are black powedercoated steel and mounts to existing points on the radiator for a seamless install. Mishimoto has confirmed fitment with stock radiators as well as their own Performance and X-Line aluminum radiators. Hardware and instructions are included. An electric fan must be powered by a 12v source. A fan controller kit is optional and is activated by coolant temp. This is the preferred setup method but other types of controls may also be used. Looking for a kit that includes the fan controller and temp sensors? See T#637722

  • more horsepower by removing parasitic drag
  • customizable temp control (with optional fan controller)
  • frame included for a direct fit
  • more reliable than a stock-style fan clutch

The stock engine fan is mounted on the water pump shaft and spins with the engine. Torque from the engine is used to spin the fan, which could otherwise be used to power the car. It's not a lot of lost power and torque - Mishimoto measured a max gain of 6whp - but sometimes every little bit helps. And the other advantages of an electric fan make it a smart move.

The Mishimoto electric fan uses a 16" slim profile electric fan that flows at 1,850 cubic feet per minute (CFM). The shroud and frame are black powedercoated steel and mounts to existing points on the radiator for a seemless install. Mishimoto has confirmed fitment with stock radiators as well as their own Performance and X-Line aluminum radiators. Hardware and instructions are included.

An electric fan must be powered by a 12v source. A fan controller kit is optional and is activated by coolant temp. This is the preferred setup method but other types of controls may also be used. There are two styles of Mishimoto fan controllers - a sensor located in a 1/8" NPT plug or as a 6" probe inserted between the fins on the radiator. For BMW applications, the NPT plug is usually the best and Mishimoto has this port built into their radiator designs (most other aluminum radiators do as well). For the E46, Mishimoto has a dedicated wiring harness with the optional controller that takes power from the factory fuse panel.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. Ideal for the SE46 racing series, the AAF E46 6-speed Transmission Crossmember is a heavy-duty and worthwhile upgrade. The OEM thin cast aluminum cross member has been known to fail in multiple different ways. When using stiff engine and transmission mounts, the cross member can crack out and break around these mounting points. The cross member can also break from the high amounts of load transferred through the drive train. While chassis flex from hard cornering is being applied through the engine and transmission from the front cross member, this load is sent from the transmission back into the chassis at the transmission cross member. This is simply too much stress for the OEM cross member to hold up to under the extreme punishment of road racing. The AAF E46 Transmission Cross Member is completely constructed of 1/4' thick heavy-duty aluminum plate. It is designed specifically to cope with hours of endurance racing.

More than likely, you are going to replace the radiator in your vehicle at least once. The joints where the cores meet the end tanks tend to get weak and are the first place to spring a leak. Impacts to the fins themselves can cause holes to form. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow. Replace your leaking unit with a factory replacement and get that jug of coolant out of your back seat. This is a factory original style radiator from Genuine BMW and will fit perfectly into the stock location. Cooling will be identical to what your car came with originally. A great replacement with all the proper connections and in all of the proper locations. When doing radiator and cooling service, you will obviously lose coolant. Browse through the cooling section of your model to see factory correct coolants, seals, and caps. Before beginning, check your hoses to make sure everything is in good shape.
