BMW E46 Radiators & Cooling System Overhaul Kits

BMW E46 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.

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

Aluminum Coolant Bleeder Screw 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.

  • 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.

Our goal was to make this as close to a "drop-in" replacement 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.

Complete Cooling System Overhaul Package - 1999-2006 E46 323i 325i 328i 330i 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

Coolant Expansion Tank - E46 (non-M), X3, X5 3.0 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)

Complete Cooling System Overhaul Package - 2001-2006 E46 M3

As the E46 M3 gets on in years and mileage, the cooling system will be one of the areas that needs the most attention. We have packaged all of the major cooling components into one overhaul kit:

  • radiator
  • water pump
  • thermostat
  • radiator hoses and clamps
  • gaskets and o-rings

We have found that the E46 M3 can develop inconvenient cooling issues, even on daily driven street cars. While the infamous radiator and water pump failures of the E36 are a thing of the past, the E46 M3 still has its own complications. The best approach to avoid bigger problems is preventative maintenance. We recommend replacing the water pump before 80,000 miles and the radiator before 100,000 miles. By addressing these problem areas before a failure, you will save yourself a larger repair bill in the future.

In addition to the standard cooling package items above, there are several other cooling-related components that may make sense to do at the same time:

  • Original BMW coolant
  • fan clutch
  • main serpentine belt and A/C belt
  • Turner Power Pulley Kit (because now is the perfect time!)

This cooling overhaul package fits:

Coolant/Washer Level Sensor (installs in expansion tank) - Many BMW (see list) 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)

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

This fluid level sensor is found on the following BMWs:
