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

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:
    1999-2005 E46 3 Series - 323i, 323Ci, 328i, 328Ci, 325i, 325ix, 325Ci, 330i, 330ix, 330Ci

    Cooling System Overhaul Package for E46 M3   (more info)
    10% Off this month for your BMWAs 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, including: OEM radiator, OE BMW water pump, OEM thermostat, hoses, gaskets, o-rings, and clamps.

    We have found that the E46 M3 can develop serious 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 thing you can do 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.

    We also offer several other items that may help your overhaul project or make sense to do at the same time:
    - Original BMW coolant
    - OEM fan clutch
    - main serpentine belt and A/C belt
    - TMS Power Pulley Kit (now is the perfect time...)

    Applications:
    2001-2006 E46 M3 coupe, cabrio

    E46 Cooling System Overhaul Kit - 1999-2005 3 Series   (more info)
    10% Off this month for your BMWThis 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 difusing 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 waterpump (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 waterpump to a Steward 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

    PWR E46 M3 Aluminum Radiator - M3 2001-2006   (more info)
    The PWR all aluminum radiator is known throughout the world for its superior cooling capabilities. PWR products and technology are used in a multitude of racing classes ranging from F1, BTCC, WRC, Grand-Am, SCCA, Australian V8 Supercars, and NASCAR. Turner Motorsport uses PWR components in our E46 M3, E92 M3, and M3 GT racecars. PWR’s cutting edge design utilizes aircraft-grade aluminum and an oven brazed bonding technology to assure trouble free and reliable cooling even in the harshest conditions. Other radiators use a standard epoxy-seal assembly which can eventually become fatigued and crack due to constant heat cycling and vibration. The PWR radiators used in our own racecars offer an additional 25% cooling capacity, direct bolt-on fitment for E46 M3 (no modifications required to front core support) and precision-machined and TIG-welded end tanks. Each radiator is pressure-tested during manufacturing. The PWR radiator for the E46 M3 proved to be a vital component to the TMS Racing effort and can easily carry over to your race car or street car for years of reliability.

    This item fits the following BMWs:
