BMW Maintenance & Tune-Up Parts for BMW 3 Series E46 (1999-2005)

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 cooling system failure parts bundled into a complete package. This cooling system package is for the E46 with the M52/54 engine.  

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 thermostat housing, radiator, and 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 entire cooling system. Keep on top of the cooling needs of your engine for your own piece of mind. Potential buyers also see the upside of a properly maintained car with receipts. 

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 
2001-2002 E46 3 Series Sedan/Wagon - 325i, 325xi, 330i, 330xi 
2001-2002 E46 3 Series Coupe/Convertible - 325Ci, 330Ci 

If you plan to drive your BMW aggressively on the track, it is important that you upgrade your cooling system to avoid overheating. To ensure your BMW keeps cool on the track, we have built out our new High Performance Cooling System Upgrade kits. Featured in this kit is everything you will need to redo your cooling system from top to bottom with OEM components, with select stock components swapped out for the high performance alternative! This kit includes a high performance Mishimoto Radiator, for significantly better cooling than the stock radiator and full aluminum construction that won't crack from long term heat cycling, a performance Mishimoto 70*C thermostat, for lower temperature operation and increased cooling of the engine, and a Stewart High Performance Water Pump, for dramatically increased coolant flow at all RPMs. 

Additional items included in this kit:

• OEM Replacement Coolant Hoses
• OEM Expansion Tank, Cap, and Level Sensor
• OEM Belts, Tensioners, and Pulleys
• OEM Auxiliary Fan Switch
• Genuine BMW Hardware for Easy Installation
• ECS Tuning Aluminum Water Pump Pulley - For increased reliability over the stock composite pulley

The hoses and oil separator can crack or become faulty, leading to vacuum leaks or oil leaks. This is caused by the stress the plastic components are exposed to during heating and cooling cycles, especially if the vehicle is not brought up to operating temperature during driving in cold weather climates.

This kit includes the needed hoses, oil separator, and hardware.

Fits the following BMWs:

Liqui Moly Molygen New Generation fully synthetic engine oil is carefully engineered, starting with a high quality synthetic base. What separates Molygen from other engine oils is the molecular friction modifier for reduced friction and wear. Because of this, Molygen glows fluorescent green under UV light, allowing you to easily find any leaks!

The fluorescent green chemical friction modifier smooths out hard metal surfaces, reducing overall engine wear and heat due to friction. Tests have shown to reduce the friction coefficient by 15%!? MolyGen oil is also a great choice for modern forced induction engines which produce much more heat. BMWs are notorious for leaking oil. Make chasing your leak easier with Liqui Moly Molygen New Generation engine oil. (Once you find it, give us a call - we can help you stop that leak, too!)
