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 E36 318i/is/ic with the M44 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. 

Don't let an accessory belt failure leave you stranded! Over time, the tensioner and belt wear out, risking your alternator's ability to charge and your vehicle's overall reliability. Turner Motorsport has assembled a comprehensive belt drive service kit to keep everything in check and ensure smooth operation.

Key Benefits:

Complete Service Kit: Includes all necessary components to maintain your belt drive system. Enhanced Reliability: Prevents unexpected belt failures and keeps your vehicle running smoothly. Optimized Performance: Ensures your alternator and A/C system function efficiently. Kit Contents:

Due to weak rubber and plastic construction, vital cooling system parts are prone to premature failure. Key components, such as radiator hoses, the thermostat, and the expansion tank are particularly prone to cracks, leaks, and catastrophic failure, which can lead to overheating and potentially severe engine damage. Fortunately, our team of experts has assembled this kit of high-performance alternatives and high-quality OE replacement components, both tailored to safeguard your cooling system from failure and increase cooling system capability.

The Turner Motorsport Level 1 Performance Cooling System Refresh Kit is the ultimate solution for ensuring long-term reliability and enhanced cooling performance. Each component in this comprehensive kit has been carefully selected by our team of enthusiasts to address common failure points and provide a robust, performance-oriented upgrade for your vehicle. By replacing aging factory parts with premium, high-performance alternatives, you’ll optimize cooling efficiency and safeguard your engine from the stress of overheating.

Our comprehensive "Level 1" High-Performance Cooling System Service Kit includes:

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.

Is your BMW making a chirping or grinding noise at idle? The culprit is frequently a failing alternator decoupler pulley. Unlike a traditional solid pulley, this Overrunning Alternator Pulley (OAP) allows the alternator rotor to "freewheel" when engine speeds drop suddenly. This specialized function protects your BMW drive belt and belt tensioner from excessive snap-back, vibration, and "belt slap."

Prevent Catastrophic Engine Failure

Over time, the internal clutch mechanism can seize or slip, leading to accelerated wear or total serpentine belt failure. On BMW engines, a snapped belt can be ingested through the front main seal, causing catastrophic engine damage. Replacing this pulley is a cost-effective preventative maintenance step that restores smoothness to your accessory drive without the high cost of a complete alternator replacement.

Features & Benefits:

Lowers the load on the drive belt, tensioner, and AC compressor.
Stops "belt slap" and rhythmic chirping noises during deceleration and idle.
Direct Replacement with high-quality construction ensures perfect fitment and long-term durability.
Essential Maintenance for N52 engines

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This filter fits A5S325Z automatic transmissions on BMW E46 323i 323ci 325i 325ci 328i 328ci 330i 330ci . E39 525i 528i 530i. E85 Z4 2.5i Z4 3.0i. This kit includes the transmission filter and gasket.

Kit Contents:

• 1 x 24341423376 - transmission filter
• 1 x 24101423380 - gasket for transmission filter
