BMW Cooling System Parts & Accessories for BMW Z3 (1996-2002)

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.

Our Turner Motorsport's full aluminum expansion tank was designed and engineered in house to help with the weak point in your E36 cooling system. The coolant expansion tank goes through heat cycles over and over again from regular driving, it is important that your expansion tank is doing its job to retain coolant to keep your engine operating temperatures down and keep your engine bay clean. Not only is this a major upgrade but also a great maintenance item to replace. Our expansion tank was designed to fit the OEM hoses for an easy install and comes with all the upgraded items you will need for a clean install,

If your E36 needs a new expansion tank, make sure this is the last expansion tank you ever need to buy. Our coolant expansion tank has a full aluminum construction and wrinkle black powder coat for durability. Expansion tank kit comes with all the accessories you need to replace your expansion tank once, and never have to worry about it again.

Aluminum Coolant Expansion Tank Features:

- Maintains stock coolant capacity and expansion volume

- Designed to maintain OE coolant elevation, preventing air pockets

- Baffled tank ensures that air pockets cannot be introduced during aggressive driving and provides accurate coolant level reading

- Carefully designed bleed passage prevents the introduction of air as the engine cools

- Turner engraved internal fill level

- TIG welded 5052 aluminum construction

- All bungs are machined to fit factory hose ends

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.

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.

ECS Tuning's Aluminum Coolant Bleeder Screw replaces Genuine BMW Part Number 17111712788

Most of the pulleys on your BMW engine are plastic, which become brittle and frail over time and from engine bay heat. A failed pulley could leave you stranded which is why it is vital to inspect the pulleys during routine maintenance. This is an aluminum version of the stock water pump pulley used on the M50/M52/M52TU/M54 engine in the E36, E46, Z3, Z4, and other models. It uses the same hardware and the original belt as the stock plastic pulley. But the aluminum will last much longer.

When it comes to BMW's we all know the weak point is commonly in the cooling system, many models proving hard to bleed the air pockets out after the refresh. The coolant refill tool solves this problem, ensuring that you get an air pocket free fill. The entire task is as simple as draining the system like normal, reinstalling the drain plugs and hooking the tool up to your refill location. The reason this tool works so well is due to the venturi valve, it converts air pressure from the compressor to vacuum inside the cooling system, then with a twist of a valve sucks coolant right into the system using the vacuum pressure.

Every hero has its Achilles heel, and for many BMWs, it's the cooling system. Featuring an overabundance of brittle, crack-prone, leak-inducing plastic, the otherwise robust drivetrain is let down by a weak cooling system. Now, ECS has come to the rescue with a solution to cure those problems once and for all and leave the days of cracked plastic end tanks and coolant-stained driveways far behind. This radiator was designed with performance, durability, and good looks in mind to create a great all-around upgrade for any E36 owner, from the daily driver to the weekend warrior. Featuring fully aluminum construction, all the joints are precision TIG-welded for superior durability and show-car looks, with polished end tanks further adding to the great look of this radiator. The easily-stripped plastic drain plug and fan switch holes have been replaced with threaded alloy bungs in the stock locations, and the weak plastic tabs for the factory fan shroud have been replaced with beefy aluminum as well. Designed as a drop-in solution, this radiator will fit like a stock replacement, but will look and perform far better, while costing substantially less than the competition. What are you waiting for? Upgrade your cooling system today and leave your worries behind - and look great doing it - with this ECS Tuning Performance Aluminum Radiator. Note: Owners of automatic E36s utilizing a stock-style transmission cooler must drill two small holes in the lower frame of the radiator.

Over time, clamps can deform or lose their tightness due to aging or frequent removal, potentially causing leaks in your coolant or vacuum hoses. Avoid the risk of leaks by replacing old clamps with new hardware, offering peace of mind against coolant and vacuum system issues.

Key benefits of the adjustable hose clamp include:

  • Maintaining a secure and leak-free seal in your BMW's systems.
  • Preventing coolant or vacuum leaks that can affect performance.
  • Adjustable size from 70mm to 78mm for versatile applications.

Upgrade your hose clamps to ensure optimal performance and reliability in your BMW's systems.

With less than 1 1/2" clearance on some models this project can easily turn into a mechanical nightmare. Using our special slim line fan clutch wrench in conjunction with the appropriate pulley spanner, the removal and installation required only a few moments.

This radiator expansion tank is used on E53 X5 4.4i and 4.6is with M62 engine, and Z3 2.3 2.5i 2.8 3.0i from 1999-2002. It is a common failure item as the plastic weakens over time and stress cracks will lead to coolant leaks. 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. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

This is the coolant temperature sensor used in many BMW models from the mid-1990s to the mid-2000s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future.

This fan is driven by the serpentine belt, engaged by the fan clutch. If you have bad motor mounts, it's quite common for the blades of this fan to make contact with the radiator or radiator shroud, essentially self-destructing the fan into many pieces. Be sure to get a new fan clutch, while you are replacing this.
