URO BMW Cooling System Parts & Accessories for BMW 3 Series E36 (1992-1998)

Clear BMW chassis

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.

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 peices. Be sure to get a new fan clutch, while you are replacing this.Â

The thermostat on your vehicle controls the flow of coolant based on temperature. When you just start your engine, the thermostat remains closed to accelerate the warm up process. After a few minutes, it opens up to allow the warm fluid to flow. If your vehicle is overheating but not blowing warm air from the heater, the problem is more than likely your thermostat. If the thermostat gets stuck closed, it allows no fluid to flow and ends up overheating the coolant already in the engine. If your vehicle is not getting up to temperature when driving, the thermostat is more than likely stuck open. Your engine does not get up to the proper operating temperature where it runs the most efficiently. To fix this problem and get your vehicle's heat restored, replace your thermostat.

Over the years and with exposure to extremely hot coolant, the coolant hoses in your vehicle can take a beating. Being made of reinforced rubber, these hoses can fail in a number of ways. Splitting at a hose clamp, swelling, cracking, and breaking are just a few of the ways this hose can leave you stranded. Replace it at the first sign of wear to keep your coolant in your engine. With the proper diameter, bends, and lengths, this is the perfect replacement for any swelled or damaged hose. An easy installation, it's piece of mind the next time you are on a long trip or your morning commute.

URO Expansion Tank Cap - BMW E30

The URO Expansion Tank Cap - BMW E30 is a crucial component for maintaining optimal cooling system performance by ensuring proper pressure regulation. Over time, older radiator caps lose their ability to hold pressure, leading to a lower boiling point and potential overheating issues. This high-quality replacement cap is designed to restore factory pressure levels, preventing coolant loss and maintaining engine efficiency. Crafted from durable materials, it resists wear and temperature fluctuations, ensuring long-lasting reliability.

Direct replacement for BMW E30 models
Maintains correct cooling system pressure to prevent overheating
Helps sustain optimal engine temperature and performance
High-quality construction for durability and reliability
Prevents coolant evaporation and system inefficiencies
Easy installation with OE-style fitment
