If your vehicle is struggling with cooling problems, the culprit could be the thermostat. Look out for signs like prolonged warm-up periods at highway speeds (indicative of a stuck-open thermostat) or consistent overheating (a sign of a stuck-closed thermostat). These issues can lead to performance issues and potential damage to crucial vehicle parts.

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 the hose that runs from the left radiator to the water valve. Over time, coolant hoses begin to get brittle and are susceptible to cracking and splitting. Replace your cracked or leaking coolant hose to prevent further leaks and potentially catastrophic failure.
This item fits the following BMWs:
1999-2001 E38 BMW 740i 740il
More than likely, you are going to replace the radiator in your vehicle at least once. The joints where the cores meet the end tanks tend to get weak and are the first place to spring a leak. Impacts to the fins themselves can cause holes to form. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow. Replace your leaking unit with a factory replacement and get that jug of coolant out of your back seat.
This is a factory original style radiator from Behr and will fit perfectly into the stock location. Cooling will be identical to what your car came with originally. A great replacement with all the proper connections and in all of the proper locations.
When doing radiator and cooling service, you will obviously lose coolant. Browse through the cooling section of your model to see factory correct coolants, seals, and caps. Before beginning, check your hoses to make sure everything is in good shape.
Maintaining your BMW's cooling system is crucial, especially since the water pump is a well-known weak point. Replacing the thermostat at the same time can help maintain optimal cooling system functionality.
