Product Details

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 1999-2000 528i with the M52TU engine and the 2001-2003 525i and 530i with the M54 engine. This package applies to cars equipped with either the manual or automatic transmission.

Much of the later E39 cooling system is strong and reliable and doesn't suffer the same types of problems associated with earlier E39 and E36 systems. But there is still the potential for serious cooling system and engine-related failures. Several of the primary cooling components are prone to failure within 80k miles (or less in many cases). 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. Our kit includes an OEM Behr radiator, an Original BMW water pump (with updated composite impeller), thermostat with housing, radiator cap, and new radiator hoses.

Optional items (which can be added below):
- Original BMW antifreeze
- Upgrade the water pump to a Stewart EMP High Performance pump
- Add a new coolant expansion tank (known for cracking)
- Add a new coolant level sensor (known for failing / throwing "check coolant" messages)
- Add a new coolant temp sensor (located in lower radiator hose and the seal ring may cause leaks if re-used)

This cooling system overhaul kit fits the following BMWs:
1999-2003 E39 BMW 525i 528i 530i
