    BMW E38 Radiators & Cooling System Overhaul Kits

    We sell only OEM Behr, Original BMW, or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used too many weak materials like plastic for critical connections. The core and sizing of the radiators are generally sufficient for the intended application but problems can occur at hose connections, upper or lower necks, and plastic end tanks. The radiators we sell are all OEM designs to keep the quality high. In some cases the OEM has made design improvements to prevent past issues. There are a number of non-OEM replacement radiators that use even cheaper materials and poor workmanship which only leads to more problems. On some models we offer OEM alternatives that perform as upgrades to the original designs and we also offer full race all-aluminum radiator upgrades that solve all of the issues with plastic radiators.
    You're currently viewing parts for your (E38) 7-Series 1995-2001. Reset your chassis
    For accurate results, specify your year and model below.
    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 1999-2003 540i with the M62TU VAN0S 4.4-liter engine. This package applies to cars equipped with either the manual or automatic transmission (select the appropriate parts in the menu below).

    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 bundled package includes the following:
  • OEM Behr radiator (select for manual or automatic transmission)
  • OEM water pump (choose either the metal or composite impeller)
  • OE BMW coolant temp sensor (located in the water pump housing)
  • OEM Behr thermostat with housing and sensor
  • OEM Behr expansion tank with cap
  • OE BMW upper and lower radiator hoses with expansion tank hose

  • Optional items (which can be added below):
    - OE BMW antifreeze
    - Add a new coolant level sensor (known for failing / throwing "check coolant" messages)
    - Replace the heat exchanger coolant lines for the automatic transmission
    - Add a new fan clutch

    This radiator expansion tank (coolant reservoir) is used on E39 540i from 1997-2003 and E38 740i 740il 750il from 1995-2001. It is a common failure item. 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.

    Part of any cooling system overhaul on the 540i or 740i/iL should include a service for the automatic transmission heat exchanger (cooler). This block takes coolant from the radiator and uses it to cool the oil for the transmission. A blocked or faulty transmission cooler can lead to major transmission faults, harder or hesitating shifts, or even complete transmission failure. As part of every cooling system service we recommend cleaning or replacing the heat exchanger itself and the replacement of the hoses leading to it (see separate product).

    This item fits the following BMWs:
    1999-2003 E39 BMW 540i
