If you are the type of person who, rather than fixing individual components as they break, likes to refresh everything at once to make sure your cooling system is stout, then you're in the right place. Our overhaul kits give you the option to purchase everything you need to get your cooling system back in check at once. Our overhaul kits generally include thermostat, water pump, radiator, hoses, and expansion tanks.

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 E39 M5 with the S62 engine.
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. Keep on top of the cooling needs of your engine for your own piece of mind. Potential buyers also see the upside of a properly maintained car with receipts. Our bundled package includes the following:
OEM Behr radiator
OEM Laso or OE BMW water pump with gasket
OE BMW coolant temp sensor (located in the water pump housing)
OEM Behr thermostat with o-ring
OE BMW o-rings for the inner coolant tubes
OE BMW expansion tank cap
OE BMW upper and lower radiator hoses with OE-style clamps
OE BMW expansion tank hose with OE-style clamps Optional items (which can be added below): - OE BMW antifreeze - Add a new coolant level sensor (known for failing / throwing "check coolant" messages) - Add a new plastic expansion tank (if it's never been changed it's a risk of a crack or leak) - Add a new fan clutch
