Complete Cooling System Overhaul Package - 1997-1998 E39 528i
This is a compete cooling system overhaul kit, which includes all the common M52 cooling system failure parts bundled into a complete package. This cooling system package is for the 1997-1998 528i with the M52 engine with either the manual or automatic transmission.
Much of the E39 cooling system is shared with the 3-series cars of the same era. Which means the potential for serious cooling system and engine-related failures. Several of the primary cooling components are prone to failure within 60k 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 radiator & 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 cooling system. Our kit includes one OEM Behr radiator, an Original BMW water pump (with updated composite impeller), thermostat, radiator cap, and new radiator hoses.
Basic Kit Contents:
17111702969, radiator (OEM Behr)
11517527799, water pump (OE BMW)
11537511580, 88�C thermostat (OEM Behr/Hella)
11531740832, upper radiator hose (OEM Rein/CRP)
11531740481, lower radiator hose (OEM Rein/CRP)
17111427156, expansion tank hose (OEM Rein/CRP)
17111742231, expansion tank cap (OEM Behr/Hella)
Cooling Kit Options:
E39 Water Pump Options (click to expand) OE BMW with composite impeller. The original BMW water pumps had plastic impellers which degraded and failed. The latest design uses composites that are much better and will not corrode. Compared to a metal impeller, the composite is lighter so it's more efficient and it will not wear out the bearings. We don't even offer the metal impeller pumps with this kit because the BMW composite one is so much better.
Stewart high performance. The ultimate in M50 water pumps! It features a stainless steel impeller, heavy-duty bearings, a better o-ring seal, and flows 20% more than the stock pump. If indestructible is what you're looking for, this is the pump to go with. It also comes with a lifetime warranty for piece of mind. E39 Expansion Tank (click to expand) The original expansion tank is prone to cracks and leakage. Again - it's made from a weak plastic. The material has improved over the years but the only option remains an OEM plastic tank. It's a good idea to replace it if you're doing a whole overhaul. Don't re-use the original tank if you're going to the trouble of replacing everything else! E39 Thermostat Housing (click to expand) The original BMW plastic thermostat housing is brittle and does not seal well. We only sell it under protest. Instead we've been selling this aluminum housing for the last 20+ years. The aluminum does not have the same shortcomings as the plastic one. We made this item an option in case you already have the aluminum housing.
