N52 / radiator

mweisdorfer · 07-26-2014, 02:04 PM

Just giving an FYI to anyone who has to put in a new radiator in their E70 with a 3.0 or an e90 with an N52. You will need to purchase an additional coolant host that runs from the electric water pump directly to the oil cooler. Of course you have to take the old one out. The old one branches off and used to feed the lower radiator. The new radiator does not have a lower port. It also does not have any drain plugs what so ever.

So, if you were to do a radiator flush, you'll probably need a brake vacuum, and the from there one would have to disconnect a few hoses and then vac out the coolant from specific vantage points.
