Video tutorial on how to bleed the coolant system on a BMW equipped with an M62 (4.4L V8) engine. This procedure applies to a BMW 540i, 740i, 740il, 840i, 840ci, and 840csi. Possibly other BMW models may have a similar procedure as well with other style engines. Distilled water is recommended when mixing coolant for your vehicle as it does not contain any additives which can cause the system to plug up unlike water from the tap. This particular tutorial was done on a 1997 BMW 540i.
