when can coolant and water pump lubricant be installed after using bar's head gasket product?

Doesn't really matter. Bar's head gasket repair liquid mixes with coolant anyway so you don't really care if you do it before or after. The point is you must have enough space for the Bar's stuff to get in the system. You have to remove a quart of coolant from the radiator so it can accommodate the Bar's liquid when added. If you are adding pump lubricant then you have to remove more coolant. Hope this answers your concern.

Can I add this to a clean cooling system that already has the Subaru coolant additive in it?

If it is a Subaru stop leak product we would not, if just the Subaru coolant is in the system and no additive for stopping leaks than that is perfectly fine to add. Please follow all instructions and dosage recommendation on the product. If you have any other technical questions, feel free to contact our Technical Service Professionals at 800-345-6572 or if you would prefer you can use the contact us page on our website.

Safe for a 2011 bmw 760li?

Yes, your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Use on ALL water cooled gasoline and diesel engines. Heavy duty formula works on aluminum and cast iron heads & blocks, along with sealing all other engine cooling system leaks better than a traditional stop leak. This includes repairing head gaskets, cylinder heads, intake gaskets, cracked blocks and freeze plugs. Use with ALL types of traditional or extended life coolant including yellow, orange, pink, red, blue, purple and green silicate based & non-silicate based (OAT/HOAT) 50-50 mix antifreeze, and/or water.
