Which coolant the 1998 BMW 5 Series takes
The factory coolant is BMW Genuine Blue Coolant. Mixing coolant types can cause sludge and corrosion, so top up with the same product, or drain and refill completely when you switch. Other brands are fine if the jug says they meet BMW N 600 69.0.

What a coolant change costs
At roughly 2.8 to 3.2 gallons of capacity, the coolant itself is about $42 to $96. A shop charges $70 to $120 for a drain and fill, or $100 to $250 for a full flush. Use the specification the manufacturer lists - mixing coolant chemistries is what turns a cheap service into a water-pump job.
