R60 cooling system drain procedure
#4
Recently performed a drain and fill on my R60:
Since I didn't have a vacuum system to pull the coolant out of the block and pump, I repeated the process a week later after the new and old had plenty of time to mix.
- With engine and coolant cold, unhook the hose on the bottom of the radiator, open overflow tank to allow coolant to drain out
- There will still be coolant in the block and water pump, so reattach the hose and fill the coolant tank to the line
- Turn heat and fan on maximum, leave the overflow cap off, start the engine
- Watch the coolant level in the overflow and continuously top off to the line, this can take 10-15 minutes
- After level is stabilized, allow system to cool, then re-fill to line
- Drive car for 5-10 miles, then let cool and check level again

Happy to help! I used Zerex G48 coolant. Took about a jug and a half to perform 2 drain and fills.
The hose is very accessible an visible when you jack up the front end. The fitting is held together with a clamp that is easy to remove. You can see it here:
