I've got a very small coolant leak somewhere bu I can't find where.
I need to fill around 1/10 of liter every 100 km or so
- All hoses are new, all new clamps.
- All small tubes thoroughly cleaned.
- New waterpump
- Coolant: deminiralised water with anti freeze
- Coolant color: clear
- No bubbles with open expansion tank when engine is running and hot
- No smell in the interior
Any ideas? Pressurizing the system somewhere to see where it pops out?
BMW was kind enough to give you a schrader valve onm your expansion tank - don't take it for granted, its a luxury.
Turn your compressor down to 1 bar.
Remove the oil fill cap.
Put the tire filler on.
Put your ear close to the cam cover.
Pray to your higher power that you don't hear anything there.
Finally - look for leaks that DON"T make you want to commit suicide.:haha:
