Help my Coolant Leak..

[pike_account]

Hi, please help me.. give me some advise!!

my E90 320 is giving me problem.
i dont know BMW cars are so problematic till i own 1st time.

FYI:
i had already change 6 new original coolant hose & a new radiator.

I send my car to workshop many times and even changed these parts, i still cant find where's the REAL problem is. after i parked few hours i check and i still cant see any leakage on which hose's, on car parking lot and even i can see bottom there is some green coolant water internal.

even after change i still discover my coolant tank water running low after another day. And i need to top up 1litre of coolant/water every 3-4 days.

can someone please kind enough recomend me a expert good workshop with reasonable charges to resolve my problem ASAP... provide me workshop telephone and address thank you!!

hi pike, the coolant u used might be rather corrosive....why don't u try just water only for the next couple of days and monitor.
it would help if u can try checking there's any wet spots within the engine bay or below the car.
u can also check the reservoir portion of your radiator and see if there's any leaks there
sometimes leaks are not just due to the hoses, especially since u have changed it

radiator cap must be of the right pressure type. if not it will prematurely overflow. also, make sure overflow tank is not filled above the mx line or it will also cause issue.

other than that i guess it could be minor leaks at joints. that would need some radiator presssure leak test.

hope you get to solve it soon.
