My radiator light inidicates my coolant is low and I check and refill it with antifreeze. Within a 2 or 3 weeks the coolant needs to be refilled again. The car does not leak anything while parked. Could this be leaking while I am driving? Thanks
Coolant leaking on 2005 BMW 325i
It is very possible to have a coolant leak such that no coolant leaks onto the ground when the vehicle is parked. The cooling system of your 2005 BMW 325i should be pressure tested using the proper equipment in order to find the cause of your coolant loss.
If you don't get it professionally checked out you won't have to worry about adding coolant. YOU WILL NEED TO REPLACE THE ENGINE!!!!
