Customer Question
When I add coolant...

When I add coolant to my BMW 745i 2002 the coolant pours out of two hoses, one on each side back of transmission. Any idea on the problem. Thanks Lorne

Mechanic's Assistant: How many miles on the car? How has your mileage been lately?

I just bought vehicle and have replaced the coolant pipe. 225,000 km.

Mechanic's Assistant: Are you fixing your 745i yourself? What have you tried so far?

I am fixing it my self, I have replaced the radiator and the coolant pipe that runs through top of motor.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I want to know where these two hoses connect and why the coolant is coming straight out.

the coolant only comes out when vehicle is running. Thanks, Lorne

I understand, these are the heater hoses. These hose run to the front and auxiliary heater. Did they burst or are the connections just worn? Can you tell?

Customer reply replied 7 months ago
These hoses hang down on each side of the transmission, there is no evidence that they were connected. But maybe that is a possibility?
BMW Mechanic: Todd M, ASE Certified Technician replied 7 months ago

Was there work done to the vehicle? What were the events that led up to this issue?

If you can, look to see if there are connection/pipes coming out of the firewall(toward the middle or right side) that are bare?

There are three hoses coming out of fire wall and all are connected to hoses (2inch).
