Bmw E60 Thermostat Problems

The most common problem with the electric coolant pumps is a fault code for coolant pump volume.

Bmw e60 thermostat problems.

2007 bmw e60 525i 528 530 overheating warning diagnosed and repaired. But now i bought a gallon of bmw coolant and 4 gallon of sterile water because i want to remove all the old coolant and what i added. Common problems on the e60 m5 and its s85 v10 engine. It s also a frequent problem on the n54 i blew mine at 42k miles our e60 blew one at 60k miles and our e90 had a failed one at some point as well.

Any recommendation on how to remove all of it out. Throttle actuators the s85 v10 has 10 individual throttle bodies which are controlled on two banks by two throttle actuators. If you remove the water pump from your e60 and plan on reinstalling it store it with coolant inside it. Otherwise it will corrode and fail shortly after reinstalling it.

The actuators are known to go bad and when they do you re looking at about 1000 a piece in oem part cost alone plus labor to fix it. Bmw s use a electric water pump rather than a traditional water pump. I am not a mechanic and take no responsibility for any damage or injury caused by anyone attempt. This is how i changed the egr thermostat on my bmw 530d e60.

Most modern electronic thermostats such as the ones found on late model bmw s are designed to fail in the stuck open position these days to avoid ruining the engine by overheating. The car is a 2004 bmw 525i e60 m54 thanks nick september 23 2014.
