Another excellent video. Thank you. I drive BMW cars more than 10 years. Always fill distilled water %50-50 and blue BMW recommend antifreeze . Also I clean radiators with soapy water every 2000-3000 km. Vaseline all hoses and check them every 6 months. I have never have problem about overheating. Also I have spare parts at the garage ready to change :)

Hi Tim, great info as always. I am using the furlough leave to kickstart my 840 restoration project which completely stalled exactly a year ago when I became ill. Fortunately, I am more or less out the other side so am trying to get on with it. Point being, I am so grateful to you because I can refer to a lot of your images on Meeknet as I cannot remember where some of the bits go! Keep well mate.

Great advice Timm.....I had to have the valley pan gasket on my 840ci replaced as it was leaking coolant. After BMW did that, it blew the radiator apart on the drive home! The dealership also wanted me to replace the magnesium valve covers because they warp and can't be machined as magnesium is flammable. I was told it is an "unacknowledged defect". At $2000 for the pair, I declined and they've been fine with new gaskets.

Good day mate. I had the issue of overheating warning message on idrive. (Bmw e60 2006 n52 525i). I check it out the coolant level.. was good. Then I check the water pump without starting the car (just on ignition), I see the flow was good and water pump is working.. I didn’t drive for couple of days.. feel curious.. then I check under the hood for a leak from thermostat.. no leak.. then I start the car with coolant cap open to check if the coolant (actually I’m using mineral water as coolant) flowing through engine and back to coolant tank ( through small hole in coolant tank).. it’s flowing.. I let the engine run almost an hour and check the temp (on dash) show around 90~94c without running ac and with ac on, temp around 88~93c. And the radiator fan works on/off when ac is off and consistently running with various speed when ac is on.. then later on, I did drive about 1/2 hour in town.. no warning msg and the temp was good.. what could the problem on the day that it shows the overheating warning.. your opinion/comment please. And by the way, on that day, the weather was too hot (36~37c) and i was driving around the city with short distance trip and also the ac was medium level..

Hey Timm, USA here was wondering if you have had this happen on your journey through BMW land? I am losing coolant. My 94 -525 came with a rebuilt transmission $2000, new radiator $900 and new shocks which can be very expensive on that car. I did the rest of this work myself. New brakes and rotors, tune up, lower control arms, fan clutch, water pump, thermostat with new metal housing tightened down the head, battery. It runs smooth as silk and handles like nothing else but it uses coolant???????????? No visible leaks or steam out the exhaust pipe. I ordered a new radiator cap just for the fun of it. I have tried to look under the air intake manifold but no visible leaks but hard to see under there. Might have to take that off next spring because it's getting cold up here in Vermont. I'm thinking head gasket but my compression test seemed good. Problem is I spend more time under the hood than driving this........ I'm actually starting to look a Lexus'. Help.

Someone in the UK had the same problem - the solution follows: Just to wind up the post with the solution to the issue. It was indeed the coolant hose running along the length of the front of engine directly under the manifold. As per the video shown earlier in the post. Most awkward part to get to, and was way beyond my level of DIY. The garage had to remove the manifold the leak was directly at the connection to the engine weak O ring and brittle connection on the plastic hose. There was also an attached hose which showed sign of wear and was also replaced. Along with that I asked the mechanic to check to see if anything else looked a bit dodgy and to replace where he saw fit. Crack case breather hose was replaced, along with 4 or 5 additional connected pipes and hoses. All parts came from BMW directly were approx. £100 The rest was labour.

My 2006 650i auxiliary fan not switching on as required so overheating on idle or dense traffic ! I ordered new switch but noticed after arriving home from 10 mile trip I got out of car but decided to move it about a foot and when I started the car the fan came on and then went off again after a minute maybe reached lower tempature. Or should I be looking at relay switch 🤔 Which is somewhere under a wheel arch I believe.? Do you have a video? I love your e64 you are one of the reasons I have 0ne !!!

Hello Arthur, what makes you think the car is overheating? There is no temperature gauge - are you getting steam or something else?

My 2013 BMW 740Li lately has been having a "Engine Overheated" on the dashboard but my mechanic could not find the cause of the issue after manually checking the Coolant, radiator, thermostat, water pump and the radiator fan. the computer diagnostic also did not show any codes or warning. Prior to the engine overheated popping up, I can hear the fan starting to over work, if that's any indication. Once I pull over and let the car cool for 10-15 minutes, it will drive for a couple of days without any issue but eventually it happens. Any ideas?

Tim, you are a life saver. I have a 1991 850i where the auxiliary fan is cutting on and off. I live in Atlanta, GA, a hot place so I need my AC to work properly. So, via input from my BMW mechanic and various forums, I have decided to replace the auxiliary fan. I used your step-by-step instructions on meeknet to remove my old fan. Thanks so much. The one thing that was really a pain was getting to the bottom bolt that was holding the fan. I could barely get a wrench on it. It probably took me 1/2 hour to get it off. Just curious, any advice on how to access this bolt to make that a little easier? Use a longer wrench, take off the bottom trim on the car, or ? My new fan arrives today so I'll be doing this project the next several days. Thanks so much for your help!!!

I stopped to try to close it and could not open it. It was completely jammed. I figured out he had slammed the hood down before releasing those catches. I went back the next day and showed it to the owner. They had a hard time prying it open and somewhat straightening it but it was just never right after that. Poor old Volvo had a hard life.
