great video! appreciate you posting that, I had a blown hose in a parking lot today and couldn't get the radiator to accept coolant, had air in the system, this helped me get it out. Thanks!

Thanks alot for your videos, you are helping alot! And I love that you have a sense of details when explaining, that is crucial and unfortunaly something many jumps over. Quality conent, thanks again! 👍❤️

Bleeder screw off Heat max lowest level Fill coolant expansion tank to the brim Keep adding little bits of coolant until no bubbles exit from the bleed screw Close everything up. Go drive.

Great Video! Thanks for your Time and kindness!!!

Thanks for the video, I'm currently getting stressed out trying to bleed my 540i... I will be trying your method tomorrow morning.

Does it work with 535i ,i have this problem, when driving i get heat but when idling standing still ,no heat.

I have this same car. My problem is when the car is cold and have been sitting for a day or two when I go to check my coolant the reservoir is full of water and has pressure to the reservoir cap what can cause that and ever other day once the car gets to its normal temperature the check coolant level sensor comes on 🤔

Thanks For all your good videos! I'm curious what is the normal operating coolant temperature on this M52 engines on e39 1998? Today in the UK on highway 95/97C On traffic goes up to 101C is that normal to climb over 100C? And when I squeeze the lower/thermostat hose I feel thumping/pulsation in the hose a feel too much pressure?

best tutorial out there. you sir is a life saver.

Hi If you replace with new all the cooling system components on E39 528i 1998 M52 engine and you don't see coolant mixing with the oil.... And you have rock solid hoses, what's would be your suspect for this. BMW dealer here in UK is telling me this is normal but they are exceptionally hard can't squeeze them? When I drive temperature is solid 94C but idling goes to 102 and looks coolant doesn't circulate proper thru the radiator to activate the viscous clutch /fan.

Great tutorial! I have a project 540i that I bought this spring -- I swapped the oil and the gas, and fired her up. The engine hadn't ran for about 2 years, and I guess I got overly excited. I started revving the engine to flush the hydraulic lifters, and it wasn't until about 60 seconds to 90 seconds later that I realized that I should probably check the coolant. Woops! It was bone dry. Must have had a slow leak somewhere. I know these engines are pretty heat-sensitive, but I've also read that actual head gasket failure is rare. Do you think I did any serious damage in that 90 second window? I was revving at about 3000 rpm, and when I shut the engine off, there was a slight burning smell from the engine bay (again, the car hadn't ran in 2 years, so this smell could be anything.)

Hey great video, I replaced my thermostat and now when I went to turn on my car after adding coolant the tempature niddle went to the hottest point I guess I have air in the system or something please help

MondragonDj Yes you most likely have air in the system still, be sure to bleed the system before it causes any damage.

Will this help with a visible leak? My 540i has been leaking coolant for the past few days.

Big problem. I did as you said. When I went to run the car with the cap off, I left for a couple minutes. When I can back the expansion tank float didn't move (still a few inches above proper level) and when I got in the car the temperature needle was pegged at red. I immediately shut off the car. Am I going to need a new radiator or something?

That is a big problem. You should make a post in www.bimmerfest.com/forums/forumdisplay.php?f=103 There is a chance you came back in time to turn off the car before damage was done, but after the temp had climbed above the range the gauge displayed. Good luck. Never leave your car till your certain it's circulating coolant properly!

Jason Najm You may have been lucky and it didn't do any damage. The engine may have ran hot or it was just air trapped around the sensor giving a false reading. I can't stress enough, ALWAYS keep an eye on the engine and temperature gauge when bleeding the coolant system. Actually that applies to ALL coolant system bleeding procedures. When over heating a car, it can warp the heads and damage the head gasket. Very expensive job to repair.

No, you have the leave the cap off in order for the air to escape until the car is at it's normal operating temperature for about 20min. Once the coolant hasn't gone down, you can turn the engine off and reinstall the cap.

When I take my cap off it bubbles and boils over so bad it's rediculous, I had to leave the cap on and slightly open the bleed screw which allows air/steam to escape. It's been a long process of doing that, letting it cool, adding more coolant, driving it, it overheats and indicates 'low coolant', letting steam out of bleed screw, letting it cool down, adding coolant... I'm making progress and hopefully on the right track.

BMWs tend to hold heat for a long time, just their nature. However make sure you have the cooling system properly bleed. Is the temperature at a normal range or too high?

Are you leaving the cap on? Air could also be trapped which is why the level is kicking up like that. Try squeezing the lower radiator hose with the engine off and cold. Don't overfill the reservoir and elevate the front of the vehicle.

Just tried this method. Did nothing but boil out my coolant. I'm so confused on the different methods of bleeding. Apparently none of them want to work for me

Ryan Choudhry Have you elevated the front of the vehicle??? This takes time and patience. Unfortunately these engines aren't the most user friendly to bleed either compared to other systems, but be sure not to overheat your engine and always keep an eye on the temperature.

@markbhoward

agreed, leaving the cap off isn't working for me. Slightly opening the bleed screw works better. Fully opening makes coolant gush too. I've had to drive, overheat, open bleed screw, cool, fill, repeat. I think I'm slowly making progress. I'm sure the dealership could fix this in an hour and charge me $500.

having the exact same issue, did you fixed it? and how?

I followed your video, I had the cap off. Turned the car on and had the heater at max. First I saw cold coolant coming from the top cold for 15 minutes then hot coolant started coming out like hot lava over the expansion tank on the ground. I waited abut 4 to 5 minutes then I put the cap on while engine was running . I realized the temperature start heating up a little bit toward the right pass the center line. I turned off the engine. The next day I realized that the expansion tank is empty. Then I filled up and repeated the same procedure. Again the temperature started riseing after I saw the hot liquid inside the tank when I put the cap on. Should I repeat the procedure again? The heater was semi warm not at maximum. We just changed thermostat as well. Is it possible that the thermostat is bad? Amir

Yara Elmjouie These systems can be somewhat of a paint to bleed and it takes time and patience. The reason why it overflowed from the tank is most likely there was still air in the system which pushed the fluid up and over the tank. I had to repeat my procedure about 4 times until the system was finally bleed. What work did you do to the car??? An air pocket could be causing the temperature to rise, but still be very careful and don't let it get overheated. The thermostat could be possible stuck closed and that would be causing your car to run hotter as well.
