Just draining the radiator will actually drain a pretty small amount of the total coolant in the system….the radiator doesn’t hold that much in comparison. You need to do both the radiator and main coolant hoses to water pump to meaningfully do a ‘coolant swap’.
I use the 50/50 euro premix from the auto store and my car has been fine . It’s not even blue, but green lol. Just make sure it’s the correct mixture the color doesn’t matter
You sure? I thought the chemical components of the coolant was special because of the reaction with the magnesium alloy of the block of the green coolant was bad for the block.
i did it the wrong way. run the venting process with the screw CLOSED and the cap open until you dont see anymore air coming through, then try to get the right amount of coolant in the expansion tank and close it so it can pressurize and run throughout the rest of the engine.
It looks like you added too much coolant. If you add too much, the pressure will increase and leaks or cracks may occur due to pressure in the circulation passage or radiator.
@@buildanddrive my mechanic told me the code for it came up. my heat also blows cool air then i get the overheating warning n my car stops accelerating
@@aliasSix In europe, I've only found 2 brands of BMW coolant that say they support the N52 engine (magnesium alloy block) so you cant just use any coolant because it can have a chemical reaction of its not compatible. For other engines, very possible you can just put any coolant into it.
Thank you I just bought my first bmw 328i e92 I'm having a blast and I've had to rewvent my mechanic skills for this European way of life which I might say it's Theeeee best if you want particle buy a Kia 😂
Wow this couldnt have come at a better time dude. Thanks! 🙏
Summer time bro. Get that cooling system running good!
@@buildanddrivemine leaks from the lower hose is it worth getting the tank or replacing the hose
Same procedures for e90 320d lci(i think mine was hydraulic system)
Yes, just look for the metal lines coming out of the rack.
Hello Mark, Can i perform same process on e92 2011 n52k engine ?!
Yes, should be fine.
Overfilled my coolant like you and already had the bottom stuff back on the car so i used a hose and siphoned the extra out
Smart 🤓

Yes, if you tilt the car forward a bit, it should drain a lot of the coolant out.
Excellent video. Just one thing, at 2:32 mark, did you say that we CAN use any coolant or CAN'T use any coolant ?
Thanks
Technically you CAN use any coolant but I just stick to the BMW stuff. It's not that expensive. I have 80,000kms on it and it still looks fine.

Always use blue for bmw
@@buildanddriveHe’s right it just has to be a specific type: Silicate Enhanced Hybrid Organic Acid Technology or Si-HOAT.
Can you do this same technique on an X3?
Yes, I assume so
While draining the coolant can I pour water in the expansion tank for a better flush
Yes
What tool did you use on the drain plug?
He used a butter knife 😂
can i get all out with that one screw? no need to get the car warm so it opens up the whole cooling curcuit like it used to be on older cars?
You can almost get all of it out with that one screw. No need to get the car warm.
@@buildanddrivethank you! 🙏
are you sure you run the venting process with the bleed screrw and cap tight?
i did it the wrong way. run the venting process with the screw CLOSED and the cap open until you dont see anymore air coming through, then try to get the right amount of coolant in the expansion tank and close it so it can pressurize and run throughout the rest of the engine.
Can i just refill the coolant without having to go all down that process?
You can try. It will cause a lot of air pockets though.
I’m interested in learning how to change my thermostat???? On a 5 series?
Watch this video, I reassemble the water pump and thermostat. Just reverse the order : th-cam.com/video/6OnnfZxV5lE/w-d-xo.htmlfeature=shared
It looks like you added too much coolant. If you add too much, the pressure will increase and leaks or cracks may occur due to pressure in the circulation passage or radiator.
Yes, at first I thought there wasn't enough, then I added too much
Can I just fill the coolant without water
No, the coolant is an anti corrosion liquid, the water helps with the cooling. You need water.
My e90 has an intercooler, so there is no drain plug!!! I wanna cry. do I have to unplug the lower hoses? I can't believe it's that complicated!!!
Is yours a 335i?
@@buildanddrive No, 320D (I think it's an European version that doesn't exist in the US)
Nice 👍
Thanks Sally!
i realized my coolant has been EMPTY since 2020 and i’ve had no problems😭 now once i add coolant, my water pump fails 🙄
LOL. How do you know your water pump fails?
@@buildanddrive my mechanic told me the code for it came up. my heat also blows cool air then i get the overheating warning n my car stops accelerating
Did you ever get it sorted out? I just paid 1500 for the same thing @@dolo_kaayy
Thats crazy
You can use any coolant
Really?
@@buildanddrive every bmw I’ve bought has had different color coolants they all run perfectly fine .

Bad ass
Well
I messed up
I used water 🙃
Only water? Are you living in a cold climate or only hot?
60 to 63 range - somewhat hot
The engine and radiator corrodes without coolant. May lead to head gasget leak among other problems.

The 328i is a fun car. Hope you get the basics sorted then you'll have a reliable BMW... Which you don't hear so often 😂
Practical lol
guy with a mask lol
Yep. Like chrisfix
What tool did you use on the drain plug?
A screwdriver
@@buildanddrive this plug is one time use im hearing. And has clips?
