Just redid the entire Coolant system on my 2003 330i Manual. Couldn't have done it without you, Jason! Thanks!! Not sure if your E46 has more stuff in the way of the block drain, but undoing one 10 mm bolt freed up a flex hose attached to the power steering and that allowed me to go almost straight in with a socket wrench. Slight pivot. Found the bolt disconcertingly easy to loosen, and no crush washer. All good now thought. Thanks again!
If you are not going to replace the water pump, I _would_ advise opening the plug on the block - it is at the same level as the water pump, so there is no need to do it if you _are_ removing the pump.
looks easier than what I went thru today. I decided to take off and clean my fuel injectors because I am getting a stall but no codes so i fgure its a fuel issue. New fuel pump, new fuel filter already..... SO, I take off fuel rail, one of the position clips that holds the injector to the rail flew off, and I lost it for 4 hrs in the engine. Wish they would paint them things like bright yellow or something (STUPID CLIP). Then I get it all back together, FORGOT to tighten the 10mm bolts down that holds the fuel rail in, started car.... gas EVERWHERE.... lol... just used some carb cleaner, degreaser and a hose to clean that mess up..... so i take it all back apart... tighten the damn 10mm bolts down... and the 1st one, the head BROKE CLEAN OFF, leaving the threaded part in the hole... had to get my "Speed Out" take the bolt out... now that I dont have one, I took one off the 2ndary air intake housing for now... but that bolt hole now seems to be a little stripped out, bolt wont get tight but does screw down just fine.... LOL... What a damn day... turned a 2 hr thing into a 8 hr job.... LOL.....
hey 50skid… i see that you kept having trouble with finding a cleaner way to drain that bottom block plug. i saw an answer on another video which says to keep the coolant cap and bleed screw closed when opening that, this will prevent it from gushing out… i’ll try it out soon too because i have to and let you know if it works..!
I am currently doing this and the drain plug on the bolt is very tight I got it to turn but I feel like it's going to shear off, if I remove the water pump will it drain all the coolant from the block as the drain bolt will?
I was actually looking for the heater outlet hose but you didn't identify them. I'm needing to hook up a Flush 'n Fill 'T' and I can't pinpoint the correct hose to flush through.
Can you still flush it this way if you're replacing the coolant with different coolant? Someone used the wrong coolant (green) in the car I have, and I want to completely get the green stuff out of the system before adding in blue coolant.
I noticed you have permatex in your thermostat housing... why? I am about to do the cooling system in my e36 and I wonder if I should use permatex or not?
You might have a blown head gasket. Watch my leakdown test video to see how to introduce air to the cylinders and see if it's coming out through the cooling system. You can also buy a chemical test to check for a blown head gasket.
Basically the intake manifold removal/install videos are what you need to follow to replace those pipes. Once you have the manifolds off you will see clearly how to unbolt them and get them out. Be aware the part that is stuck into the head and block may break off because it's deteriorated and you'll need to dig it out with a screw driver.
@@joelgarcia6307 dont. bmw is phospate and nitrite free its rare you find coolant brands that meet the spec. you literally save 8$ and risk eating alll your hoses out. have fun spending 300$ to refresh that in 40k miles or less
i would rather make a mess and get that powerful stream of coolant from the engine drain plug and with that flush out more of the dirt that may have collected.
hi 50kids. I don't have to remove any of those parts but I just want to drain coolant from block of e46(m54). where is exact location of drain bolt? Do I have to remove any parts to get reach there or is it easy to remove? thanks
Hi jayson im doing a expansion tank replacement but those upper hose connected to radiator tab is very tight what would you suggest to loosen it out? Ive tried silicone spray still tight.thank you.
You just slowly twist it back and forth and while pushing out with a flathead. Make sure you’re on the right layer with the flathead where hose is attached.
Doing it this way will leave a lot of old coolant in the system. I came up with a much better way and that is to additionally remove the heater control valve and also to disconnect the return hoses from the expansion tank and then pipe some compressed air into the heater valve hoses and this will remove a lot more coolant. I use a big tray (2ftx3ft) from a dog kennel to catch the liquid as it comes out from everywhere and then a fluid transfer pump to put it into gallon jugs. Little mess.
Good tip What's also possible and might be abit easier. If u pull the 2 heater hoses that are on the expansion tank.. Remove waterpump and then fill some coolant or water into the upper heater hose... Then take a compressor.. Put the the air pistol in the upper Heater hose..make sure u got some rag around it to close it all up.. Then just blast air into the system and ull see all the coolant coming out of the waterpump..proceed these steps until u either got fresh water out of the waterpump hole or fresh coolant. In my case I had pink coolant in my system and I changed it for blue . So was easy to spot when it was all blue I also put the heater on hot This way u don't have to remove the engine drain plug Hope this helps for some of u.. Either is a good one

Where is the plug ?
I have a 2004 bmw and mines doesn’t have a blue drain plug ??

Thank you so much! I've been dreading doing that plug so that I can do a cooling system overhaul. I just do not trust my jacking surface.
Screw that plug! I agree

It’s 3 years later.
Did it work bro?

Check this video out for the explanation of why: ruclips.net/video/dmzkwYv88A8/видео.htmlm56s
It was very nice if you let see the radiator drain plug
It's blue. You cannot miss it
Where you find this perfect draining bucket?
Thank you!
What is the proper name of the lower hose that connects to the block called?
Still didn't demonstrate it though, smh.
Mate pay for coolant twice rather than paying for that new automatic trans cooler as they usually breaks
True ??
Awesome, thanks
I've done everything but can't get my sons 325 I 2004 to stop running hot. Can anyone help
You might have a blown head gasket. Watch my leakdown test video to see how to introduce air to the cylinders and see if it's coming out through the cooling system. You can also buy a chemical test to check for a blown head gasket.
50sKid thanks I'll check. Found out yesterday the car will no longer start
Stephen Herron last time my car overheated and it wouldn't start , I had snapped some belts and some hoses because of the overheating
50skid do you have a video on how you replace the water pipe on the e46?
Basically the intake manifold removal/install videos are what you need to follow to replace those pipes. Once you have the manifolds off you will see clearly how to unbolt them and get them out. Be aware the part that is stuck into the head and block may break off because it's deteriorated and you'll need to dig it out with a screw driver.
Why didn't you just use the drain plug on the side of the block?
Are you using regular green coolant? I was lead to believe that we must use only bmw blue.
Shawn P I'll have to give it a try cause that blue stuff is expensive

It's underneath the exhaust manifolds on the #2 cylinder.

what about draining coolant from engine block from under engine?
Doing it this way will leave a lot of old coolant in the system.

In my case I had pink coolant in my system and I changed it for blue
. So was easy to spot when it was all blue
I also put the heater on hot
This way u don't have to remove the engine drain plug
Hope this helps for some of u.. Either is a good one
removing water pump... how is this easier just curious. id rather not
@@ikeepgettinbanned5525 haha Okey ur right.
I only made this remark cause i was thinking he drained his coolant in order to replace waterpump
My bad
Does your 13 mm M8 bolt on the side of the block also have a U stamped on the head?
Yep, why?
That is the wrong way to fully drain
