[@SteveWeltman]

Hey Jake! Great video, very applicable! I had the same problem with the wife's F30/N55 motor. I had little time to get her car fixed so I needed to go to the BMW dealership for another part and got this too ($54!) at the same time. Because the wife's expansion tube cracked at the connector right at the radiator upper hose connector, I couldn't have used a copper tubing replacement. I agree, a piece of copper tubing would have been better than this. What was their engine cost-engineer thinking? Add a few thousand heat cycles and instant coolant gusher. I was just thinking I can replace the upper radiator to upper hose connector with a proper aluminum 3 way fitting, but there aren''t any options that I have seen aftermarket (I in theory could build one with straight aluminum gauge tubing to the ID of the upper tube, drill a port for the return hose, but that's a lot of work for a $20 part replacement!). Project #WeltSpeed

[@amateurvegan2636]

You reckon this could be done with plumbing copper pipe ?

[@Troy9x]

I did the metal piping with some clamps, worked great! 👌🏾

[@nicholashernandezbuzz]

Where did u get the metal line

[@Troy9x]

Nicholas Hernandez advanced auto. Just bring your old coolant hose to get the right size. ( idk if you’ll get the same one I got but if u do you’ll have to measure and cut the ends off the new metal line or it won’t fit inside the original hoses)

[@Troy9x]

Nicholas Hernandez you should get a couple small screw clamps too, maybe at Home Depot . The old ones might not work good enough to hold the metal line in place.

I would spend the extra $30 and change the connecting hose also because that nipple will break soon. When I changed the hose I can see the nipple was already weak so rather just change it out and keep the car running longer.

Seems to happen to almost everyone. Might just be the “mod #0” when getting the car in your possession

[@ijdad99]

My girlfriend's car had the same problem. She was stuck in a gas station. I took out the plastic tube and brought it to Napa and asked if they had something to fit. The guy found a perfect match... tubing for an air line. I bought 2 feet of it for $1.24 and she was back running in a few minutes. That got her home but I bought the actual part and installed it a week later because that tubing may not be able to handle hot coolant if it's only spec'd to handle air. But it worked perfectly and I was able to brag that I did a $1.24 BMW repair. And really, that's what it's all about.

[@Fix_It_Again_Tony]

This didn't happen to me in quite the same way, but I was moving that coolant tube to take the fan out for some reason and the tube broke in about three places. I bet that plastic gets brittle over time due to heat cycling. I've also needed to replace that upper rad hose because the nipple broke off. I noticed there was some blue crystallized coolant around it so it was probably already cracked slightly before it broke off completely. Last time I tried to do the coolant bleed, I couldn't get the pump to come on. I had to do it through INPA. I probably just didn't hold the gas down long enough.

[@jake_spence]

Yup, that plastic line and the nipple are both brittle. Not sure what BMW was thinking... but as far as the coolant bleeding procedure, I've done it a bunch of times on different E9X and E8X BMWs, works every time but you definitely need to hold the pedal down and do the HVAC settings properly. Give it a few minutes and it'll start going.

[@DigitalDissident]

If you unplug the radiator fan the water pump runs automatically because it assumes u need additional cooling. Unplug fan connector, put ignition on, pump will run...

[@SuperHbkforever]

Hey Jake! I have a completely unrelated question to your video, but I have a 2008 335xi and I'm running FBO with upgraded fuel pump and e50. When I run the ethanol tunes, my car tends to ubderboost. It the lower gears it can be about 4psi under target. I noticed in some of my logs that my DME sometimes tries to compensate by raising load target but the boost stays put. Yesterday I got into a race and made it to the top of 5th gear. In that log I finally got close to target boost at 18psi as target was 18.5. I recently replaced some brittle vacuum lines in hopes to fix it but it didn't fix the problem. I'm at the point where I can't seem to find the cause of my issue other than the FA t that I'm on the original turbos at 178000kms or About 115000 miles. Do you have any ideas?

[@joeotto775]

Check over all your vacuum lines again. Especially the two directly behind the oil filter housing. They crack all the time on the bottom where they're pushed over the nipple. Be sure to remove the lines when inspecting so you can check the bottoms of the lines. Have a spool of new vacuum line ready. After checking vacuum lines, I'd recommend going over all your boost piping. You said you're fbo so double check those intercooler connections and up pipe connection. Check charge pipe to throttle body connection. Remember, in your case if you are making lots of boost but you're 4psi or so short then you likely won't be able to see the crack or leak. You'll need to go over all clamps again and vacuum lines. After that, how old are your turbos? Lol Hope this helps. - Joe

[@jake_spence]

Hey man, thanks for watching! I think Joe is covering the first bases pretty well. There is no reason the fuel will affect your boost levels. So check the simple stuff first. What tune are you using?

I have a 2008 E90 (335XI) which is leaking coolant somewhere on the passenger side of the engine and it is causing a lot of smoke as apparently the coolant is touching something hot.

If you have any ideas I'd appreciate it as it is causing a lot of smoke. Thanks and nice info in your video. Phil

[@ijdad99]

I could be wrong, but that sounds more like a valve cover gasket that's leaking. It's the typical location for smoke as it drips on the exhaust. It's not a bad DIY job but you need the special ultra long 10mm. I ended up using a 6 pt 10mm wrench that I bent in a vise and a grinder to thin out enough to rotate to engage the wrench again... a 12 pt works have been better. Or buy the part from Amazon. But I realized this hours into the job with my girlfriend (her car) standing there, so I had to go into HERO MODE.

@@uptownphotography -. Google the following... CTA Tools 1710 Deep Socket-10mm It's available on Amazon for just under $13. In the reviews, it mentions being used for the valve cover gasket. It's for the 3 ground pins. Also, if doing the repair following the video on KZbin, definitely take the time to move all the wires out of the way where the engine computer is. It makes getting the valve cover back on much easier. BMW suggests replacing the valve cover at the same time. I did this for my girlfriend and suggested we just do the gasket for $20 instead of the cover for over $500. That worked for 3 years, and then the cover failed, which caused the car to lurch when the gas pedal was pressed down for fast acceleration. So she had to have me do that in the end. Second time is a breeze... which is how I know to move the wires. That 5 extra minutes saved 20 minutes with wireless knocking the gasket off. Live and learn.

Long story short, towed it to the shop to protect the engine from overheating, and the quote to fix this came out to $10,450. I’m so devastated.

[@WayneBanga]

10K for a coolant leak fix? Something is wrong about that quote

[@fana406]

I got a 2nd quote and it was way cheaper to fix. About $3K

[@lucas_theofficial5230]

Well thats not my problem and i dont know what else to do, I replaced the coolant block thing that you pour the coolant into and replaced all the hosing, i cant find any leaks, but my coolant is always low with in like a day or two after filling it up

[@alexshotU1]

I had a coolant leak on this exact car and it was not too bad but today i went to drive it feels shakey and sounds like its gushing out kind of. Car seems to get really hot does not tell me its overheating but i see a puddle of coolant and also a drip that is located right next to the tire i assumed it was a water pump before i saw coolant on this side of the car oposite of the water pump although there is also a leak near the water pump im wondering if this is a new leak to maybe a hose? As well as the pump. Would anyone by chance know what is by the driver side on this car other than water pump nothing in the very front its dry but when it comes to about the tire its leaking.

[@in54ne82]

Best thing to do is replace the complete cooling system including water pump and thermostat and be done with it.

n54 power if u can afford yeah

[@jake_spence]

That's true! I've had two plastic water pump housing crack and leak as well.

[@starwarsguy123ful]

Any idea how much this would cost?

[@in54ne82]

Go on rock auto and buy everything. Its should be around 600 bucks. Water pump thermostat, radiator, all hoses, reservoir. Around 1000 if you get a 2 row car radiator.

[@starwarsguy123ful]

@@in54ne82 alright thanks man I’ll have a look 👍🏻

[@salviog_]

This shit happened to me 😂😂 I was sad af until my homie showed me this and then I went to auzo zone and put a fuel hose there and it’s better than the stock one tbh

[@lys4636]

Sameee

[@ssplurged735]

How hard is installation? In the same position and not sure how to access the fuel hose

[@orion1two]

About to do this. My top radiator hose is leaking... the one that goes into oil filter housing. Not terrible but leaking on belt. smh

[@jake_spence]

Better take care of that before it gets worse or leaves you stranded, take it from me! Lol.

[@heeltoe6845]

Definitely get an aluminum hose outlet. The plastic ones disintegrate going in the filter housing. In fact, you may just be able to replace the plastic piece.

[@orion1two]

@@heeltoe6845 Thanks man, I've found aftermarket tubing for all the other pipes except this one. That's exactly what's happening it's leaking at the plastic fitting.

[@GeneG-wk2mz]

Yes I had to replace mines on my 550i that dam little pipe and hoses all together was 70 dollars

[@jake_spence]

Yeah, the little stuff adds up for sure, especially if you get OEM parts.

[@mohammedashfaq3892]

[@GeneG-wk2mz]

Mohammed Ashfaq it’s the hose running to the reservoir trace it it has a pipe underneath wear the hood latch you how to take that hold assembly off it’s under there

[@GeneG-wk2mz]
