I was fudging around trying to install an fmic and after i was done buttoning everything back up, it came time to jack the car back off the jack stands. I was using the front central jack point and either my jack slipped or it broke it seems to have punctured something and a blueish green liquid drained out. Only two possibilities, either washer fluid or coolant. Hoping its not coolant or the actual coolant reservoir I may have just dislodged a line. PLEASE HELP SOMEONE!!!

Update: Here are the pictures

Uhhh....take the covers off and see what broke? I don't know what you're expecting us to tell you over the internet without seeing it.

I was going to edit original post after I realized I didn't put pictures but then it started raining. Will post later today. Was just wondering if anybody knew any nearby lines next to the jack point that it could be

You broke the plastic heater hose that runs from the thermostat across the subframe and over to a secondary hose that then connects to the heater core near the steering column. Car is not drivable until it is repaired. The hose is around $120.

Yeah I looked up the part. About $100. Would you know how difficult it is to replace? Couldn't find a diy in the forums

I posted a DIY for the N52 and show how to replace the hose. The 335i has a different hose but the procedure should almost be the same.

Why would such an important hose:

1. be plastic and crack-able!?

2. be routed at the very bottom of the car where the jack point is!?

That is a helluva design oversight

It is pretty much protected by the subframe first off. Second, not sure why the OP used a jack that "broke". It's possible he was using the jack incorrectly. Third, when lifted by a commercial car lift, the lifting mechanism never comes close to the hose line.

Well, you'll need $100.00 and about $25.00 for a gallon of coolant. You might just buy 2-3 gallons and do a coolant flush while your at it.

the above is the jack post i used. the jack broke under the weight of the car even though it was rated for 2-tons, thats a separate issue. the coolant return line is directly in front of that and protected by nothing. and i do not own a commercial car lift in the sense of raising the entire car.

yep. since it was my daily driver and i was done rummaging around with the car i took it in to a shop to fix the hose. labor was about $500. whole ordeal about $650. i blame the jack. it was a walmart brand floor jack. In hindsight sure I should have a heavy duty one but if something says its rated for 2-tons, you expect it to be

ECS tuning has a sweet Jack and stands . The stands are very pricey though.

Amazon has a good selection too.

It's rotten luck. But I will say that I wouldn't trust my two existing 2 ton jacks to lift from either the front or rear hard jack points, somehow I just feel that it is asking a bit too much for them even though they are rated to lift more than what the car typically weighs. So when I had to do my thermostat replacement, I used both jacks to lift the front from the normal side jack points. But then this is risky working under the car without any jack stands, and stupidly unlike the E46 that has exposed frame rails that have hard points on the E90 all that you see is flimsy plastic covers. So I placed the jacks stands under the car in areas that seemed fairly solid (and pretty much resting on the jack stands lightly) so that if one or both of the jacks were to fail, at least I am not pinned underneath. Worked fine, but not at all ideal of course. I think one needs a good heavy duty 3 ton jack with a nice big and wide lifting cup, preferably with a rubber or similar footprint. Then once lifted let the jack stands hold the car's weight.

That's what's I'll think I have to get. I've seen people place jack stands under the control arms?? Never did fully understand that. I was thinking about just doing away with jacks and getting ramps as that seems more solid. Even if your jacks were to fall and the car caught by stands, I'd still crap the pants

I wouldn't put jack stands under suspension components either. I still need to invest in a good low profile heavy duty jack. Something that is nice and sturdy and tough enough to be trusted. Yep, trust me, I was super weary of working under there like this, but it had to be done, so not ideal, but got the job done. I reckon at the very least, some poo would have come out, if the jacks had to let go.

I was answering the question about the design considerations the engineers used to place the hose where they did (i.e. near the jackpoint). The car is mostly engineered to be worked on using a commercial car lift since that is where 90% of the cars are serviced, at a dealership or mechanics shop that used car lifts. Engineers also do not take into consideration that the jack being used on the front jack point is going to fail.

I agree, I was just pointing out that I wasn't being a dumb arse jacking the car lol
