Coolant drip top-rear engine 1.4 Petrol

Success!

Bit a a good nights sleep, advice & support from you, removed the cable at the bottom (clipped on the clip shown on the red circle in the above image), bit of a wiggle and its now free and removed.

My new question is re gaskets on the pipe.
The image in the parts list here https://audi.7zap.com/en/rdw/audi+a2/a2/2001-248/1/121-121030/
Shows gaskets 14 and 15, which I thought butted up against the end of the pipe, but I diddnt have them, certaily on the top.

Are 14 and 15 actually the gaskets that go round the outer of the pipe each end, into a recess? Thats where mine was leaking on the top as the gasket is looking a bit flat and hardended.

The most common coolant pipe on ebay shows those gaskets in situ, I guess I dont actually need to order the 14,15 seperatley?
 
Evening @Tomscar,

In reply to your earlier post I was just trying to get the state of play straight in my mind. Fully appreciate what you said about keeping the C clip in place both for removal (a better 'handle') and refitting ( otherwise near impossible to insert C clip).

Interesting what you said about the cable support (ringed above). It does not seem to be used on the FSI, at least on mine, and I just assumed it was that for some other engine that uses this pipe, you have me worried now that it should be used on my FSI. Maybe some previous mechanic with my car forgot to employ it or forgot about it until it was too late and ignored it! I assume you refer to the knock sensor cable, always thought it looked a bit floppy and near the block! Any other FSI owners care to comment?

Andy
Hi Andrew, you could be right there, I didn't check what the cable is attached to on mine but guess if there is something on the FSI hanging close to it that it might be good to clip it in just in case ???

Hi Carbore, yes that's right, they come with the pipe ... one end has a flattened 'H' profile and the other is an 'O' ring and both sit in a recess in each end of the pipe.
 
Part no on existing thermostat is 032 121110B which google says is an 87deg one, so 'ok'

Im making a list, and checking it twice.
Pipe + Gaskets
Thermostat + gaskets included
Housing (will need to use the the end part of the original as per @Tomscar s post earlier)
Gasket for the housing to block
Coolant (have already)

Hi again ... you're a busy man this morning? ... the housing will come with the thermostat and all the gaskets, including the one to the engine block, just double check when you order the housing that the thermostat is the same as the one you're taking out ... from what I can see the housing is common to the metal one and the plastic and the difference is in the cover ... it's more obvious when it's in front of you than me trying to explain it ?
 
The Topran Thermostat Housing 110350 is made as a direct replacement for the Audi 032121111AM at a fraction of the cost .... but mine came with the wrong thermostat installed and ended up buying a genuine 032 121110B and matching cover ... probably would have been a similar price just buying the genuine housing to begin with!!
 
Right, bits ordered so thats that on this job until after Christmas. Thanks for the help.

I am taking some notes and phots etc and will try my best to do an end to end write up on this (including several "dont do this" comments ;-) )

The 'don't do this' ... a great idea, good luck with it and will look forward to the pictures ???
 
Blimey, parts all arrived today!

Thats pretty good seeing as how I ordered about 12:00 yesterday and they all arrived from 3 different places in the post and by courier. Especially as I live a very long way down in Cornwall.

... all done by tea time ???
 
Well that was an epic struggle, did the whole thing TWICE (grrrrrr)

First time took a while as the top of the housing snapped off, new part was incorrectly ordered and as It was holidays and I could not source one I decided to fix it. Made a threaded insert from a bolt and looks good.

Next of I fitted the whole lot, tested it and it looked ok up top with no leaks. Overnight though the car lost a lot of coolant though. After much worry about my own work I totally pulled the lot apart and found a bit of flashing on the seal for the back tube (ARGGGH) I thought id cehcked for that nonsense.

Anyway as during this a cancelled order arrived of a better quality one (long story) I have now fitted that one and its looking more promising. Ill try to do a proper write up of the correct process, but its been a bit of a love hate battle over the Christmas holidays.

Hopefully thats it.

Hi there
I had exactly the same problem that you solved with the threaded insert - is this a hollow bolt that you used or how did you fabricate it?
Thanks
 
HI @BelleekBeetle sorry to hear of your trouble

For the insert I made it on a little lathe I have. It was a basic bolt that I turned down, drilled the center and threaded the end. I felt the threads needed to be smaller than the main shaft to get a seal. Basically I just used a bolt as thats what I had that was about the right diameter to start from, I could have used plain rod if id had some the right size. Note that I did make the sligthly phallic buldge on the end to push the pipe over, its not a straight rod. The insert was "self tapped" into the housing after a very carful drilling out if the snapped end to make a hole and then bonded in with gorilla super glue. It seems to be holding ok so far, but I dont do long trips and its not been summer yet etc.

Just a comment on the gear selection. I found that I didnt need to move any pipe work to get to the linkages once id got the hang of the twist method to remove. I ended up just adjusting mine by trial and error and didn't bother with the locking mechanism or any of the clever stuff in the YouTube video I think you mentioned.

In terms of the pipe, theres a lot in this thread about the issues, but feel free to ask any help.

Thanks for that Carbore - it is a very fine bit of machining that you did as it must be a fairly small bolt to work with but great work

I agree on the linkages - not that they are actually freed up I can move them easily enough and I think I'll try a few adjustments as you say as I am sure that there is a decent gearchange in there somewhere :)

I got a replacement pipe and U-clip yesterday so that will keep me busy on Saturday morning at least

Thanks again
