so this is my 1.6 HDI engine so I decided to clean the intercooler and the
intercooler is down here, it is a bit dark, I'll put some more light, so
basically the crankcase gases with a bit of oil vapor go through turbo get
compressed and oil gets pooled or there is a film of oil in the intercooler so
it looses its efficiency, so I decided to clean the intercooler, so these two pipes
needs to be removed in order for the intercooler to be taken out potentially
that turbo pipe also needs to be swung on that side so for the
intercooler - to be replaced so I'll start with with these two pipes
next thing is to remove that joint and
that now one needs to swing open otherwise cannot get out, so in order to
swing this there is a bolt, hex bolt that doesn't need unscrewing only this one
from that side and then this really swings open, it doesn't even need a lot
we can actually swing it. Well is has to be undone actually completely and then this
can can swing, there we go, it swings completely open there is a
catch on that side so this swings open so we can leave it as it is and see
what can do with the other ones. There is a bit of a oil inside so
this goes into the intercooler and pools down so that's why it needs cleaning and
and here as well and can't quite be seen but there is a bit of oil as well
Next is to remove this one, seems a bit on the tight side
this one's out of the way next there is a, can't quite be
seen but there's a bolt, I'll show it later, that there is a bolt here that needs
to be taken out so that's the bolt that needs to be undone, these are kind of in
the way but is a I'm not too sure, I have a tool but it's pretty difficult to undo those
but I'll try to do these as this needs to be, the rubber part needs to be taken
out otherwise it's a bit difficult to maneuver the intercooler out so the
problem with these is actually they are fairly tight here so I cannot really unscrew them that easy
so I have a 10 mil, 7 mil for those with a slight extension, so I can
grab this with with pliers and try to turn it hopefully it'll work otherwise
it's it's pretty difficult to do it's not difficult but it's slightly tight
let's see how this goes
I can't even, it's pretty tight space actually
so it did not work with the pliers, I have a small spanner on this end see how this
goes hopefully it will rotate, started rotating
finally
finally and there is I mean the light doesn't, there is a bit of oil inside the
intercooler as well um it's only slightly oily but I can see quite a bit
of oil inside so then to the next one so the second one is pretty difficult to
get to, there's very little space so I decided to undo the bolt of the
intercooler then move this slightly forward and I probably have access to
that one
so there's a washer and a rubber kind of spacer, so this really needs to be pulled
out like. It needs to swing basically forward and then you can kind
of take it out, it has seen better days
so the next thing is really to lift the alternator, the intercooler, not the alternator
so there are a few pipes in the way and that is definitely in the way but so it turns
out that the intercooler cannot be taken out that side it has to be dropped
inside underneath and then pulled underneath, but I do have a metal
support underneath under tray which I need to remove so you have to remove the
under tray in order to be able to slip it depending on what kind of tray you
have underneath so I have removed the under tray so now the whole thing can be taken
out and slide it underneath I have not raised the car, so I'll see if there is
enough clearance to do that, I think there probably is, I dropped it a bit
here is underneath
there is enough clearance and that's the intercooler. I have not broken it when I dropped it, I haven't
broken really anything underneath so let me can get a torch, so with the torch
you can't quit see, there is a bit of oil there this is the intake this is the out
there is a bit of, there is actually quite a bit of oil
so tip it to see if I can, if there is any oil that has pooled at the bottom, so the
next thing is to clean the intercooler so I'll tip it to see if there's
any oil inside, but it's only a film, it has not pooled down at the bottom
It's only probably a film rather than, so there is a bit. What I'll do for cleaning
using acetone, it's for nail removal so what I'll do, I'll really pour basically half
a litre inside, then I'll put one of these
nylon things with a rubber band so and then shake it from side to side
That's generally it and I'll tip it in a while
what's inside okay, let's tip it over
it's quite a bit black
and quite a few bits and pieces black pieces
Let's see what's inside, so here that's from the, quite a few black pieces here and
there but it's definitely a film but not really that much oil, so I'll do another course of
course with acetone and then let it dry for a bit pour water inside to clean it
to clean the residues of the acetone and then with a hairdryer
from one side so everything to evaporate
so second second time pouring, a bit cleaner much cleaner
much cleaner
so I'll do the same procedure with water and then the hairdryer from one side to
evaporate. And final step is really to blast it with a hairdryer
so I have one that I can stick in there and initially cold air and then hot air to
see if it is gonna blast something out
it's coming out, yeah
like that until it it's completely dry I
The intercooler is squeaky clean, not squeaky clean but fairly clean, I blasted it
with quite a number of times with with water there's probably a bit a drop or
two of water inside but that probably is not too crucial, the acetone was more problematic
I have really cleaned very well with soapy water so they are both quit clean and
feed it from underneath basically the reverse procedure that I think it's the
thing here I think it's 25 Newton meters with a bit of oil on the seal
just to make it tight everything in reverse order and that's it
hopefully it is of any help to anyone and that's how you can clean the
intercooler thank you for watching
