Arjan Posted July 15, 2018 Share Posted July 15, 2018 I have several Intercoolers (200 & 300 Tdi) that have oil - lots of oil - in them. What is the best way to clean them and making sure there is no resedu left that could / wil harm the engine once fitted again ? Thanks Quote Link to comment Share on other sites More sharing options...
Daan Posted July 15, 2018 Share Posted July 15, 2018 fill it with brake cleaner, close of the pipes so it wont dissolve. Leave overnight . Drain and flush with water. Done. Daan Quote Link to comment Share on other sites More sharing options...

miketomcat Posted July 16, 2018 Share Posted July 16, 2018 White spirit would work too just give it plenty of time to dry out. Personally I wouldn't bother with water. But only because I don't usually have time to soak it overnight let alone leave it to dry. Mike Quote Link to comment Share on other sites More sharing options...
JohnnoK Posted July 16, 2018 Share Posted July 16, 2018 If it's the usual Landy problem of being well oiled, then I'd toss in a liter or 2 of petrol, slosh it about to dissolve the oil and then throw it out. Then, mix up a batch of dishwash soap and water and fill it to soak for a while, drain and partially fill so you can slosh it about to move the soap through the fins. Finally, rinse with water.

monkie Posted July 16, 2018 Share Posted July 16, 2018 Another vote for white spirit. What ever solvent you use make sure all the residual fumes have evapourated before refitting. Don't be tempted use anything caustic as a cleaning agent on aluminium parts. Quote Link to comment Share on other sites More sharing options...
daveturnbull Posted July 16, 2018 Share Posted July 16, 2018 I tend to use paraffin for cleaning inaccessible oily bits, mainly because I had some and it's cheap. Not tried it on an intercooler, but seems to work well on other stuff.. Quote Link to comment Share on other sites More sharing options...
Jon W Posted July 16, 2018 Share Posted July 16, 2018 When putting it back on just run the engine with the bottom hose connected, then it is dried out with the air passing through it and nothing will end up in the engine Quote Link to comment Share on other sites More sharing options...

Simon Smith Posted July 25, 2018 Share Posted July 25, 2018 I half filled mine with Jizer, sloshed it about for a while, emptied it and flushed thoroughly with water. Then I put the breather into a catch tank so it didn't get filled with oil again. Quote Link to comment Share on other sites More sharing options...
Cornish Rattler Posted July 25, 2018 Share Posted July 25, 2018 (edited) I normally fill them with petrol and seal the necks up and leave them for 24 hrs then empy it out and iff need be refill it and give it a good shake then empy it out again and leave it outside to vent, the last one i did i used a full tine of Tornado RC fuel that cleaned it out Edited July 25, 2018 by Cornish Rattler Spelling Quote Link to comment Share on other sites More sharing options...
