Hei all! We have a Defender 110 300 tdi from 1995. It's intercooler needs flushing/cleaning. What is the best to use? Is it ok with pure and clean gaoline or should I go for anything else? Regards Lesja, Norway
at what intervals should this be done [I have 106k on the clock and I have never cleaned out the intercooler] and will it make any noticeable difference?
I cleaned mine out at about 110k miles, it had about a 4mm thick layer of crap in it!
Dunno if it made a difference as at the time I also junked the EGR, added new intercooler pipes etc etc ...
I should imagine cleaning at 75k would be reasonable and would give a noticeable benefit, judging by the volume taken up by the crap ... it must let the engine breathe more easily!
