I'm planning on cleaning out the intercooler on my 06 Freelander 1 Td4. Quite a large amount of goop inside. I've read all kinds of horrors on Facebook about putting petrol through, is there a touch safer way of doing it ? I'm thinking after how badly the previous owner treated the car (They seemed to be in the belief that Landrovers don't need servicing ever) I might bin the stock intercooler, replacing it with something better or just clean it out.
