nickwilliams Posted April 19, 2010 Share Posted April 19, 2010 What is the forum's recommendations for cleaning and flushing the radiator and intercooler matrix before re-fitting? I reckon it will be at least a month before I get to put the intercooler and rad back on my chassis. At the moment they are sitting on the floor of my workshop getting in the way so if there was some benefit in having them full of something which will help clean out the innards, now would be the time to do it. Thanks Nick. Quote Link to comment Share on other sites More sharing options...
jbs Posted April 19, 2010 Share Posted April 19, 2010 The intercooler I would flush out with brake and clutch cleaner-you can get this in gallon can's from a auto parts suppliers and this thread on the tech archive http://forums.lr4x4.com/index.php?showtopic=10449 Hth John Quote Link to comment Share on other sites More sharing options...
Orange Posted April 20, 2010 Share Posted April 20, 2010 If the vehicle has a history of being used in mud/muddy puddles, I would also take the opportunity to leave both rad and intercooler submerged in water for a few days to clean between the fins. Leave to soak for a day or so, then a quick blast with the pressure washer (or hose with your finger over the end), then leave to soak.....repeat a few times and it'll soon have the fins clear!

shanghai1979 Posted April 22, 2010 Share Posted April 22, 2010 Solvent in the inter-cooler. I used acetone (nail varnish remover but about 1 liter). For the rad back flush it with lots of water. LRO did an article a year or so ago on this. Quote Link to comment Share on other sites More sharing options...
