Cleaning the intercooler
I am going to replace the intercooler pipework on my CDT.
Thought while I am at it I might just give the intercooler a thorough clean. Is there a way of cleaning out it's internals to remove all of the oilly deposits? Is there a product to run through it? Also the fins on mine are full of years/miles of crud. What is the best way of cleaning this out? Would a jet wash be too harsh? Thanks in advance Chris

I use petrol, remove the intercoler and 3/4 fill with petrol and leave for about 15 mins then shake the cooler to clean off the oil/carbon deposits then empty and leave outside for a couple of hours to vent, obviously take the usual precautions when dealing with petrol and do it outside!

A jet wash would likely destroy it
To clean out the intercooler any de-greaser can be used gunk,parrafin, etc only way to do it properly is to remove the intercooler so it can be washed out and drained completely. Good opportunity to check the overall condition as they have a bad life down there and while it's full of de-greaser it'll show up any holes If it does have problems then replacements aren't telephone numbers financially, as long as you don't go to Rimmers or X-part

Thanks. I don't tend to have any petrol around, but I guess I could fill a can. How much does it take to 3/4 fill it? What would I do with the petrol after I've used it to flush it out? Once again thanks Chris

Was thinking a jetwash wouldn't be a great idea but I do remember noticing how full of crud the fins were. Is it simply a case of soaking it carefully cleaning it with a stiff brush and some warm soapy water. I probably won't get it done 'til the summer when I can have it all apart for a full day without having to worry about having to use it. Found a company that makes an upgraded one with the connecting pipe welded on, so no leaky rings. http://www.gm-radiator.com/?page=sea...&spartno=71039 Might email them for a price, just in case.

You can get away with using a jet wash, if you do it from a distance.

That resulted in the decision to "uncrimp" that end from the matrix so that we could inspect inside then weld the plastic with a soldering iron followed by a coat of "real steel" epoxy inside and out then a bead of "adhesive silicone" round the lip of the end tank and crimping the "tangs" back in place gave us a nice airtight repair!! You can store the brake cleaner and the solids will settle out so it can be reused later - plus it wasnt very mucky inside the I/C anyway (really clean after the wash out as we found it pretty spotless when we got the tank off) even though the air leak had resulted in a build up of oil on the parts round the end tank bad enough to eventually drip on his drive which was the original reason for the removal and strip down!! - similar to having the "o" rings leaking but lots more of it I guess Be aware that the intercooler has a 1 piece tube running across the lower 1/3 of the I/C ie- just that a single big hollow tube rectangular in shape and that the upper 2/3 are the return to the feed into the intake manifold and thats the section with all the small diameter tubes in like a radiator!! I assume that the lower section has a sort of "pre cooler" effect with the final drop in temprature happening in the top section on the way back out!! I wonder if there is room for improvement/tuning here? Quote:
Followed the link!! I like that idear !! if you contact them could you enquire if the are ally or steel and what the surface finish is? all so are they an up-rated unit in that they have more cooling area/effect or are they just a replacement for the standard one ?? plus a price of course!! and update us please?? Cheers! Andy |
