It's a good idea to clean off the cooler, especially the fins where crud keeps the air from flowing thru and doing its thing. The cooler is just aluminum; solvents won't hurt it. I sometimes take these to an auto machine shop and use their parts washer to wash it off carefully. While you're at it, there should be a piece of foam rubber covering the top of the cooler. The OE stuff has probably disintegrated by now, so you need something to take its place. I have precut pads that are just the right size and shape, and that have been tested to hold up to the heat and oil of that environment. They are $5, shipped. If you try to clean the top of the engine, try to find something to plug the oil holes with, so you don't slip and scrape sludge into one of those holes. THAT would be disastrous. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Shameless link for search engines: http://listarchive.type3.org ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
