I posted this last year, heating season is here again. These are big cracks, a tiny one you would not be able to hear would still be dangerous. These are not accident damaged. If you have a set on your car, grab the carbon monoxide detector from home and take a ride with the heat on and windows rolled up. There is a detector used in small aircraft also available. The last photo is how we now test for leaks using air pressure. Brad

I found something similar on a pair of factory bus heat exchangers, though those have a cast aluminum heat sink around them and are steel. I had the sheet metal off of them. I put a rubber stopper in one end, modified another stopper with a cut-off a bicycle tube air valve stem for the other end. I submerged it in a rubbermaid-type container. Using a bicycle pump, there were numerous tiny cracks, fissures difficult to notice by eye that bubbles easily came out of.
Bus ones also have asbestos fiber lining all inside the sheet metal but that's another issue. (IMG:style_emoticons/default/blink.gif) |
