brek7 Posted July 20, 2013 Share Posted July 20, 2013 So I re did my entire A/C system yesterday on my 98 Honda Civic. I replaced everything but the hoses. So that included the Evaporator/Expansion Valve, the Condenser, the Dryer, and the Compressor. I got new seals on all those areas, put a little oil on them bad boys, tightened it all up, and then drew a vacuum on the thing. As soon as I turn the vacuum off, the pressure returned to atmospheric. So, I thought I had a leak. Does anyone have any suggestions? The system has oil but no R-134a obviously. I used a little Autozone rental vacuum and gauges to pull the vacuum. It was brand new, but the gauges were not. Please help! I really haven't a clue now how to find if I do in fact have a leak or not. And if so, how on earth to find it.Thank you in advance! It's like 98 F today...

Aaron_wayne17 Posted July 20, 2013 Share Posted July 20, 2013 If the system is totally sealed as it should be, then even if something else were to not function properly it should still maintain the vacuum. If it's not holding a vacuum then there has to be a leak somewhere......it's just a matter of locating it. Link to comment Share on other sites More sharing options...
James Matteu Posted July 20, 2013 Share Posted July 20, 2013 LOL@Aarong @brek7 first look overyour work, make sure you didn't miss anything, or that you left anything loose. then put a little refrigerant in the system (like 1/2 can)and make a mixture of soap and water, use the water soap mmixture to look for leaks; lleeks will appear as bubbles.
