I decided to dig just a bit further down into why I was not getting nice cold air from Polei (sdl)
I had primed the systems with some mineral oil and a can of air duster a week or so back. That stuff had worked for Allen, but the compressor would not kick in. There was equal pressure on the high and low sides of 70 psi. I checked the aux fan, and it would run with 12v. That is good. The Klima got pulled and I jumped pin 7 to 5 which kicked on the compressor clutch. I figured that was a good time to hook up the manifold gauges and see if I could feed more canned air. With the compressor going, I could feed another 32 oz. Then I got to seeing some little mist and hearing the rush of gasses. Poop! That means I need to go looking for the UV lamp.. in broad daylight. I quit charging and let it piss away. With enough time, the dye began to show. Seems there was a hole in the receiver/drier. I am guessing I will need to flush the system bits that need it and replace the can. Should I just as well replace the pressure switch and temp switch? I have some AC Delco 525 mineral oil on order. That should be a nice addition to the drier instead of the lame FLAPS oil. clay 1974 450sl - Frosch - Two tone green 1986 SDL - Polei 1982 300 SD - Allen retired models- 2002 s430 - Victor, a Stately & well tailored crap 1976 300D - Blei Vanst - it looks silvery 1972 220D - Gump - She was green, simple and ran 1995 E300D - Gave her life to save me against a Dame in a SUV POS 1987 SDL - Beware Nigerian Scammers _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
