Only when it is 100 degrees outside! The continuing saga of cooling an '88 in New Orleans. Yesterday I was troubleshooting my AC system. The compressor was cycling off despite 100 degree temps and 95% humidity. Vent temps around 75 degrees. After adjusting my evaporator probe placement and testing coolant pressure, I decided to add a half can of R 134. The engine and garage were both super hot but the pressures weren't in the red so I put a half can in and KAPOW!!!! The Kuehl hose that connects the compressor to the deck condenser blew right out of its crimp!!!! Talk about a massive messy explosion. Gladly my face wasn't near the area because r134 and oil spewed everywhere. UGHHHH!!!!!!!
The hose / crimp is out of warranty of course
I have been replacing this system bit by bit with Charlie Griffith's parts for years, but I can't afford the labor involved in adding the 2 additional fender condensers he suggests. I already have a new denso compressor (twice), replaced hoses with all Kuehl barrier hoses, new blower motor (twice), Kuehl hurricane evaporator motor and squirrel cage and box, and extra vents.
I guess the last intermediate step I am going try is to buy a new Kuehl front evaporator and Kuehl front and rear condensers. Another 1600.00 bites the dust - hopefully I can do all of the install myself and just have my wonderful mechanic Mike Nausourra (thanks user #drjon4u2) recharge the system at the end.
