TextTextWell I will cut to the chase. I bought a conversion kit at Kragen Auto. The conversion kit was interdynamics brand. I followed their directions to the letter. I had cold air for about one day. They following day I found out that the r134a leaked out the low end valve. Almost 3 12 oz cans gone. Thing was it worked fine for about a day. I want to change out the valve cores on both the high end and low end. What do you guys think of the kit offered by Honda: 38020-Sm4-A1AH ? Does it include the valves? Steve in Hollister, CA

The Honda kit isn't much different than what you purchased from the auto parts store - both are inadequate. At least the Honda kit notes the importance of recovery and evacaution prior charging, and monitoring high and low side pressures. But PAG on a retro? Not a great idea.

In short, you're going to need to thoroughly flush the system, replace the receiver dryer, all o-rings, upgrade the condenser, and perhaps increase fan capacity, refill to spec with POE oil (not PAG), vacuum and charge, and do a little tweaking with both the charge and pressure switches. Anything less and you'll pay a penalty in cooling performance, or possible damage to the entire system.
