[DML] Re: AC Rubber tubing

["sweetp01569" <paul.sweet@xxxxxxxxxxxx>]

Thanks for the great replies.  I didn't do the conversion.  It was 
done by the previous owner in March of 2004 (about a year before I 
bough the car).  The record shows he bought a $34 R134A conversion 
kit.  This doesn't sound like he replaced any major parts, does it?  
How extensive is a "kit"? I think I should probably change the tubes 
and major components that I am able to, then bring it to the shop 
for final tweaking and refilling.  Is that reasonable, or are there 
other items to be aware of when replacing components?

Thanks,

Paul
