Thanks! I have the manifold gauges and a pump to do that!Not sure on cost, you would more then likely take it to a shop unless you have the tools. You would need to recover the r12 from the system and replaced the drier and orifice tube. Also any o rings that are in bad shape, flush the system out then pull vacuum on system and charge it.
Not a bad price, that was including labor or no?I just had my 92 swapped to R134a 3 weeks ago and it only cost $215.00
Where ever you are finding straight R-12 at 10 bucks a pound is loosing money big time... R-12 goes for about 30 a pound and about $1000 for a a 30 pound unit... you can get "freeze 12" for about 10 bucks a pound but that's no where close to being real "R-12" ....I have converted several classic cars from r-12 to R-134a. I recommend staying with R-12. You can take an open book test for an R-12 license and I usually pay around $10 per pound of R-12.
If you do convert to R-134a then the single biggest factor to a successful conversion is the condenser. I always mount the biggest parallel flow condenser that will fit. You can buy a hose crimper tool for around $100 and then sell it when you are done). You don't have to change the hoses, but R-134a will leak through the old-style hoses. I usually budget $100 for barrier hose and fittings. I always replace the compressor with a new Sanden unit but you're in a better position to decide if yours is going to be good enough. Expansion valves (or orifice tubes) are cheap and you might as well replace it - you are going to have to take it off to flush the evap anyway.
The process to convert is well-documented but you have to flush the entire system of the old oil, add the correct amount of the correct oil, vacuum it down, then refill according to the pressure chart.
Whats this "freeze 12" that youre talking about? Alternative to R-12? If so how does it perform compared to r-12 and r-134?Where ever you are finding straight R-12 at 10 bucks a pound is loosing money big time... R-12 goes for about 30 a pound and about $1000 for a a 30 pound unit... you can get "freeze 12" for about 10 bucks a pound but that's no where close to being real "R-12" ....
But if you are getting real R-12 for 10 a pound. Buy it all and resell it.....lol...
