Can you use the r134a freon in a 91' S10 Blazer... I bought a can at advance auto and the install hose on the can will not hook to the low side port... Or do you have to have it professionally gassed up...?? Thank you all for helping me thru the new motor install....

 

well do you have 134A fittings on the truck? and also do you have the right oil in the compressor for 134A

i got my truck converted to 134a since they dont sell R12 freon any more .

 

No it does not have the r134a fittings on it. I thought there might be another hose i could buy to gas it up... But you can have them changed over to the new type?? I have never had to have that done before.. Whats has to be done to change it over?? can i do it myself??

 

well i never changed them . i had a mechanic do it . they charged me 200 bucks for the fittings oil and filled it up for me

Edit: i didnt pay for it to be done a friend of mine payed for me by force . ill get him back for that

 

advance sells a conversion kit for $50 I think it just screws onto the old plug

 

I did get a hose with the can i bought but it did not fit. I have never worked with the old style before. Do i have to change out the compresser and lines to change it over to the new r134a?? It is definitely is the old style... Can they still be gassed up???

 

well when the mechanic did mines they changed the oil in the compressor for 134a and they also changed my fittings from r12 to 134a . then they filled her up

 

Cool, That dont seem so bad. Thanks a lot for all your help... I will check into getting that done...

 

good luck
