WHAT IS THIS?

Yea you will need to get a new hose and the have the ac system recharged. I would recomend that you do a r134 conversion at this point so it does not cost you an arm and a leg to chage the system back up. Just dont go to auto zone and buy a can of crap and try to do it yourself never works out

dude, dont know about you guys but when i took the truck apart that damn refrigerant had a fucken bad smell to it. and the charcoal canister has no fluid unless the wrong line was hooked to it.

where can i buy a new hose? and how much would it cost to have the r134 conversion done? thanks

new hose from toyota parts dept. 134a conversion should be around 50 bucks.
