Asked in Toyota 4Runner
What kind of refrigerant used in a 1991 Toyota 4Runner?
The 19914runner used R12 and is very expensive to buy and has to be installed by a licensed tech. The answer is to switch to the newer 134a type. You will have to buy the 2 conversion valve ends ($20.00) and you have to evacuate all the old out first, this has to be done by a pro with the right equiptment. Then refilled with the 134a type coolant and a can of oil for it. I did the whole thing for a friend, I replaced the pump on a S10 then refilled it but found out later you need to be licensed...oops I didn't have any idea but it works so there ya go :)
