Kingnuggie how hard is it to remove my 240 wagons evap unit, where would I get a used one from?
is it a dash out move or can you sneak through the glovebox?.............
the mechanic said it needs replacement, is it easy to work this out myself?
Oh and finally is a 1991 the old gas that i have to replace with propane or the new gas that does not work very well but saves the environment?
PS
this forum is awesome
The old R12 gas was roughly 1000 times more powerful than carbon dioxide as a greenhouse gas, R134a which replaced it, and is in widespread use, is about 100 times more powerful than carbon dioxide.
There are genuine Volvo and aftermarket conversion kits to use R134a in earlier models, they work well as they include a TX valve calibrated for R134a.
You can also use a propane/butane type refrigerant, they work well but are illegal in some places due to fire risk. It doesn't take a big impact to puncture the condenser or hoses at the front of the car, releasing the flammable gas and greatly increasing the risk of fire. Personally I will never use it in my cars, but each to their own based on personal risk assessment.
I should have a used evap core from a system that was known to hold gas at the time of removal, if you haven't obtained one yet.
