I have a 305-70-16 on my stock 99 f250 diesel.
No
take out old one and put new one in
R134a
There should be 2 ports on your ac lines 9about size of dime) that work like tire valves. You just plug in a can of r12.
It does not contain Freon, it contains R134a refrigerant. Put it in using the low pressure connection.
The 2003 Ford f250 did not come with an air cabin filter. There was a dealer install option but very few were ever put in.
Do this with the engine cold. At the base of the neck of the top radiator hose there are two bolts. Take those two bolts out and the thermostat is right there. lift it out and put the new one in. Then put the radiator hose back on and check the coolant level. I just had to do this on my '89 f250.
Dead Battery. Are you sure your battery can maintain or hold a charge?
Yes you can
I have a 2002 F250 that had the same problem. It turned out to be a short in the wire coming from the cruise control on the shift lever.
Where do I put freon in a 2007 chevy impala
