Re: [DML] Aircon failure plus R134a capacity query



Chris,

You might have already checked this...  If the high pressure hose is  
not secured, it will rub against the steering shaft and eventually  
rupture.  Be sure you don't have a hole in the high pressure hose in  
the area of the steering shaft.
