anyway, i will attempt to replace the tensioner after office hours... it's an 87 300TD... from what i've read so far this is the gameplan:
loosen shroud to access the FAN
somehow stop the fan from rotating...jam the belt at the power steering pulley?
(replacing the belt anyway)
remove fan with an 8mm or 10mm allen?
remove belt...
remove PULLEY from tensioner before removing tensioner...
remove tensioner using what? 12mm hex?
i have to be absolutely sure about the sizes because i will have to buy these... my tools are at home...
thanks
