Quite possibly true Turbodiesel. I'm a big fan of PM and replace everything that I think might fail as I drive in some tough country myself. At 250Kmi I replaced the vac pump, tensioner, fan clutch (earlier I had replaced the t-stat, upper and lower rad hoses, and a host of other things). After a two week "burn in" I drove out across SD, WY, MT, ID, UT, NE, ... Its just that I've heard the factory pumps will outlast virtually all the replacements (even dealer rebulids). I've also heard that Laso pumps are not as good as Graf. Which kind did you install?

Regards,
