Would anyone have the part numbers of the 3 x new tensioners (with preload spring) or are they the ones listed on the Pelican website?

The IMS to crank chain tensioner "paddle" has a black wear pad on it's small end. It's about the diameter of your smallest fingernail. This is what the IMS hydraulic tensioner contacts to press the paddle against the chain. If you remove it & look into the hole it is centered in the hole, when new it has a curved surface, but flattens as it wears.
Pelican has all the tensioners listed, the updated IMS version with the preload spring was phased in during 2001, so it is listed as 2001-2004. It can & should be retrofitted to earlier engines also. With the engine locked @ TDC the 2 lower tensioners are easy to R&R. The 4-6 cyl tensioner is not since you have to remove the A/C compressor & P/S reservoir.
