Thread: 4.0L V6 D3 - Where is the front timing chain tensioner?

Do you realise that there are 2 tensioners, 1 for each chain? They push on the side of the chain, with one pointing down from above and the other pushing up from below.

Graeme, yes I do. I've already changed the one on the rear chain. Do you know where the tensioner for the front chain is located?

Sorry, I only have the parts catalogue which only shows the chain and tensioner parts, not any housings.
The tensioners should be in the same relative position on both chains, removing slack on the after-crankshaft side of each chain.

That's the guide against which the tensioner presses. I couldn't spot the tensioner itself in that diagram although it could be shown where it is on the housing in the cut-off bottom section.
Actually, isn't that the balance shaft and chain rather than a camshaft chain?
Edit: Wrong again - that's the jackshaft.

Here's an extract from the WSM showing the heads and timing chains which are driven off the jackshaft.
#27 on the head components diagram appears to be near the front of the left head (looking from behind the engine) on the inlet valve side.

Sorry, still trying to get the diagrams able to be opened. There seems to be a problem reading this file from here.

These are also from the workshop manual. Hopefully a combination between Graemes and these may help.

I can't open your files either but can save the links.
