The current PN is 12831-85FA7, so it would have started as 85FA0. After about 85FA5, there has been no change in design, it's just been a change in PN to commonize use with other applications.
As we never had the 2.0 V6 in Canada, I can't confirm the PN, but based on the design, it's most likely the same as our 2.5/2.7.
The new design has a much finer ratchet, so it does not have to extend as far between adjustments. The net result is the chain does not have a chance to slap, which is what causes the wear and stretching.
Yea Tim, thats the part number of the tensioner I have here. Unfortunately I have just realised that instead of having 4 bolts going up through the oil pan into the timing cover, there is two bolts in the centre, and the two on the outside are studs coming out of the timing cover through the pan!!!!
Arrrgghhhhhh. TIme to take the sump off.
Now I am used to working on Alfa Romeo's which if you ever have worked on can be a real bastard, but I reckon the guys that designed the alfa must have helped the suzuki designers now!
Well I did the engine/oil flush with some stuff in a blue can, remember the old oil cans that required a church key?, that smelled suspiciously like acetone. Read the label and that's what it was, mostly, with some petroleum distillates thrown in. Think I'll try the ATF next time. I'll run it for a day or two, flush out the oil again and then try some genu-wine synthetic or synthetic blend. Any recommendations on that? My little 99 GV has a little over 106K on it.
Its good to see someone else having as much fun with thier tensioner. I did my daughters a little while back. Here is a link to the thread and I put a little how-to together (its in my signature spot).
Yes I did see your excellent description of your tensioner repair. I wouldn't so much call it "fun" but more like "character building"!
The left hand rocker cover on mine was leaking at the back so had to take off the throttle body and inlet manifold to replace the seals. Pretty easy stuff luckily.
Did you find the old tensioner was a lot different to the new one you put in? Mine is out of a 2l 1995 motor so there is quite a bit of time between when that was designed and the current tensioner which fits all the suzuki v6's ( but not sure if it fits the latest grand vitara).
