- Petrol Jimnys have an auxiliary belt (fan belt) and a power steering belt.
- There are a number of combinations and it is essential you get the correct belt.
- Diesel Jimnys have one auxiliary belt which drives all auxiliary engine devices.
You should not purchase based on guidance below - you should identify the correct belt for your vehicle elsewhere.

Tensioners for Jimnys 3
There basically two types of tensioners for petrol Jimnys 3:
- One with a small center;
- These are more common on the G13B engines;
- One with a large center;
- There are more common on the M13A family of engines;
You should not purchase based on guidance below - you should identify the correct tensioner for your vehicle.
Small hole tensioner
- This is Suzuki part number 49160-82A00.
- If the bearing has worn, then it can be replaced by pressing the old bearing out.
- A suitable bearing is available in the BigJimny Shop HERE
Large hole tensioner
- This is Suzuki part number 49160-81A00.
- This tensioner is commonly called a "smilely tensioner" because of the appearance.
- If the bearing has worn then it can be replaced by pressing the old bearing out of the outer rim and pressing the smilely centre out.
- A suitable bearing is available in the BigJimny Shop HERE
Replacements
- First of all, the BigJimny shop has a high quality replacement bearing for sale (read above).
- However, if you for some reason want to replace the entire tensioner assembly (generally a lot more expensive), you can either buy the original Suzuki P.N. 49160-81A00, or one of the aftermarket tensioners.
- Example aftermarket tensioner is SKF VKM66009
- By the way, the bearing which Suzuki originally installs in this tensioner is NSK 6010DU2 (that's at least the case in M13A engined Jimnys made in 2013).
- That bearing has rubber seals on both sides.
- Specifications are: single-row, ball bearings, deep groove, 50 x 80 x 16 mm
- NSK has allegedly superseded it with the bearing model 6010DDU.
- However, since the specifications of those two bearings appear to be the same, it could very well be the same bearing, but just a changed naming nomenclature.
- There is also a "premium" edition of this bearing.
- It is NSK 6010VV.
- The "VV" suffix means that is has special "contactless" double sided rubber seals (and made of some super tech rubber), which effectively allow far higher bearing RPMs and operating temperatures.
- However, this premium bearing is about 3x more expensive than the "ordinary" one.
- This premium bearing may be an "overkill" for this application (in other words, the standard bearing may be sufficient), but an expert should give an opinion.
- However, if someone wants to indulge themselves with this premium bearing edition (instead of using chocolate or sex dolls for a change), then buy NSK 6010VV.
