Default Dismounting DENSO compressor from engine body

How I can dismount DENSO air-conditioner compressor from engine body..

The car is Audi A6 2.5TDI 98/12

compressor is mounted with three bolts to engine corpus(body) removing theese bolts is easy.
the problem is how I can deinstall and again install belt which operates compressor washer

basically think this is related to overall question how I can deinstall and install new belt of engine... i.e timing belts, compressor belt etc.

Default That engine never came to the U.S., and this board is primarily a U.S. audience.

Someone might have your answer, but if I were you, I'd be looking for a good European Audi forum.

Default So, you want to remove the compressor, but still drive the car?

The 2.5TDI looks to have two serpentine belts, one of which runs the compressor, and one that runs the rest of the components. Just leave the compressor belt off.

To remove the belt, it would appear that you would remove the protective cap from the tensioning roller and the remove the roller, which will allow you to remove the belt.

yes, thanks for reply.
I figured out how to remove it.. there is cover cap on bottom cover of engine timing belts.. and inside there is bolt which is used to change tension of compressor belt. then you need to remove three bolts holding compressor to engine body.. idea was to remove faulty electro-mangetic muffle without releasing freon in athmosphere... then removing muffle is easy...

it is kind of tricky work ... because you need to do all that stuff below car itself

yes that engine is very popular for audi owners (like me) in europe ... because here there is big difference in cost of gasiol and gasoline... gasil is around 50% cheaper than gasoline... also include that Turbo Diesel (TDI) engines consume alot less fuel then Otto-motors for sample your 1.8T or 2.8 audi have bigger costs per mile than TDI ... also latest generation TDI engines for sample newest 3.0 common rail TDI engine of audi has similar acceleration params as 3.0 gasoline engine... and you will see difference... at least for european owners

Default Yes, but then you have to scrub all the diesel soot off your beautiful buildings!!

As much as I think diesels are interesting, I think their popularity in Europe (and lack of popularity in the US) is largely because of the taxes you pay (or don't pay) on fuels.

20 years ago, diesels offered much lower maintenance and (in the US) a cheaper fuel cost. Now, gasoline engines are low maintenance and diesel is more expensive than gasoline (if you can find it).
