Hi folks,
I know enough to be stupid about stuff, so I apologize in advance for said ignorance. I've been told I need an A/C Hose and new tensioners for belt replacements (all of them). I need to order them, but I'm not confident I'm finding the correct parts.
Anyone point me in the right direction?
Thanks alot.

To aid you in looking up what Spook is talking about and exactly which of the many A/C hose or connector tubes may be needed, you can refer to the following parts schematics for a '94 940
1994 Volvo 940 Air-conditioning (usparts.volvocars.com)
That's for a non-turbo. If it's a turbo, I believe there are slight differences in the A/C mounting, so one or two of the A/C hoses and connectors may be different.
You can click back in the vehicle selector heading in that web page to re-select the correct model or other vehicle systems and components. There's a parts search field where you can enter part names or part numbers (you need to be careful as Volvo part naming conventions aren't always what we commonly talk about). You may need to visually identified the correct assembly in order to locate a part. Not all parts shown are available for selection, let alone being stocked. Once you've brought up the individual part, you can click on the Fitment tab to verify the various models the part belongs to, which is a great help when sourcing used parts from donor vehicles.
As Spook also alluded to, we'll need some clarification as to which tensioners you're talking about in order to help.
If you're talking seat belt tensioners then it's exactly as spook Spook said. Your only option may be used. Depending on the circumstances and your jurisdiction, you may need to be careful about documenting the source, installation and the possible need for inspection when replacing critical SRS components such as airbags and seatbelt assemblies after an SRS deployment
If you're talking about drive belt tensioners (alternator, power steering and A/C compressor), I'm curious why you would need to replace them all. It's common to periodically need to replace the accessory rubber mounting bushings at the tensioner brackets, also to replace missing or broken adjuster screws, or even the odd tensioner assembly that may have gone missing.
The only other tensioner I can think of is the timing belt tensioner pulley, which is indeed a wear item that should be periodically replaced in conjunction with a new timing belt.

Thanks again for this thorough info. I'm definitely referring to the Drive Tensioner Belts. I was told that if I tried to replace those belts that the tensioners are so rusty, that they'll crumble / break / crack, so I should have those parts ready to go. If and when they break apart when trying to get to the belts.
But it may be just be the adjuster screws that are in danger? And the other components you're mentioning?
The ultimate goal is to replace the belts themselves, but all the stuff to get to them is all rusted out and so that's the stuff I need to have on stand-by:
the accessory rubber mounting bushings at the tensioner brackets and adjuster screws, or the tensioner assembly all separate product numbers?
And thanks again!

Dear 92Volvo240,
Hope you're well. Thanks for the explanation. Before ordering a pile of parts, get a can of penetrating oil, e.g., Kroil or PB Blaster.
Before applying, use a wire brush - best used in a Dremel or similar hand-held rotary tool - and remove as much rust as possible from the screw threads and all other surfaces. Get down to bright metal, if possible.
Then, use penetrating oil to saturate the adjusting screws and lock-nuts. Do this for a few days, with multiple applications per day, if possible. It takes time for the oil to find micro-channels in the corrosion. That weakens the corrosion bond.
Then use a wrench or socket to apply pressure as if you were going to tighten the screw or locknut. Be gentle! Sometimes a micro-movement - after penetrating oil has weakened the corrosion bond - suffices to free the corroded item. Finally, reverse direction so as to try to loosen the screw or lock nut.
With a bit of luck, you won't need any new parts. Once you've freed each adjusting piece, clean-off all rust and apply a thin coat of white lithium grease. This will keep rust from re-forming.
Hope this helps.
Yours faithfully,
Spook

Thanks! And I will do. But just in case, let me confirm with you the replacement parts:
1) For the A/C Hose (A/C Refrigerant Discharge Hose
Part Number: 6848308), I'm looking for #20 in this image:
https://parts.volvocarsathens.com/a/Volvo__/42878455__5694437/Air-conditioning/GR-63214.html
Does that Part number get me #20?
2) Tensioning Arm Power Steering (Part Number: 1346897)
In this image, I'm looking for the bolt just below #10, running parallel and the smaller one that threads into the Bracket
https://parts.volvocarsathens.com/p/42863112/1346897.html
3) Tensioning Arm. Alternator. BOSCH. COMBU. Generator (Ac).
Part Number: 1378789
https://parts.volvocarsathens.com/p/42863110/1378789.html
THis one, again, I only need the bolts, but maybe I can only get them by purchasing the entire component?
4) And same for this one:
Tensioning Arm (AC).
Part Number: 9146231
https://parts.volvocarsathens.com/p/42863114/9146231.html
Again, thanks for all the help!

Dear 92Volvo240,
Hope you're well. It is best to call a Volvo dealer, and ask a parts specialist to confirm that a specific part will fit your car. Volvo often changed parts and kept records - using the Vehicle Identification Number - as to where one part was used, and whereafter another part was used. Volvo dealers' parts experts have this information.
Volvo dealer parts experts can also tell you if - in the case of drive belt tensioners - whether a single part number covers the tensioner arm, the tensioner bolt, and the lock nut, or whether these items have to be ordered separately.
My opinions in these matters are of no value.
Hope this helps.
Yours faithfully,
Spook

Thanks, and I hope you are well, too. And Gosh Darnit all.
I meant Volvo 960!! Uggh. Old habits are hard to break!
I need all those parts for a 960!

Dear 92volvo240,
Hope you're well and stay on. If by "belt tensioners" you referred to the drive belts, then the part numbers - which should include adjusting screws - are:
Power steering: 1346897 - $18.
Alternator: 1378789 - $40.00
Air conditioning: 9146231 - $28.00.
All should be available from a U.S.-based Volvo dealer.
Hope this helps.
Yours faithfully,
Spook

Dear 92Volvo240,
Hope you're well. The only "bad" questions are those not asked!
If the airbags (driver and passenger on a '94 940) did not deploy, there's no need to replace the front seat belt units, unless heavy use has caused the belts to fray to the point where they're "worn-out".
The pyrotechnic tensioners are not available as a replacement part: the entire seatbelt unit - belt, reel, and tensioner - must be replaced. According to Volvo VADIS - a superseded dealer parts/service database - the part numbers are #9156298 (Left) and #9156299 (Right). Both should be available from a U.S.-based Volvo dealer, for about $300 for each unit.
Before doing any work involving any SRS component (e.g., airbags and front seat-belts), be sure to disconnect the negative battery cable clamp from the negative battery terminal. Put the cable clamp into a plastic bag to isolate it. Wait 20 minutes, to be sure the SRS system is inert. An airbag deployment at close quarters can be a life-ending event.
If you use the car's radio, be sure you have the radio's security code, before cutting power. If you do not have the code, call a Volvo dealer and provide the Vehicle Identification Number (VIN). As long as the radio is the factory-installed unit, the dealer will have the four-digit security code.
There are two A/C "hoses": one from the compressor to the accumulator/drier (aluminum cylinder mounted near the firewall, on the passenger's side of the engine bay) and one from the compressor to the condenser.
These "hoses" are part metal tubing and part rubber hose. The hose from the compressor to the condenser is #6848308. It should be available from a U.S.-based Volvo dealer, for about $100. The hose from the compressor to the accumulator/drier is #6841101. I'm not sure if it is still to be had from a Volvo dealer.
Usually, the rubber hose is the part that fails. If so, a firm that makes hydraulic hoses, can remove the metal fittings from the failed hose, replace the hose, and re-clamp the metal fitting around the new rubber hose. Be sure to advise the hose-experts that the hose is for an air-conditioning system (R134a). That enables them to pick a hose that will not be degraded by the refrigerant or the lubricant.
Hope this helps.
Yours faithfully,
Spook
